i purchased a cow and for eating khare rate is 130 per kg so 5 kg

Feed cost is manageable, but for a dairy cow the ration must be balanced, not just khare. If you are giving five kilogram a day at ₹one hundred thirty per kilogram, that is about ₹six hundred fifty daily for that feed alone. Add green fodder, dry fodder, and mineral mixture. If milk yield is low, the ration may be off. Tell me her milk per day and body condition, then I can guide the exact feeding plan.
