With ever increasing population of the world, enhancement of food production is a major necessity. Biological principles as applied to animal husbandry  and plant breeding have a major role in our efforts to increase food production.

Dairying is the management of animals for milk and its products for human consumption.

1. In dairy farm management, we deal with the processes and systems that increase yield and improve quality of milk. Milk yield is primarily dependent on the quality of breeds in the farm.

2. Selection of good breeds having high yielding potential (under the climatic conditions of the area), combined with resistance to diseases is very important.

3. For the yield potential to be realised the cattle have to be well looked after they have to be housed well, should have adequate water and be maintained disease free.

4. The feeding of cattle should be carried out in a scientific manner – with special emphasis on the quality and quantity of fodder.

5. Besides, stringent cleanliness and hygiene (both of the cattle and the handlers) are of paramount importance while milking, storage and transport of the milk and its products.

Several new techniques like embryo transfer technology and tissue culture techniques are going to play a pivotal role in further enhancing food production.
