I want to buy a dairy cow

For dairy purchase, look for Gir, Sahiwal, HF cross, or Jersey cross. First milk her in your presence, then do a CMT test on all four quarters. Ask the lactation month, because month seven or eight cows fall in yield fast. Check age, body condition, and vaccination record. If the cow is above fifty thousand rupees, take a Pashumitra or vet with you before paying.
