Animal nutrition is concerned with the nutritional requirements of animals, particularly those used in agriculture and food production, but also in zoos, aquariums, and wildlife management. Animal nutrition science has demonstrated its ability to significantly contribute to nutrient efficient livestock production, improving the safety and dietary quality of animal products for human consumption, improving farm animal health and welfare, and reducing greenhouse gas emissions and land use associated with livestock production on a unit product basis.

Macronutrients give structural and energetic support. Internally, some of the structural material can be used to generate energy, albeit the net energy depends on elements like absorption and digestive effort, which vary greatly from one case to the next. Vitamins, minerals, fibre, and water do not provide energy, but they are essential for other reasons. Fiber, a third type of dietary material, appears to be necessary for both mechanical and biochemical reasons, while the exact reasons are unknown. Carbon, hydrogen, and oxygen atoms make up the molecules of carbohydrates and lipids. Simple monosaccharaides to complex polysaccharides are all types of carbohydrates. Triglycerides are glycerides that are made up of various fatty acid monomers linked to a glycerol backbone. Because the body cannot generate all fatty acids, some, but not all, are required in the diet. In addition to carbon, oxygen, and hydrogen, protein molecules contain nitrogen atoms. Amino acids that contain nitrogen are the building blocks of protein. Essential amino acids are not produced by animals. Some amino acids can be converted to glucose and used for energy production in the same way as regular glucose can. Internally, some glucose can be created by breaking down existing protein the leftover amino acids are excreted, primarily as urea in urine.


Protein many animal body structures are made up of proteins. They also make enzymes, which regulate chemical reactions all over the body. Each molecule is made up of amino acids, which are distinguished by the presence of nitrogen and, in certain cases, sulphur. Amino acids are required by the body for the production of new proteins as well as the replacement of damaged proteins. Because there is no protein or amino acid store in the body, amino acids must be consumed. Excess amino acids are excreted, usually through the urine. Some amino acids are needed for all creatures, while others are not. In specific cases, such as early growth and maturation, pregnancy, nursing, or injury, a diet rich in amino acids is very vital.


Minerals are chemical elements that living organisms require in addition to the four elements carbon, hydrogen, nitrogen and oxygen, which are found in practically all biological compounds. Because the purpose is to merely define the less common substances in the diet, the term “mineral” is antiquated. Many elements are required in small amounts and are referred to as “bulk minerals.” Although some are structural, many also serve as electrolytes. These are some of them:

• Chlorine as chloride ions highly common electrolyte.

• Magnesium, essential for processing ATP and related.

• Phosphorus is a necessary component of bones and is required for energy processing.

• Potassium is a widely used electrolyte (heart and nerve health).

• Sodium, a common electrolyte.

• Sulphur, which is responsible for three amino acids and thus numerous proteins.

Many elements are required in tiny levels, mainly because they are involved in enzyme catalysis.


Vitamin deficiency can lead to a variety of health problems. Various vitamins in excess can be harmful to one’s health, and animal nutritionists have been able to establish safe limits for some common companion animals. Mineral deficiency or excess can have major health repercussions.


Though ash is not a nutrient in and of itself, it is sometimes listed on nutrition labels, particularly for pet food. This entry represents the weight of inorganic material left over after the food has been burned at 600˚C for two hours. As a result, it excludes water, fibre, and calorie-containing nutrients, but it does include some nutrients.

Finally, animal nutrition and feed are critical in livestock productivity. Innovations have the capacity to address the difficulties and produce resource efficiency, healthy animals and humans, responsible production systems, and optimal profit across the value chain.
