I want a good milk cow.

Good milk cow means Sahiwal, Gir, HF cross, or Jersey cross. For steady milk, check the cow in milk, milk her in your presence, do a CMT test on all four quarters, and ask which month of lactation she is in. If you want fifteen liters or more daily, one cow will not stay at peak long; two cows with staggered calvings are better. For any purchase above fifty thousand rupees, take a Pashumitra or vet along.
