Corn Silage vs Dry Fodder: The Honest Math for Dairy Farmers

Every summer the same story repeats across rural India: green fodder disappears, dry fodder prices triple, and milk yields crash by 20–30%. The farmer spends more and earns less — precisely when the dairy pays the highest summer rates.

Dry fodder (wheat or paddy straw) is roughly 90% dry matter but only 3–4% of that is usable protein, and digestibility rarely crosses 45%. It fills the stomach but starves the animal. Corn silage, by contrast, carries 8–9% crude protein on a dry matter basis with 65–70% digestibility, plus the energy of the grain cob itself.

Run the math per litre of milk, not per kilo of fodder. A buffalo eating only straw and a little concentrate gives maybe 5–6 litres in summer. The same buffalo on 18 kg of corn silage plus balanced pellets sustains 7–8 litres. Even after paying ₹5/kg for silage, the extra 2 litres at ₹60/litre deliver roughly ₹90–100 of additional net income per animal, per day.

Then there is the storage question. One acre of corn becomes 800–1,000 bales of 25 kg each — that is 20+ tonnes of feed from a single acre, sealed for 12 months, immune to rain, rats and price shocks. For a 5-animal farmer, two acres of silage is a full year of fodder security.

Our advice to every dairy farmer: don't replace your entire ration overnight. Start by replacing half your dry fodder with silage for 30 days, measure the milk, and let your own milk pail make the decision.
