Nano
Nano is not a cow breed I can verify. If you mean a small dairy cow, look for Sahiwal, Gir, HF cross, or Jersey cross. For a purchase above ₹fifty thousand, milk her in your presence, do a CMT test on all four quarters, check lactation month, and bring a Pashumitra or vet. If you want, I can show you the cow listings.
