Milk production is influenced by the duration of the lactation period, which is the period of milk production after the birth of a calf.

Indian cattle belong to two different species: Bos indicus (cows) and Bos bubalis (buffaloes).

Cattle husbandry is primarily done for milk production and draught labor for agricultural activities like tilling, irrigation, and carting.

Exotic or foreign breeds like Jersey and Brown Swiss are selected for long lactation periods.

Local breeds like Red Sindhi and Sahiwal exhibit excellent resistance to diseases, making them valuable for cattle husbandry in diverse environments.
