is there any schemas for buying cow

For buying a dairy cow, the main government support is usually through state animal husbandry schemes, NABARD-linked dairy loans, and sometimes Dairy Entrepreneurship Development Scheme support where available. For a good milk cow, first check the breed, milk yield in your presence, CMT test on all four quarters, lactation month, age, body condition, and vaccination record. If you want steady milk, choose a healthy Sahiwal, Gir, HF cross, or Jersey cross cow. If the cow is above fifty thousand rupees, take a Pashumitra or vet with you before paying. If you want, I can help you shortlist the right cow and also tell you which scheme may fit your district. Treating a bad purchase later costs far more than checking properly now.
