The balanced diet of livestock means that foods contain protein, sugar, fats or fat, mineral salt, vitamins or food and water in the right proportion. The importance of balanced food in the growth and formation of livestock is immense. Inadequate food causes animal malnutrition and various diseases.

Protein: protein or protein-rich food is digested into the intestine and becomes amino acid. Later, it absorbed in the gut and mixed with blood and increased the body's corrosion and growth. Because of this, body is required in the body at all ages. However, there is more demand in the growing age. With the help of blood, organic stimulants enzyme is formed inside the body. Such as pepsin, tripsin etc. These enzymes break the food protein, lipids and sugar into a simple nutrient that can absorb and exploit cells easily. The animal body, the muscular and the main part of the collagen, is made of protein. Extra protein needs of food is useful for animal strength and fat sources.

Carbohydrates: Carbohydrates provide energy in the animal body. The carbohydrate is broken down into glucose, which is absorbed in the gut and acts in the process of mixing it with blood. Extra carbohydrates are stored in the body as glycogen and if necessary, it provides the glycogen energy.

Fond or fat: Fond animal is an important component of body tissue. The cattle are mainly stored as heat and energy sources. Generally, there should be 4% fat content of cattle feed in the cattle feed.

Mineral salt: Minerals play an important role in the formation of newborn bone and tissue in the growing animal. This material maintains the shape and firmness of the skeleton. The need for minerals in animal wool, razor and horn formation Mineral helps in carrying oxygen and carbon dioxide in iron blood such as iron. Again potassium protects the acid content of animal fluid.

Vitamin: Organic compounds which are essential for their body's normal growth and health as a food component, are essential for their vitamins. Life is not possible without vitamins, but also provides adequate protein, carbohydrates, fondness and minerals to the animal body. Vitamins are essential for the growth of natural tissues, physical growth and health. If there is no vitamins in the animal or if vitamin V is not absorbed properly or vitamin C is not used properly, then it is a specific disease. For example, night blindness due to lack of vitamin A, loss of birth function, lack of vitamin 'K' causes problems in blood clotting and the failure of vitamin E 'is observed.

Water: 70 to 90 percent of the animal water. Generally 10 percent of the grains in the food grains and 15 percent of the national food is 15 percent. Again, 90 percent of the water in green grass. Despite having a lot of water in the animals, animals have to supply water separately. Because the water maintains the stability and elasticity of the body's cells. The organism structure remains in place. No chemical reaction can take place without water. Water supplies various nutrients from one organ to the other organ. Besides, water absorbs excess heat from the body. Water also serves as an important buffer.
