I want to buy a dairy cow.

Gir, Sahiwal, HF cross, and Jersey cross are the best dairy choices. Before paying, milk the cow in your presence, do a CMT test on all four quarters, check the lactation month, and avoid cows above seven years. If you want fifteen liters consistently, one cow is not enough; take two cows with staggered calvings. For any purchase above fifty thousand rupees, bring a Pashumitra or vet.
