Does the fattening cycle clear a margin?
Slide the drivers a fattener can hold over one festival cycle of about 82.5 days: the number of rams, the lean-season buy price, the festival sell price, the feed cost per ram and the mortality rate. Vet at GH¢30 and transport at GH¢50 a ram sit behind the sliders. Every figure is indicative, so overwrite each one with your own pen’s numbers.

At these numbers the cycle clears GH¢8,325, a revenue-cost ratio of 1.19. Watch what carried it there. Push the sell or the buy slider and the net moves fast; push the feed slider and it barely stirs. The festival premium, the gap between the lean-season buy and the festival sell, is the whole business, so the leverage is in buying thin animals cheap and timing the sale to the peak, not in shaving the feed bill. A dead ram is a full sale price gone, which is why mortality moves the net more than feed does.
Base case (Festival Fattening P&L, Goats and Sheep Cost and Returns Model v2): 30 rams bought at GH¢1,100 is GH¢33,000, feed at GH¢300 a ram is GH¢9,000, vet at GH¢30 a ram is GH¢900 and transport at GH¢50 a ram is GH¢1,500, for a total cost of GH¢44,400; after 5 percent mortality 28.5 rams sell at GH¢1,850 for GH¢52,725, a net of GH¢8,325 a cycle and a revenue-cost ratio of about 1.19, on a declared working-assumption cycle of about 82.5 days. Every figure is indicative: no field-validated Ghanaian small-ruminant enterprise budget exists (gap PD-8), so re-price each line against your own pen before you rely on it. The sell price is set to GH¢1,850 to match this pillar’s own worked base case5.

What swings the net most
The same cycle, re-run as a sensitivity read. Each bar is how far the net moves when that one driver is swung across the range the model uses, holding the others where you left them: prices 25 per cent each way, feed 40 per cent each way, mortality across the 0 to 20 per cent band, and the declared cycle length from 60 to 120 days. The order is the finding.
1. Sale price into the festival±GH¢26,363
The festival price the survivors fetch, set by the calendar and the exchange rate, not by the fattener. It is the widest swing of all and, once the animals are bought, the one an operator cannot move. Ghana's own 2026 Eid week moved Kumasi down about 40 percent while Accra rose, so a national festival price is not safe to assume.
2. Purchase price of the lean ram±GH¢16,500
The lean-season buy price, about 74 percent of the whole cycle cost. It is the widest swing the fattener actually decides, and 25 percent above the base the cycle barely clears its own costs. Buying well, in the lean months and in lots from several sellers, is the trade's real skill.
3. Mortality during fattening±GH¢11,100
The share of rams lost before the sale. A dead ram is a full sale price gone, not a cost avoided, which is why it swings the net wider than feed even though it never shows as a cost line. Quarantine, arrival vaccination and a deworming calendar are what buy it down.
4. Feed cost per ram±GH¢7,200
The line most operators worry about most, and it moves the net less than either price and less than mortality. Buying and storing crop residues and by-products in bulk at harvest trims it, but it is not where the cycle is won or lost.
5. Cycle length in days±GH¢6,545
The declared working-assumption cycle of about 82.5 days, carried as a swing variable and not a fact because no Ghanaian source pins it. Feed scales with days held while purchase, vet and transport do not, so it is the narrowest swing of the five, about as much as feed.
±GH¢7,200
What swinging the feed bill 40 per cent does, less than mortality’s ±GH¢11,100
±GH¢6,545
What the 60 to 120 day cycle length does, the narrowest swing of the five
Ranked by the width of the swing, the order is sale price, then purchase price, then mortality, then feed, then cycle length, and the ranking is the argument of the whole pillar in one gesture. Price moves the cycle more than anything done inside it. Feed, the line most operators fret over, swings the net by about GH¢7,200 against mortality’s GH¢11,100, and the cycle length nobody could source is narrower still at about GH¢6,546, so it matters about as much as feed. Two of the top three are prices and only one, the purchase price, is a decision the fattener actually takes; sale price follows the festival calendar and the exchange rate, so the operator who has already bought cannot move it.
Sensitivity holds the other drivers where you left them and swings one: prices 25 per cent each way, feed 40 per cent each way, mortality across the 0 to 20 per cent band, and the declared cycle length from 60 to 120 days with feed scaled by days held. On the base case that gives swings of about GH¢26,363 for sale price, GH¢16,500 for purchase price, GH¢11,100 for mortality, GH¢7,200 for feed and GH¢6,546 for cycle length. Ranks match the Sensitivity sheet of the Goats and Sheep Cost and Returns Model. Indicative figures, to validate against your own pen.
