Cattle Farming
Cattle farming is done for two purposes:
Dairy: for getting milk.
Draught: animals are used for agricultural tasks like tilling, irrigation and carting.
On the above basis, the cattle are divided into two categories:
Milch breeds (dairy animals): These include the animals which are kept for obtaining milk. Indian milch cattle belong to two different species- Cows (Bos indicus) and Buffaloes (Bos bubalis).
Draught animals: These animals are used in agriculture and transportation.
Explanation:
Milk production depends, to some extent, on the duration of the lactation period, meaning the period of milk production after the birth of a calf. So, milk production can be increased by increasing the lactation period.
The exotic breeds (e.g., Jersey, Brown Swiss) are selected for long lactation periods, while local breeds (e.g., Red Sindhi, Sahiwal) show excellent resistance to diseases. The two can be cros- bred to get animals with both the desired qualities.
