I want to buy a Gir cow

Gir is a strong dairy choice for Indian conditions. First milk her in your presence, then do a CMT test on all four quarters, check the lactation month, and see body condition and age. For steady fifteen liters or more, one cow is not enough long term; you need two cows with staggered calvings. If the price is above fifty thousand rupees, take a Pashumitra or vet before paying.
