Natural beekeeping presents a valuable economic opportunity for farmers, rural populations, and aspiring entrepreneurs by blending ecological farming methods with sustainable income generation. This approach emphasizes low-cost, environmentally conscious practices that align with the natural behavior of bees, thereby minimizing production expenses while delivering high-value outputs such as honey, beeswax, pollen, royal jelly, and propolis.

One of its key strengths lies in reduced dependency on costly inputs like synthetic drugs, chemicals, and advanced machinery. By employing traditional hive models, natural pest control methods, and organic feeding practices, operational costs are kept low, making the venture accessible to small and marginal farmers with limited capital resources.

Natural beekeeping yields multiple marketable products beyond honey, enabling producers to diversify their income. Products like beeswax and royal jelly are in demand in premium sectors, both domestically and globally. With multiple harvests across seasons, this diversity ensures consistent revenue and improved economic resilience.

Global consumer trends increasingly favor natural, organic, and chemical-free products due to their health and environmental appeal. As a result, natural honey and related derivatives are gaining traction in wellness, skincare, and gourmet food markets, creating promising opportunities for certified natural beekeepers to access niche segments and export markets.

To elevate natural beekeeping from a basic subsistence activity to a sustainable and profitable venture, strong marketing approaches and entrepreneurial drive are essential. These elements enable producers to expand their customer base, enhance the value of their offerings, and establish distinctive brands that reflect the purity and ecological integrity of their products.

There is increasing interest in natural bee products both within India and globally, fueled by heightened consumer awareness around health, sustainability, and eco-friendly lifestyles. Beekeepers must identify and understand their core markets—ranging from local health-conscious buyers and organic stores to international importers—and align their product presentation, packaging, and positioning to meet specific consumer preferences. Conducting market research can help pinpoint specialized segments like organic-certified honey, therapeutic propolis, or royal jelly supplements.

Entrepreneurial opportunities go beyond harvesting raw honey. Value addition can take many forms: creamed or infused honey, honeycomb packs, artisanal beeswax candles, cosmetic products made with propolis, or balms infused with bee-derived ingredients. Packaging innovations, sustainability certifications, and appealing brand narratives further enhance consumer trust and market differentiation. Diversifying products also helps minimize risk and stabilize income.

Government schemes, policies, and training initiatives serve as vital enablers for the expansion of natural beekeeping, offering essential financial, technical, and institutional support to farmers and rural entrepreneurs. These interventions are designed to enhance productivity, sustainability, and economic resilience, particularly among smallholders, tribal communities, and women.

Subsidies and grant-based programs help reduce entry barriers by covering costs related to indigenous and modern hive types, protective gear, and honey processing equipment. This financial assistance empowers marginal farmers to embrace beekeeping while supporting certification and branding efforts that connect them with higher-value markets.

Beekeeping is now officially recognized within national and state-level agricultural policy as a key allied activity that promotes biodiversity and strengthens rural livelihoods. These policies often integrate natural beekeeping within wider organic farming frameworks and support food safety regulations, quality assurance, and export facilitation.

Government-led training programs—delivered through agricultural universities, extension networks, and specialist institutions—equip beekeepers with knowledge on colony management, disease control, and sustainable harvesting. These sessions emphasize natural methods that avoid synthetic inputs, safeguarding both pollinator health and ecological integrity.

Historical Aspects: Eighteenth Century: Antoine Lavoisier, a French scientist was known to be as ‘Founder of science of nutrition’. He established chemical basis of nutrition in his respiration experiments and introduced balance, thermometer in his studies. Along with Laplace, he designed a calorimeter through which it was demonstrated that respiration is the essential source of body heat. Even they started realizing that something is there like – carbohydrate, protein, fat and a need was felt for their investigation. But due to bad luck, French revolution took place and Lavoisier’s career was ended by
Guillotine (be – heading). As a result, further studies on nutrition suffered a setback for several years.
Second half of 19th century: Babcock, an American dairy scientist observed that feeds of different sources were eaten by animals, but there was ‘no way of knowing’, what particular contribution each of those feeds was making to animal’s needs. Therefore, he conceived the idea of trying the rations made up of entirely from a ‘single plant’. He was criticized that his research was highly impractical. Later, his younger colleagues pursued this idea in another experiment. They planned their experiment more meticulously with a greater number of animals by feeding single crop rations. But at that time, they couldn’t conclude irrespective of their exhaustive chemical studies of feeds, excreta, tissues of dead calves. It was later on that; the new discoveries provided the ‘true answer’. Later, based on this previous experience, ‘Purified diet method’ was undertaken: carbohydrate as pure starch, fat as pure lard or oil, protein as pure casein along with some minerals then known to be essential. It was revealed that there were certain other nutritionally essentials which were very important.

There are 6 nutrients which are very important to animal body – carbohydrates, proteins, minerals, vitamins and water.
Carbohydrates: These are polyhydroxy aldehyde or ketone as in monosaccharide or polymers in oligo or polysaccharides. The question arises whether carbohydrate is a dietary essential !!! Carbohydrate may not be dietary essential, but it is definitely metabolically essentially. The organic compounds – fats, proteins are oxidized only in the presence of carbohydrates. Carbohydrates are the structural components of DNA, RNA, and some other vital organic molecules. Although less than 1% is present in the human body [because, constantly being formed and broken down in metabolism], yet without the presence of this carbohydrate, the existence of living creature is at stake. Carbohydrate in the form of glucose primarily provides energy in the body and excess amount of carbohydrate is stored as glycogen in the liver and muscle. More than 50 % of the energy value of the diet is provided by carbohydrate.
Glucose + 6 O2 6 CO2 + 6 H20 Δ E (675 k. cal).
Lipids: These are important constituents of plant and animal tissue and these can be extractable from biological materials with the usual fat solubles, for example – Ether, Chloroform, Benzene, Carbon tetrachloride, Acetone etcetra. The lipid metabolism is in dynamic state. There is constant mobilization and transportation of fatty acids from the depots. Some portion of absorbed fatty acids are degraded in the same way, while others are combined with glycerol transported back to depots. All these reactions are so balanced, that mixtures of fatty acids in the depots, blood and organs tend to remain at equilibrium
condition.

Nutrition involves various bio – chemical and physiological activities which transform feed elements into body elements. These feed elements are nutrients which are digested, absorbed, utilized to build and renew the components of the animal body. As a result, animal grows and produce – milk, eggs, wool with the help of energy so produced in the body. After weaning, most of our farm animals obtain all of their feed supply from plants. Barring carnivores, the plant kingdom is the original and essential source of all animal life, because plants are able to utilize the energy of the sun to build substances which nourish
the animal. Plants make use of carbon dioxide, water and mineral salts to form carbohydrates, fats and proteins, which are utilized in the life processes of animal body. Thus, plants store and animals dissipate energy.

Carbohydrates exhibit protein sparing action, because proteins are mainly required for tissue – building, that is, general wear and tear in the body. If there is any emergency, say animal is deficient in calories of the diet, then it will use adipose and protein tissues. It is said that proteins and fats are burnt (or oxidized) in the flame of carbohydrate. It means that certain intermediary compounds of glucose oxidation through Krebs cycle, are absolutely necessary for oxidation of proteins and fats. Again, in any emergency, if glucose level of the body goes down, fats and proteins are taken over and they get metabolized faster than the body can take care of the intermediate products. However, ketone bodies – acetone, acetoacetate β – hydroxy butyrate appear in urine. In addition to above, monosaccharides are very important (vital)m structural components of many compounds which regulate metabolism. Among these are DNA, RNA for transfer of genetic information of the cell, which contain ribose and deoxy ribose sugars. Glucuronic acid occurs in the liver and this combines with toxic chemicals and bacterial by – products and hence, acts as detoxifying agent. Hyaluronic acid (a disaccharide) forms matrix of connective tissue. Heparin, a mucopolysaccharide, is very important anti – coagulant. Chondroitin sulfates are present in cartilage, bone, skin and tendon. Glycosides are widely distributed throughout the plant kingdom and a number of them have been used as drugs for animals. 
Lipids: these are the most concentrated form of the stored energy in animal kingdom, because they provide 2.25 times per unit more energy than carbohydrate. They provide insulation for vital organs protecting them from mechanical shock and also maintain body temperature. The cell membranes have phospholipids, for example – Erythrocytes. Prostaglandins exhibit hormonal activities. Essential fatty acids – linoleic, linolenic and arachidonic acids show deficiency symptoms in their absence. Lipid also delays hunger, because it requires longer time to pass through stomach than carbohydrate or protein. They also help in lubrication.

Role of water
Water is the principal constituent of living plants as well as animal body. With the maturity of seed, water content decreases. Animal body is composed of two thirds of water – intra and extra cellular fluids, and that a feed is any substance used by the body for building tissue, it is obvious that water is very important nutrient. Experiments have shown that animals may live for 100 days without organic feed, but they may die within 5 to 10 days, when deprived off water. Cell rigidity and elasticity imparts a definite form to body, which may be changed by the liquid content of the cell. Due to its high dielectric constant, oppositely charged ions co – exist in water without much interference. Hydrolysis is an important chemical process in digestion and other metabolism, where H+ and OH- ions of water are introduced into bigger molecules and these bigger molecules are broken down into smaller units.
Lubrication is yet another important function where water prevents friction or drying in joints, conjunctiva, mouth, pleura surrounding lungs, other soft organs. Body heat regulation is carried out due to certain properties – for example, due to high specific heat conducting power, water can carry away heat from the site of production and distributing it throughout the body. Yet another due to such property, highest latent heat of evaporation from skin, lungs or tongue. Oxygen and carbon di oxide are soluble in water, hence gaseous exchange takes place in the tissues, for example, fish. The “aqueous humour” of eye helps to keep up the ‘shape’ and ‘elasticity’ of the eye – ball and acts as refractive medium.

Points to ponder
• Minerals are naturally formed substances in earth. They are typically solid, inorganic, have crystal structure formed by geological processesnaturally. They may consist of single chemical element or a  compound more usually. They are identified by these characteristics: colour, streak, hardness, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility.
• Colour in minerals: Its result of brain’s interpretation of the dominant wavelength of light. “Minerals are coloured, because certain wavelengths of incident light are absorbed and the colour we perceive is produced by the remaining wavelengths that were not absorbed”. Some minerals are colourless.
• The mineral is an essential element which has a metabolic role in the body and if not provided in the diet, can cause deficiency symptoms, which can be prevented by adding that element to the diet. Animal body contains about 3% minerals, which are constant constituents of animal tissue.
• Classification is based on the amount required by the animals. Major elements are required in large amounts and are expressed in % age, whereas minor or trace elements are required in small amounts and hence expressed in parts per million (ppm) or parts per billion (ppb) or even parts per trillion (ppt) …. so on and so forth, depending on discovery of new trace element.
• They have following significant role in the cattle: health, production, reproduction, defense.

• All green leafy materials in nature have Mg, because it is the structural component of chlorophyll. Wherever such green colour is there, carotenes would be associated. The colour of carotenes is red, but this
red colour is masked by green colour of chlorophyll. Wherever above green colour is there, vitamin K would also be invariably associated. Therefore Mg, vitamin A and vitamin K would be available by – default or what!! {α, β, ϒ, δ – carotene (s)}. Hence, grazing animals generally would be receiving these nutrients. [we humans may also eat fresh green leafy vegetables {spinach (palak), bathua, methi, coriander (dhania), cabbage, knol – khol, capsicum (bell pepper, Shimla mirch) to get above nutrients]
• Vitamins help regulate body functions, keeping the body healthy and promoting resistance to dis – eases.
• Supplementation of micro – nutrients (vitamins and minerals) as pre – mix, have + ve effects on maintenance, growth, and milk production.
• Biotin, niacin, choline improves milk production in dairy cattle.
• Multivitamin tablet = A to Z0NS may be given (preferably natural sources would always be suggested).
• Vitamin ‘B’ complex, vitamins C, K are very much synthesized by rumen microbes.
Importance of vitamins and their requirements in animal health and production:
Tables 2 & 3

There are 3 types of systems for expressing the energy value of feeds and many examples have been depicted in each of these systems the world over, but here, one example has been taken up in each of these categories. [a] Digestive Nutrient Type: For example, Total Digestible Nutrient (TDN) system: Digestibility coefficients of various organic nutrients like – carbohydrate, fat and protein are determined by digestibility trials, which can be involved for total digestible nutrients as a measure of nutritive value of feeds. Hence only faecal energy loss has been considered barring losses from other channels. Hence, roughages are overestimated by such calculations. Otherwise, this method is simple, economical and has some basis for animals to be fed on such standard. The TDN value is expressed in % age as following - % TDN = % digestible crude protein + % digestible crude fibre + % digestible nitrogen free extractives + [% digestible ether extract x 2.25]. where Nitrogen Free Extractives = 100 – [crude protein % + ether extract % + crude fibre % + ash %] on dry matter basis.
[b] Production value type: For example, Starch Equivalent (S.E.) system originated from Germany, hence followed in those areas of Europe and takes into account almost all the losses involved in digestion of feed. The method is based on Carbon – Nitrogen balance studies without the help of any costly equipment, but faced some criticism too. The animals were kept in big animal calorimeter, where different sources of energy losses could be determined to the best of their ability. When it was ensured that the ration on which the animals were neither gaining nor losing weight (by measuring the intake and outgo of both carbon and nitrogen), then pure starch, straw pulp, that is, cellulose, wheat gluten (protein) and oil were added to this diet and determined the carbon and nitrogen separately again. Feeds for productive purposes are measured in terms of starch values. S.E. = Weight of fat stored per unit of feed / weight of fat stored per unit of starch x 100. That is, amount of feed required to produce as much animal fat as is being produced by unit amount of starch, when fed in addition to maintenance. For example, if linseed cake has got SE of 75, which means that 100 kgs of linseed cake can produce as much fat as 75 kgs of pure starch, when fed in addition to maintenance ration.

Crude protein of feeds contain true protein and non – protein nitrogen. True protein is made up of amino acids and for maximum efficiency, feed must have essential acids in correct proportion, correct balance as well as non – essential amino acids should also be in sufficient amounts. About digestion in simple stomached animals, the true protein is degraded to oligopeptides (less than 10 peptides) in the stomach, subsequently to mono peptide amino acids in the small intestine. Thereafter amino acids are assimilated in the small intestine.
But in ruminants, the situation is complex in the sense that feed proteins get digested in the rumen, but even amino acids are also broken down by the microbes, and thereafter, amino and carboxylic groups are released. Secondly, synthesis of new amino acids or proteins takes place for formation of their own microbial body coat. Because of these reasons, the approach for protein evaluation or expression is different in ruminant animal. Further, non-protein portion of the feed cannot be utilized effectively by non – ruminants like swine and poultry. These animals are usually fed with oil cakes, cereals and
cereal by products, which are poor in non-protein compounds, however, young succulent fodders, clover etcetera are rich in such compounds. In the laboratory, crude protein may be estimated by kjeldahl’s method and true protein may be precipitated from non – protein nitrogen fraction by treating with cupric hydroxide or trichloro acetic acid. The precipitate is filtered off and subjected to kjeldahl’s process. For experimental evaluation of non – ruminants: albino or wistar rats, rabbits, guinea pigs or poultry birds are taken. Casein (milk protein) or albumen (egg protein) are fed to these animals for a period of 4
weeks and any of the following methods are undertaken to look for the protein quality based on response of animals.

Feed processing includes all operations necessary to achieve the maximum potential of nutritional value of a feed stuff. The process involves changing ingredients in such a manner as to maximize their natural value and the net returns from their use. Feed processing may be accompanied by Physical, Chemical, Thermal, Bacterial or other changes of a feed ingredient before it is fed. The primary reasons for processing feeds are to make changes in the moisture content, density of feed, particle size, palatability; or to make more profit, to improve nutrient availability, keeping quality (shelf – life); or to reduce storage – transportation space, cost, moulds, Salmonella and other harmful substances. Feed mill equipment: The milling industry has been concerned with “Grinding” – a process of particle size reduction. During
earlier times, the same equipment was used Food for humans to produce Food for livestock because, the process was basically ‘grinding’ of whole grains. As milling developed into the “Modern Flour Industry”, the milling process was extended to include:

Anti–nutritional factors: Detoxification of undesirable components is very important, because some feeds may contain toxic substances, the excess consumption of which may cause decreased nutritive value of the feeds or may injure some vital organs or even cause death. 
Points to ponder
• Anti – nutrients present in the diet, either by themselves or their metabolic products arising in the system.
• Plants evolved these compounds as defensive mechanism against insects, parasites, bacteria and fungi.
• Feeds high in anti – nutrients: Lectins = legumes, cereal, grains, seeds, nuts, fruits, vegetables. Oxalates = spinach, swiss chard, sorrel, beat greens, beet root, rhubarb, nuts, legumes, cereal grains, sweet potatoes, potatoes. Phytate [IP6] = legumes, cereal grains, pseudo – cereals (amaranth, quinoa, millet), nuts, seeds.
• Anti – nutrient in wheat: Phytate being the most important among all, reduces the bio – availability of Iron and Zinc. There could be protease inhibitor, tannin, lectin, alkaloid, oxalate too.
• Main anti – nutrients in edible forage and fodders are: tannin, saponins, phytic acid, gossypol, lectin, amylase inhibitor, goitrogen, protease inhibitor.
• Removal of anti – nutrients: heating, boiling, soaking, spouting, fermentation. By combining different methods, many anti – nutrients can be degraded completely.

Feed Additives
Feed additives are administered to animal to enhance the effectiveness of nutrients and exert their effects in the gut or on the gut walls. Some of the common feed additives are: Antibiotics, Probiotics, Prebiotics, Arsenicals, Buffering compounds, Anti – oxidants, Enzymes, Hormones, Adsorbents, Organic acids, Flavouring agent, Pigments.
(a) Antibiotics: Chemical compounds produced by other microbes (for example, fungi, and are also synthesized in the laboratory) that, when given in small amounts, halt the growth of bacteria. They are used at therapeutic levels to treat diseases caused by bacteria. In sub – therapeutic levels added to the feed or food to enhance the rate of growth. Modes of action: They halt the growth of bacteria by interfering with their cellular metabolism by (i) Interfere with the synthesis of bacterial cell wall and cause the cell to burst, (ii) Inhibitors of protein synthesis, (iii) Inhibitors of bacterial DNA synthesis, (iv) Ionophore antibiotics – interfere with Na – K electrolyte balance, for example: Monensin sodium.
(b) Probiotics: It’s a live microbial food supplement that beneficially affects the host animal by improving the intestinal microbial balance. Beneficial microbes produce enzymes that complement the digestive ability of the host and their presence provides a barrier against invading pathogens [Figure 2].

Common feeds and fodders: An edible material which is ingested, digested, absorbed, assimilated by the animals for their benefit, is known as feed. As per the National Research Council, Dry forages and roughages are cut and cured. These are bulky feeds with low digestibility. Crude fibre is > 18 % and TDN is < than 60 % because of high cell wall content. Some of the common feed stuffs are: dry grass (hay), wheat straw, paddy straw, oat straw etcetera. Stovers [aerial part without ears and husk (maize) or aerial parts without heads (sorghum). Hulls and shells too. Pasture range plants, tree leaves and forages are either harvested or without harvesting (fresh) are also very good for feeding, for example: pasture grass, range plants, tree leaves, green forages. Concentrates have < than 18 % crude fibre and > than 60 % TDN. Feeds rich in protein (plant origin) are: Cotton seeds / cakes, Mustard cake, Groundnut cake. Whereas animal origin protein sources are: Skim milk, Fish meal, Blood meal. Feeds rich in carbohydrates (energy) in grains are: Maize, Oat, Barley. Whereas grain by – products are: Wheat bran, Rice bran, Gram husk, Pulse chuni.
Points to ponder
• Animals are sometimes said “to feed” or to eat, therefore to mean = “food for animal”. The old English root is fedan = “nourish, sustain or foster”.
• Fodders are harvested and taken to animals; whereas, Forages are browsed on by animals, while still on the land.
• Feed manufacturing refers to the process of producing animal feed from raw agricultural products; whereas, Fodder produced by manufacturing is formulated to meet specific animal nutritionrequirements for (i) different species of animals, (ii) different life stages. The idea is: to transfer the seed energy and the plant’s energy to the animal.

32 – 33. Agronomic practices for fodder production: Feeding green forages to animal is economic and better for animal health and production. To get green forage throughout the year, it is necessary to sow the crop at proper time and also to harvest it at a proper stage. According to season, following agronomical practices may be followed:
(a) Rabi crops: Berseem, Lucerne, Oat, Mustard, Sugarcane tops
(b) Zaid crops: Chari, Maize, Sorghum, Cow pea, Guar.
(c) Kharif crops: Maize, Sorghum, Cow pea, Sudan grass, Napier, Para grass.
Berseem and Lucerne (legumes) are best forages for milk production. Berseem is called as king and Lucerne as queen of the fodder crops. Maize, Sorghum, Oat (non – legumes) at flowering stage are good forages. Hybrid Napier, Guinea grass, Para grass and other green grasses are palatable, but poorer in nutritive value than legumes and many non – leguminous forages. Straws and
stovers are poor quality roughages. Average voluntary intake of legumes is 2.0 kg; Non legumes and other grasses have 2.25 kg; while of straws, stovers is only 1.5 kg Dry Matter / 100 kg body weight.

Roughage contains > than 18 % crude fibre and < than 60% Total Digestible Nutrients (T.D.N.). Leguminous fodders contain more Digestible Crude Protein (D.C.P.). Some common dry legumes are: Pea straw, Arhar straw, Lucerne hay. And some common green legumes are: Berseem (clover), Cow pea, Lucerne (alfa alfa). Non – leguminous fodders contain less D.C.P. Some common dry non – legumes are: Wheat straw, Paddy straw, Oat hay, Grass hay. Whereas, some common green legumes are: Sorghum, Maize, Oat, Napier.

Fodders and grasses can be preserved either as hay (dried fodder) or as silage (wet fodder), depending on weather conditions and available resources. These are fed in some (high input) farms to bridge seasonal scarcity periods.
Hay making: * The crop is harvested for hay making at its pre – flowering stage, when its growth is levelling off and its feeding value is still high; * Hay is best made during the rain free days; * Crops with thick and juicy stems should be dried after chaffing and conditioning, which will speed up the drying process and slow down the loss of nutrients; * Hay should be raked only a few times during the drying process in order to avoid the shattering of leaves and bleaching of the hay; * Legumes should be raked in the morning hours to avoid leaf shattering; * After drying and curing, bailing and / or stacking should be
done as early as possible. Storage under a roof is preferred; * For hay bailing, maximum permissible water concentration is 15%. Storage of hay before sufficient drying may cause fire due to spontaneous combustion; * Storage of hay with higher moisture concentration may result in mould growth, making the hay unfit for feeding.
Silage making: * Crops and plant materials rich in soluble sugars, such as – maize, sorghum, oats, sugarcane tops, hybrid Napier grass and other grasses are highly suitable for ensiling; * The dry matter concentration of the forage at the time of ensiling should be around 15 – 30 %, but higher is possibe; * Chaffing of the material for ensiling increases its compactness, thus eliminates the air space to the maximum content; * Green to semi – green forage, which may use the O2 present for respiration, results in high quality silage; * The silo should be air tight after filling; * Fermentation starts withing hours after closing the silo, and accelerates over the next 2 to 3 days. It terminates after about 3 weeks. Organic acids, primarily – lactic acid and acetic acid, ethanol and gasses such as CO2, CH4, NO2, and NH3 are produced during the fermentation process; * Due to production of acid, the pH of the biomass is reduced to a level below 4, resulting in the termination of all biological activities, after which material remains conserved under aerobic conditions.

For animal rearing it is pertinent to know the technique of keeping and preserving the feed required for the livestock. Apart from the rich pasturage, one may have the longevity of their feeds is immense concern for many. Animal feeds are an amalgam of diverse ingredients, including vegetable oil, sunflower oil. There are also animal fats, like – lard, tallow etcetera, which are included in the fodder. These elements give fodder the targeted input to animal husbandry. The prime factor that occurs and becomes a challenge for many livestock rearing, the cost for their feeds, which would provide quality and quantity in their output. Once the feed is rightly chosen for the animal, that one is rearing, the next challenge arises. Here is somehow animal feeds can be preserved safely, thereby increasing the longevity of the feeds - * Stay safe from the Sun; * Metal cans; * Storage bunkers; * Sliding metal roof bunkers;
* Commodity sheds; * Plastic containers or drums; * Re – usable freezer; * Wood bins.
Important dots
• All feed and ingredients have to be stored in a cool place [ideally below 77 0 F or (77 0F –32) X 5/9 = 25 0C), although this is not possible at outside locations under summer situations].
• Feed has to be kept dry to prevent fungal or bacterial growth.
• Prevention of entry for rodents or insects is essential.
• Stable form of vitamins is important to use.
• Anti – oxidants are important for preserving fats, oils in ingredients and feed.
• Expiry dates are important on the containers, for all feed materials for their shelf – life (for ground grains = 1 month after milling)
• For fats and oils: Opened container: 1 month; un – opened or stabilized: 1 - year post mixing.

The topic deals with methods to increase the amount of water stored in the soil profile by trapping or holding rain water where it falls, or where there is some small movement as surface run – off. Principles: Choice of method. There is no simple way of classifying methods of water conservation. One suggestion is to do it by comparing rainfall with crop requirements, giving 3 conditions: (a) Where precipitation is less than crop requirements; here the strategy includes land treatments to increase run – off onto cropped areas, following for water conservation, and the use of drought – tolerant crops with suitable management practices. (b) Where precipitation is to crop requirements, here the strategy is local conservation of precipitation maximizing storage within the soil profile, and storage of excess run – off for subsequent use. (c) Where precipitation is in excess of crop requirements; in this case the strategies are to reduce rainfall erosion, to drain surplus run – off and store it for subsequent use.
Some design principles: The effect of scale, methods for crop land: Broad bed and furrow system (BBF), Ridging and tied ridging, Conservation bench terraces (CBT; also known as Zingg terrace, and flat channel terrace); Contour furrows (also known as contour bunds and desert strip farming); Water spreading (the use of run–off areas): Natural run – off; Collected and diverted run – off; Inundation methods, Flood diversion; Surface drainage; Other sources of water: Snow, dew, mist . [Figure 4].

The term animal waste comprises, the fresh excrement, including both solid and liquid excreta and urine. * It also includes the bedding material, animal washings, feed waste and straw which are having considerable manorial value. * The characteristics of the livestock wastes depend on fractions of the digestibility, composition of feed ration and species of animals and their physiology. * The waste ruminants have different composition than obtained from swine and poultry, which is having high nutritive value.
For fodder production, the animal waste can be utilized in many ways, that is, as pesticide and that is, as non – conventional source of source energy as pesticides bio – fertilizer to improve soil fertility for sustainable agriculture. This livestock waste can be recycled in following ways: Organic mulch, As pesticides, In organic farming, Biogas production, Composting, Vermicomposting, Profitable manure management by livestock fish integration.

Orientation and general precautions in laboratory: Laboratory safety glasses or goggles should be worn in any area where chemicals are used or stored. They should also be worn any time there is chance of splashes or particulates to enter the eye. Closed – toe shoes must be worn at all times in the laboratory. Perforated shoes or sandals are not appropriate. Lab coat, gloves, eye protection, and appropriate attire (impermeable gowns, plastic aprons, masks, face shields) should be worn at all times in the lab. Long pants and shoes completely covering the top of the foot should be worn at all times when
working in the lab. Do not eat or drink in the lab at any time. Do not expose electric sparks, open flames and heating elements to organic solvent vapours.
Do not leave your assigned laboratory station without permission of the in charge. Learn the location of the fire extinguisher, eye wash station and first aid kit [A first aid manual, different sized sterile gauge pads, adhesive tape, band aids in several sizes, elastic bandage, antiseptic wipes, antibiotic ointment antiseptic solution like hydrogen peroxide]. Fire blanket, exits from the room, fire escape route. Basic life support (BLS) is important for clinical point of view. Lab safety is important because it can prevent injury, keep us from making mistakes and save lives. Following lab safety rules is part of being a good citizen. We should follow the lab safety protocols to stay safe and healthy. We cannot tell if a chemical is hazardous (radioactive !!) just by looking at it. Friedrich Esmarch, the founder of “Modern first – aid”. Emergency kit includes - * Flashlight with extra batteries, * Whistle, * Dust mask, * Local maps, * Manual can opener, * Battery powered or hand cranked radio, * Books, games, puzzles or other activities for children.

Identification / familiarization of various feed ingredients: As per National Research Council (N. R. C.), there are 8 main groups of feedstuffs. (1) Dry forages and roughages; All forage and roughage cut and cured are included in this category. These are bulky feeds with low digestibility. Crude fibre is more than 18 % and Total digestible is less than 60 % because of high cell wall contents. For example: dry grass (hay), wheat straw, paddy straw, oat straw, stovers (aerial part without ears), husk (maize) or aerial part without heads (sorghum), hulls and shells. (2) Pasture range plants, tree leaves and forages; Roughage either harvested or without harvesting (fresh) are included in this group. For example: pasture grass, range plants, tree leaves, green forages (legume and non – legume). (3) Silage; only ensiled forages are included. For example: legume non – legume silages. (4) Energy or basal feeds; Feeds are of low protein content, having crude protein less than 20 %, crude fibre less than 18 % and Total digestible nutrients more than 60 %. For example: cereal grains, milk by – products, fruits, nuts, roots etcetera; (5) Protein supplements; Feeds are of high protein , more than 20 %, crude fibre less than 18 % and Total digestible nutrients more than 60 %. For example: animal, marine, avian, and plant products. Meat meal, fish meal, oil seeds, and their cakes etcetera; (6) Mineral supplements; These are natural or pure elements. For example: composite mineral mixture or specific mineral supplements; (7) Vitaminsupplements; These are natural or pu e forms. For example: composite vitamin  pre–mix or specific vitamin supplements; (8) Feed additives; these are for improving efficiency of utilization of feeds. Number of examples have been cited elsewhere in this book [theoretical part above].

Preparation and processing of samples for chemical analysis: The preparation of samples depends upon the purpose of analysis and the nature of the constituents that are to be determined. The preparation of samples for analysis is as important as the analytical procedure and hence, it should be done with utmost care. (A) Smpling of wet material: (1) Plant material; (2) Silage; (3) Cattle faeces; (4) Sheep / goat faeces; (5) Poultry excreta; (B) Sampling of air – dry material: (I) Hay or straw; (II) Concentrates.
Small quantities of feed samples are collected from several locations, all sides, in the middle and are mixed well after chaffing. Such mixture is subjected to quarter sampling, by spreading on levelled ground in circular form. This circle is now divided into 4 equal quarters. Any 2 diagonally opposite quarters are selected and other 2 are rejected. Selected portions are mixed properly and again spread on levelled ground in circular form. This mixture is again divided into 4 equal quarters and any 2 diagonally opposite quarters are selected, while remaining 2 are rejected. This procedure is repeated till required quantity of sample is obtained. This representative sample is brought to laboratory as early for drying in a hot air oven. Dried samples are ground to pass through 2 mm sieve in a Willey mill (large samples may be ground through hammer mill), as described in chapter 10.

Proximate analysis: Weende’s system is followed. Weende was a small village in Germany, near the University of Goettingen at that time (1860), when this system was developed by Hanneburg and Stohmann. Although it is neither true nor approximate, but somewhere in the middle, that is, proximate analysis of the various parameters for assessment purpose; it gives information about the quality of feeding stuff and still followed.

Estimation of calcium and phosphorus in feeds: Calcium is precipitated as calcium oxalate by adding ammonium oxalate to acid soluble extract prepared after running a sample for ash. Precipitates of calcium oxalate are dissolved in sulfuric acid and titrated with potassium permanganate to know the content of calcium.
Using N1V1 ≡ N2V2, 1.0 ml of 0.1 KMnO4 = 2.004 mg Calcium.
Calcium, g % = Burette reading difference X 2.004 X dilution factor X 100 / weight of the sample used for preparation of acid soluble mineral extract X 1000.
[dilution factor, (for example) = 250 / 25 (ml aliquot taken) = 10]
Phosphorous present in the sample is precipitated with ammonium molybdate and the precipitates are dissolved in NaOH solution. Excess sodium hydroxide is titrated with nitric acid to calculate the actual volume of NaOH used up which is direct proportion to the Phosphorous content.
1 ml of 0.1 N NaOH = 0.1347 mg Phosphorus
Phosphorus % = Actual volume of 0.1N NaOH solution used to dissolve precipitate X 0.1347 X dilution factor X100 / weight of sample used for acid soluble extract X 1000
[Here, dilution factor is 250 / 50 (aliquot taken) = 5]

Qualitative detection of undesirable constituents, adulterants in Feeds: The nutritive value of feed ingredients from the same origin may exhibit variation. The factors which are responsible for the variation are natural variation are natural variation, processing, adulteration and damage, deterioration. These days, due to shortage and high prices of feed ingredients, adulteration is one of the main problems. Feed quality can be examined by different techniques:
(a) Feed microscopy: Stereo or compound microscopy may be used for: (i) Screening method; (ii) Floatation technique.
(b) Chemical tests: For heavy metals, nitrates, phosphates, sulfates, free sulfur, salts: carbonate, chloride, salt, sugar, urea, blood, hoof or horn, leather meal, uric acid.

Familiarization with various fertilizers, manure and Agri – implements: Manure: * Nutrients are added to soil for healthy growth of plants. * Continuous growing of crops makes the soil poor in nutrients. * Manures are organic substances obtained from decomposition of plants animal wastes. * Manuring is done to replenish soil with nutrients.
Advantages of manuring: * Improves water retaining capacity of the soil. * Makes the soil porous and exchange of gases becomes easy. * Increases the number of friendly microbes. * Improves the texture of the soil. * Replenishes the soil with necessary nutrients.
Fertilizers: * These are chemical substances rich in nutrients. * These are produced in factories.
Advantages of fertilizers: * Help farmers to get better yield of crops.
Disadvantages of fertilizers: * Sources of water pollution. * Make the soil less fertile. * Artificial fertilizers often cause diseases.

Estimation of silage quality parameters: Process of making silage is called ensiling. The green fodder harvested at a proper stage is stored, packed and compressed in silo and it is then tightly covered to prevent the contact with air. Thus, the forage is preserved by controlled microbial anaerobic fermentation in a silo with minimum loss of nutrients for use as a succulent fodder during scarcity (lean) period. This form of preserved fodder is known as silage. Silage is prepared by obtaining enough acid content in ensiled feed which inhibit the microbial fermentation thereby preserving the green fodder. Following are
points to ponder:
1. Maize, sorghum, bajra crops having thick solid stems and rich in soluble carbohydrates, are best for silage preparation. Silage can also be prepared from oats, berseem etcetera, after wilting to 35 – 40 % dry matter.
2. Dry matter content in fodder crop for ensiling should be between 30 – 40 % (average 35 %) and should have sufficient soluble sugars for acid production during fermentation.
3. The crop is harvested in bloom stage, which is best for silage preparation.
4. If the crop is deficient in soluble carbohydrates, (for example, legumes), then a sugar industry by – product is added.
5. Silage having acidic flavour and pH 3.5 to 4.2 is considered to be excellent.
6. The crop should be properly trampled / pressed to remove the air out of silo.
7. The crop is chopped into small pieces for better microbial action due to increased surface are and sufficient acid production.

A DSLR, or “Digital Single Lens Reflex” camera, uses a mirror mechanism to direct light from the lens to an optical viewfinder, allowing the photographer to see exactly what the lens sees. When the shutter is activated, the mirror moves aside, allowing light to reach the image sensor, capturing the photograph. While single-lens reflex cameras have been around in various forms since the 19th century, initially relying on film, the first commercially available digital SLR with an image sensor emerged in 1991. Unlike point-and-shoot or phone cameras, DSLR cameras allow for interchangeable lenses, offering greater
flexibility.
Working Principles of DSLR Camera
When using a DSLR camera, the image seen through the viewfinder at the back of the camera is the actual view through the lens. This ensures you are previewing the precise scene you intend to capture. Light from the scene enters through the lens and hits a reflex mirror positioned at a 45-degree angle inside the camera. This mirror directs the light vertically to an optical component known as a “pentaprism.” The pent prism then reorients the light horizontally by passing it through two internal mirrors, delivering the final image into the viewfinder.
