Material handling includes a number of operations that can be executed either by hand (manual) or by mechanical means or devices to convey material and to reduce the human drudgery.

The most common types of mechanical devices for grain handling are;

The oxygen content may be measured either chemically or electronically. The normal chemical method is the so-called Winkler method which is a titration method, consisting of adding certain chemicals to the water and observing a colour change which will be directly related to the oxygen concentration.

The world’s largest population of milch cattle lives in India. In 2020, there were almost 906 million tones of milk produced worldwide, with India being the top producer with a 22 percent share. Annual Growth Rate of milk production in 2019-20 in India was 5.69 per cent. Highest growth rate in milk production was found to be 14.31 per cent in Karnataka. In 2021, the Indian dairy market had a value of INR 13,174 billion.

India has an enormous wealth of cattle, which is crucial to the development of the socioeconomic status of millions of rural households as well as the country’s economy. In addition to giving millions of people access to lowcost nutritious food, this industry plays a significant role in boosting family incomes and creating gainful employment in rural areas, notably among landless laborers, small and marginal farmers, and women.

All across the world, the dairy industry is facing numerous problems and changes. Dairy development has received a considerable boost from factors including access to technical advancements, improvements in infrastructural facilities, and the development of modern marketing insights. It is interesting to see how the dairy sector is changing globally.

In India, the Ministry of Health and Family Welfare (MOH&FW), dealing with the subject of food quality and safety at the national level, has been designated the nodal ministry for maintaining food standards. The instrument for ensuring food quality and safety at the national level is through a legislation titled Prevention of Food Adulteration Act, 1954 (PFA) and Rules made there under as amended from time-to-time.

The world’s greatest source of cow and buffalo diversity is India, and countries like Australia, South Africa, Latin America, and the USA employ Indian cattle breeds to grow their livestock industries. The number of cattle in the nation represents 17% of all cattle in the world. 22-25% of the Indian cow population is made up of the best native milk, draught, and dual-purpose animal genetics. The majority of local cattle breeds are excellent drafters. Native livestock breeds are clearly superior in their use of subpar feed, have better heat tolerance, and greater resistance to tropical diseases.

India is home to an enormous number of buffalo. According to the 20th Livestock Census, more than 109 million buffaloes, or more than 56% of the world’s population, are living in India. With 20 recognized breeds, it also has a very diverse collection of buffalo genetics. One of the most well-known buffalo breeds in the world, the Murrah, is also found in India. The buffalo is a versatile animal that can be used for milk, meat, and draught. India is the world leader in this industry, producing 76% of the world’s buffalo milk.

Dairy farmers are faced with a number of fundamental inquiries. The first inquires as to what dairy animal he needs to keep. Is the breed with the best production performance the one that has adapted to the local environment the most? What animal is the best, asks the second? Is it the one with a showwinning conformation or the one with a strong ancestry? Is the ideal dairy cow one that produces the most milk, has the best feet, legs, and udder support, or combines the performance of these characteristics in the best possible way?

Herd management practices in the handling, nutrition, milking techniques, sanitation, and housing of dairy animals play key roles in predisposing the individual animal as well as herds to diseases. The key factor influencing the reduction of health issues are the decisions made by herd managers or animal owners.In order to maximize output and profitability through disease control, herd management approaches in conjunction with a veterinarian programme can be most beneficial.

The proper supply of feed and fodder is a requirement for the growth and development of the animals. Over the past few decades, there has been a considerable growth in milk production, with India now producing the most milk in the world (187.7 million tones in 2018–19). The main causes of India’s low milk yield are extrinsic (poor nutrition/feed management) as well as intrinsic (low genetic potential).

In terms of their contribution to human nutrition, the dairy industry is very important. Since dairy farming has the ability to offer meaningful selfemployment and stable income, it is a dependable source of subsistence for the rural poor. Additionally, it requires less labour and cash to maintain. Dairy cattle feeding directly affect the animals’ ability to reproduce and produce. Therefore, the addition of a mineral mixture is necessary to maximize the animal’s productivity and milk output.

For the purpose of passing into the lower gastrointestinal tract and supplying the cow with vital amino acids, dairy bypass protein (UDP – undegraded protein) is a type of animal or plant-based protein that resists breakdown in the rumen. More metabolizable protein is made available by avoiding the rumen, assisting the cow in meeting her needs for amino acids for milk production and its constituent parts.

Dietary fat, which is not degraded in upper part of digestive tract (rumen) of animal, but gets digested in lower alimentary tract is known as bypass fat. Rumen protected fat is another name for this bypass fat. Immediately following calving, dairy animals lose a significant amount of energy through milk, although their feed intake is decreased. Animals continue to have negative energy balances as a result.

By minimizing the harsh climate effects like heat, cold and rain, it is crucial to offer the proper circumstances for raising dairy cows in the tropics. Stress can be reduced through the design of the farm and the dwelling. Controlling the environment lowers the risk of stress and disease, improves management, and increases milk production.

Dairy farmers hope to have better milking cows than those in their current herds. A solid foundation is necessary for every farming operation. Undoubtedly, the dairy farm documentation system is among the most important facets of farm management. Tracking each cow’s productivity within a herd and assisting breed development generally are the major objectives of a dairy farm tracking system. This information could be referred to as production data.

Animals need to function efficiently during reproduction in order for a dairy production system to be sustainable. This is necessary to produce milk, the primary product of interest, as well as to supply replacement animals. From the perspective of reproduction, delayed puberty, lengthy calving intervals, limited productive lives, and high calf mortality are the key variables that cause economic losses. Reproductive management’s proportionate contribution to the effectiveness of dairy production systems varies greatly.

Letting the cow to release its milk so the dairy farmer can extract it for personal use or to sell is the procedure of milking. Consequently, it is not totally a natural process. The natural process must be manipulated by the dairy farmer to his advantage. Therefore, in order to control the natural process, one must first understand it. The process of producing milk from blood-derived basic materials by alveolar cells and storing it in the alveolar cavity is known as milk secretion. Only when the alveolar cavity is full and the pressure on the alveolar cells prevents further secretion does this continuous process come to an end.

Operation Flood and dairy cooperatives became India’s greatest rural employment programme, enabling the modernization of the dairy industry to a point from where it may take off to fulfill the need for milk and milk products within the nation as well as chances on the international market. An unorganized sector handles 80% of the milk a rural producer produces, and an organized sector handles the remaining 20%. It has been discovered that dairy cooperatives significantly contribute to reducing rural poverty by increasing rural milk production and marketing.

The cradle-to-grave dairy supply chain includes a number of operations that result in greenhouse gas (GHG) emissions related to milk production. These activities broadly include the use of agricultural inputs like fertilizers, fossil fuel for the production of animal feed and fodder, processing concentrates in cattle feed plants, enteric fermentation, manure management, and post farm gate activities like processing milk at dairy cooperative societies, milk unions, its conversion into different milk products, and their distribution through retail supply chains.

The Indian economy, which meets its own dairy demands, has reached a turning point with its bovine breeding initiatives. The viability of this enterprise, however, depends largely on completing as many successful artificial insemination cycles at a cattle farm. Estrus behaviour observation is used to determine when artificial insemination should take place. But since not all cattle exhibit substantial estrus symptoms, insemination results are not always reliable. An estrus detecting instrument known as an Electronic Nose (eNose) is created to address these issues.

The International Ergonomics Association (IEA) defines ergonomics or human factors as the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design to optimize human well-being and overall system performance.

Physical ergonomics is concerned with human anatomical, anthropometric, physiological and biomechanical characteristics as they relate to physical activity. This is the ergonomics domain we are most concerned with in the workplace, and most of the content on this site is very much focused on workplace ergonomics.Physical ergonomic principles have been widely used in the design of both consumer and industrial products for optimizing performance and to preventing / treating work-related disorders by reducing the mechanisms behind mechanically induced acute and chronic musculoskeletal injuries / disorders.

There are 8 fundamental Ergonomic Principles for better work performance which help you identify ergonomic risk factors and maintain your stellar safety record.
• Maintain neutral posture
• Work in power zone
• Allow for movement and stretching
• Reduce excessive force
• Reduce excessive motion
• Minimize contact stress
• Reduce excessive vibration
• Provide adequate lighting

The parent material to which a coating or plating is applied is known as the base material. The phrase base material is used to distinguish the overall part, numerous layers, and the original base material. Coating, electroplating, welding, and soldering all depend heavily on base materials.

Anthropometry is the study of the measurement of the human body in terms of the dimensions of bone, muscle, and adipose (fat) tissue. It is a branch of anthropology dealing with measurements of human body to determine difference in groups and individuals. The word “anthropometry” is derived from the Greek word “anthropo” meaning “human” and the Greek word “metron” meaning “measure” (Ulajaszek, 1994).

The rate of consumption of time and energy in task completion is affected by the work area. The work area is composed of the height, available space of the work surface, the location of the equipment, materials, and supplies being used. The work surface should be at the optimum height for the position you assume in task completion. This means if you are standing, the surface height should be slightly below your waistline.

The level of motivation of an individual has a definite relation to the fatigue experienced while doing any work. When a person dislikes a task, motivation to do is low and fatigue sets in faster. Interest in job produces high motivation and prevents fatigue. Besides the way of carrying a task is of great concern if we want to maintain our right posture, in order that we do not have to face any musculoskeletal disorders.

Work simplification is the conscious seeking of the simplest, easiest, and quickest method of doing work. It describes the making of daily tasks easier in order to reduce strain or to decrease the amount energy required to complete an activity. Work simplification research consists of making motion and time studies of the work as it is being done, analyzing the work methods, developing the easiest and most effective way to do the task and putting the new method into use. Time and energy are closely related and if these are blended properly the work of the housewife will be much simplified.

Home cooking is all about simple, tasty and healthy food brought from the kitchen to the dining table. But oftentimes, preparing the food can be timeconsuming and tedious. With the right list of basic kitchen tools, utensils and appliances, we can make cooking more enjoyable and a lot easier. These appliances can also motivate us to think of creative new recipes to delight our loved ones.

Appliances which help or assist in doing household work as cooking, cleaning and food preservation are known as equipments. A equipment also referred to as a domestic appliance or an electric appliance or a household appliance.

Today, we have spoons made of different sizes and materials such as metal, wood, plastic, ceramic or a combination of two or more materials. The most popular material is the stainless steel. Spoons are used primarily for eating liquid or semi-liquid foods, such as soup, stew or ice cream, and very small or powdery solid items which cannot be easily lifted with a fork, such as rice, sugar, cereals and green peas.

Pressure cookers are pans made of Aluminum or stainless steel. They are available in different sizes. The pressure cooker was invented in the seventeenth century by the physicist Denis Papin, and works by expelling air from the vessel, and trapping the steam produced from the boiling liquid inside. This raises the internal pressures and permits higher cooking temperatures. This, together with high thermal heat transfer from the steam, cooks food far more quickly, often cooking in between half and a quarter the time for conventional boiling. After cooking, the steam pressure is lowered back to ambient atmospheric pressure, so that the vessel can be opened safely.

Cookware is food preparation equipment, such as cooking pots and pans, used in kitchens. There are several different types of pots and pans- nonstick, ceramic, stainless steel, cast-iron and more. If you’re only going to buy one, we suggest a heavy-duty, try-ply or multi-clad stainless steel pan. They’re expensive, but they’ll last a lifetime with proper use.

Method: To check the performance of these pans, prepare 3 besan chillas on each type of pan by using equal quantity of oil and batter. Then compare and evaluate prepared dishes on 5 parameters i.e. Appearance, Texture, Aroma, Color and Taste by using 9-point hedonic scale.

The toaster is a kind of equipment used to toast bread in order to make it crisp. It has two slots which can hold two or four slices of bread. The electrical element produces the heat needed to make the bread hot and crisp. The toaster is a little apparatus intended to toast numerous sorts of bread items. Created in Scotland in 1893 and persistently created from that point forward, the most well-known family unit toasting machines are presently the pop-up toaster and the toaster broiler. Pop-up toasters make toast from bread in 1 to 3 minutes by utilizing warmth components.

A vacuum cleaner, also known as a sweeper or hoover, is a device that uses an air pump (a centrifugal fan in all but some of the very oldest models), to create a partial vacuum to suck up dust and dirt from fl oors and from other surfaces such as upholstery and draperies.The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil.

A microwave oven, commonly referred to as a microwave, is a kitchen appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave spectrum.

The domestic electric food juicer/mixer/grinder has become an integral fixture in the typical modern kitchen. Generally functional as liquidizers, grinders and juicers, this paraphernalia comes in handy for grinding/pulverizing/powdering dry foodstuffs either raw or roasted (cereals, grains, masalas, coffee seeds, etc.), for mixing liquids and for converting food— with or without the presence of water (or vegetable oils)—into forms of slurry or pulps. It is also used for extracting juice from fruits or vegetables.

The refrigerator (called a ‘fridge’ by most people) is a box like equipment which uses electricity to keep the temperature inside the box lower than the atmosphere outside. Food kept at such a low temperature thus does not spoil for a long time. The refrigerator also serves the purpose of giving us cold water and ice in summer. By preserving food in the refrigerator, one can delay the growth of bacteria, keep food items fresh and thus save time and energy of the homemaker in meal preparation.

A washing machine laundry machine, clothes washer, or washer) is a device used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids, and is performed by specialist businesses) or ultrasonic cleaners. The user adds laundry detergent which is sold in liquid or powder form to the wash water.

Washing dishes is not the most rewarding task. Cooking can be creative, but cleaning up afterward seems like a waste of time and leaves the person washing complaining about “dishpan hands.” The development of the dishwasher has helped relieve some of the monotony, as well as the grease and grime.

Electric Cooking Range is also known as an electric stove or electric range; is a stove with a built-in cooktop and with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solidfuel (wood or coal) stoves which required more labor to operate and maintain. “Cookstoves” (also called “cooking stoves” or “wood stoves”) are heated by burning wood or charcoal; “gas stoves” are heated by gas; and “electric stoves” by electricity. Unlike gas stoves, electric stove tops don’t produce a flame.

A solar cooker or solar oven is a device which uses the energy of sunlight to heat food or to cook it or sterilize it by means of reflective panels that concentrate the light on to a dark coloured pot in an insulated box.

To learn the design and arrangement of space in the kitchen which is the key in the pattern of living, the number of people to be served in the area, the size of the house and the equipment and furnishing in the kitchen. To know the most important aspect to consider in planning a kitchen i.e., the nature of the primary and secondary activities to be performed in the kitchen.

Every homemaker spends a chunk of her time in the kitchen. Kitchen is the most functional part of the house. It needs to be carefully designed. Kitchen ergonomics comes into play to make the kitchen a comfortable place to work. Kitchen ergonomics is all about minimizing the movements and stress we have to go through while cooking. While designing your kitchen you need to keep in mind the heights of various surfaces, distances and placement of items to make your space functional, efficient and enable effortless cooking.

Milk is considered to be a perfect food which contains almost all the macroand micronutrients required for normal body growth. However, it is highly perishable in nature which poses problem during its storage. It gets spoiled within few hours after milking if not processed or cooled immediately. It can also be a source of several disease causing microbes as it is conducive for the growth of microorganisms.

High-pressure processing (HPP) is a novel method for non-thermal preservation technique of food that inactivates harmful pathogens and vegetative spoilage microorganisms. HPP is an alternate, non-thermal food processing method, wherein the food is subjected to a very high pressure range from 100 -800 MPa (1MPa = 145.03 Psi or 10 Bar). HPP is also referred as High hydrostatic pressure processing, Ultra high-pressure processing, Hyperbaric processing and Pascalization (Rao et al., 2014).

Electricity is one of the fundamental phenomena of nature. Electricity or electric current is caused due to the movement of charged particles i.e., electrons. Due to the potential difference between two points in a conductor, electron movement takes place. The potential difference between two points is caused due to the difference in charge density. Electron tends to flow from lower potential to higher potential which causes electricity to flow. In general, the electrons flow from cathode (negative) to anode (positive) but in a wire electricity, electrons flow from anode to cathode when connected to a battery or any electricity source.
