Animal husbandry is the science of caring and breeding of domestic animals and the development of genetic traits such as high yielding, disease resistance, etc. that are valuable to humanity.
Dairy farm management is the management of the animals that provide milk (milch animals). The goal is to enhance the quantity and quality of the milk produced. For this purpose, high yielding and disease resistant breeds are maintained in a strictly hygienic manner with proper housing, adequate water supply, and nutrient-rich fodder. Regular inspection and record-keeping ensures that a good high-quality yield is generated.
