How lactation profit really works
Most dairy-farm calculators will cheerfully tell you that a cow giving 12 L per day at ₹55 is "earning" ₹660 a day. That is a fantasy number. It ignores feed cost, vet cost, dry-period overhead, and the fact that your cow does not milk 365 days a year. This calculator does the math honestly so you can decide whether your animals are actually profitable.
The four hidden costs
- Dry period: 60-90 days a year when the animal gives zero milk but still eats ~65% of her normal feed. This alone is a ₹15,000-25,000 cost per animal per year.
- Feed quality drift: Most farmers buy concentrate weekly at market prices that vary by 15-30% between monsoon and summer. Average honestly, not at the cheapest rate.
- Veterinary & breeding: Routine vaccinations, deworming, mineral mixture, AI charges, pregnancy confirmation. Add it all up monthly — it averages ₹40-70 per day per animal.
- Labour: Even if you milk yourself, your time has a cost. One labourer is typically one full wage per 5-6 animals.
What a "good" margin looks like
A well-run small Indian dairy farm with 5-10 animals targets 35-45% gross margin (before buildings and capex). Under 20% is fragile — one monsoon disease outbreak or one feed-price spike, and you are at a loss. Above 50% is usually a sign you are under-costing feed or vet expenses.
How to improve profit per animal
- Balance the ration. Over-feed concentrate is the #1 cost leak. Match concentrate to actual milk yield — 1 kg extra per 2.5 L of milk.
- Cull chronic low-yielders. A cow giving under 8 L is almost always running at a loss in India today. Replace her within the next 2 cycles.
- Sell direct. Middlemen take ₹5-12/L. Even small home-delivery routes to 10 customers move you from loss to profit.
- Use every drop of the dry period productively — well-fed dry cows return to higher peak yields in the next cycle.
