I want to buy a high milk cow

For high milk, choose HF cross, Jersey cross, Sahiwal, or Gir. First milk the cow in your presence, then do a CMT test on all four quarters, ask the lactation month, and check age and body condition. If the price is above fifty thousand rupees, take a Pashumitra or vet with you. If you want fifteen liters or more daily, buy two cows with staggered calvings for steady supply.
