I want a cow in west bengal

For West Bengal, a Jersey cross or HF cross is usually the best dairy choice. If you want more heat tolerance and easier management, Sahiwal is also a strong option. Before paying, milk the cow in your presence, do a CMT test on all four quarters, ask which month of lactation she is in, and check body condition and age. If the animal costs above fifty thousand rupees, take a Pashumitra or vet with you.
