When a farmer tells us milk is down, the cause is almost never a mystery. In our experience it is one of a handful of things, and nearly all of them are about feeding. Here they are in the order we would work through them.
1. Fix the protein gap first
This is the most common gap we see, and the one that responds fastest. A cow producing 10 litres a day needs substantially more protein than one producing 4, and straw plus a little grain does not supply it. When protein is short, the cow will hold body condition and cut milk — that is simply how her metabolism prioritises.
Protein sources that make sense at smallholder scale include Beer Poosa (brewer's spent grain), groundnut cake, cottonseed cake and gram husk. Beer Poosa tends to be the cheapest per kilogram of protein delivered, which is why it has become the default around Kalavai.
2. Do not cut green fodder
Green fodder is the foundation, not a luxury to drop when concentrate looks expensive. It supplies fermentable fibre, vitamin A precursors and moisture. Aim for as much as your land and season allow. If green is genuinely short, a good dry roughage plus a protein supplement is the fallback — but it is a fallback.
3. Get the mineral mixture right
The cheapest item in the shed and the most frequently skipped. Calcium, phosphorus, and trace minerals directly affect milk production, fertility and the ability to hold a lactation. Fifty to a hundred grams a day of a decent mineral mixture is not optional if you want consistent yield.
4. Water is a feed
A cow producing 10 litres of milk drinks 60 to 80 litres of water a day, more in hot weather. If the trough runs dry between fillings, or the water is dirty enough that she drinks reluctantly, yield drops before anything else shows. Clean water available at all times is one of the cheapest yield improvements available.
5. Keep the routine boring
Cattle are creatures of habit to a degree that surprises new farmers. Feeding and milking at the same times each day measurably supports yield. Sudden ration changes, irregular milking intervals and disruption all cost milk. When you do change feed, change it over a week, not overnight.
6. Manage heat
From March to June, heat stress is a real and underestimated cause of yield loss in Tamil Nadu. Shade, airflow and access to water matter more than most feed adjustments during those months. Feeding the heavier portion of the ration in the cooler early morning and evening helps — cattle eat less during the hottest part of the day regardless of what you offer.
7. Watch body condition, not just the milk can
A cow who is losing condition while milking well is running on her own reserves, and that yield will fall away and take her next lactation with it. A cow gaining condition on a heavy ration is being overfed energy relative to what she is producing. Run your hand over the ribs and hip bones weekly; it tells you more than a week of yield figures.
A worked example
A crossbred cow giving 8 litres, on straw, 2 kg of a grain mix and grazing:
| Change | What to do | Realistic effect |
|---|---|---|
| Add protein | 6–8 kg wet Beer Poosa daily, introduced over a week | The largest single gain in most cases |
| Add minerals | 60 g mineral mixture daily | Steadier yield, better fertility |
| Water | Trough never empty, cleaned daily | Noticeable within days |
| Green fodder | Whatever is available, daily | Supports everything above |
| Routine | Same feeding and milking times | Reduces day-to-day variation |
We deliberately have not put a litre figure on that table. Anyone who promises you a specific increase is guessing. What we can say is that these five changes together are what has worked for the farmers we supply, and that the protein change is usually the one they notice first.
What to be sceptical about
- Anything injected to raise yield. Ask a veterinarian before it goes anywhere near your animal.
- Feeds sold on a promised number of extra litres. Nobody can know that without knowing your ration.
- Very cheap concentrate of unknown composition. If the price is far below the market, something is filling it.
Sound feeding is unglamorous and it works. If you want help putting a ration together for your herd, call us — we do this with farmers most days, and we will tell you honestly if feed is not your problem.
