We sell Beer Poosa and maize feed, so you should read this knowing where we stand. That said, no single feed wins on everything, and telling a farmer otherwise is how you lose a customer for good. Here is the comparison as we would give it across the counter.
The four feeds side by side
| Feed | Protein (of DM) | Energy | Main strength | Main drawback |
|---|---|---|---|---|
| Beer Poosa (spent grain) | 20 – 28% | Moderate | Cheapest protein per rupee; low acidosis risk | Wet — spoils in 3–5 days |
| Cottonseed cake | 22 – 26% | Moderate | Stores for months; widely available | Gossypol limits; costlier per kg protein |
| Groundnut cake | 40 – 45% | Moderate | Very high protein; small quantities go far | Expensive; aflatoxin risk if stored damp |
| Maize feed | 8 – 10% | High | Best energy source; excellent palatability | Low protein — cannot fill a protein gap |
Read that table as complements, not competitors. The most common good ration in our area uses Beer Poosa for protein and maize for energy, with a mineral mixture and whatever green fodder is available.
Cost per kilogram of protein
Comparing feeds by price per kilogram is misleading, because you are not buying kilograms — you are buying nutrients. The number that matters is what a kilogram of actual protein costs you.
Work it out yourself with your local prices: divide the price per kg by the protein fraction, and for wet feeds remember to account for dry matter. For Beer Poosa at 22% dry matter and 24% protein of dry matter, one kilogram of wet feed carries only about 53 grams of protein — so you need roughly 19 kg of wet feed per kilogram of protein. Even so, at typical local prices it usually still comes out cheapest, because the price per kilogram is so much lower.
Where each one actually wins
Choose Beer Poosa when
- You can collect or receive it at least twice a week — freshness is the whole constraint.
- You want the lowest cost per kilogram of protein.
- You are feeding a good number of animals, so a load gets used quickly.
- You want to raise protein without adding starch and acidosis risk.
Choose cottonseed cake when
- You are remote and can only buy once a month — it stores well.
- You have no dry, shaded place to keep a wet feed.
- You keep only one or two animals and a bulk wet load would spoil.
Choose groundnut cake when
- You need a concentrated protein top-up in small daily amounts.
- You can store it genuinely dry — damp groundnut cake and aflatoxin is a serious problem, not a theoretical one.
Choose maize feed when
- Energy is the gap, not protein — thin cows on adequate protein.
- You need palatability to get a fussy or recovering animal eating.
- You are pairing it with a protein source. On its own it will not lift yield much.
The honest case against Beer Poosa
It is wet and it spoils. If you keep two cows, live twenty kilometres away and can only come to town once a fortnight, Beer Poosa is the wrong feed for you and a stored cake is the right one. We would rather tell you that than sell you a sack that goes mouldy in your shed.
It also varies between loads more than a manufactured feed does, because it is a by-product of someone else's process. A good supplier manages that by turning stock over quickly and being straight with you about what arrived when.
What we would actually suggest
For most smallholders in the Ranipet and Vellore area with three or more milch animals: Beer Poosa as the protein base, maize feed for energy, a mineral mixture daily, and as much green fodder as the season allows. Cottonseed or groundnut cake as a top-up when you need it or when spent grain is short.
