I need cow rs 30000 10 ltr milk

For thirty thousand rupees and ten liters milk, look for a healthy Sahiwal, Gir, or good HF cross cow. At this budget, a fresh milker is rare, so check the cow in your presence, do a CMT test on all four quarters, and ask which month of lactation she is in. If she is in month seven or eight, milk will drop soon. For a cow above fifty thousand, take a Pashumitra or vet along.
