The Sheep Enterprise: Margin, and the Risk That Comes from Another Species

#R372.38

That is the net farm income per ewe measured across 34 Laingsburg farmers running roughly 36 000 small stock units — about 77% of the sheep in the district — at 2012 conditions. Revenue R682.78 per ewe, costs R310.20, net farm income R372.38 (Conradie & Landman 2015, SAJAE 43(1)).

Do the arithmetic nobody does out loud. To clear R300 000 of net farm income at that per-ewe figure you need roughly 800 breeding ewes — plus their replacements, their rams and their lambs on the ground for part of the year. That is one household's income before drawings, before tax and before a drought. How many hectares it takes to carry them is not a number this page can give you: it comes off your district's long-term grazing capacity, adjusted for your own measured veld condition.

That figure is fourteen years old and the prices under it have moved a long way. The point is not the rand. The point is the shape: the margin on one ewe is thin, so the enterprise is decided by how many ewes your land carries and how few of them you lose.

What it costs, what it earns

The Laingsburg base case, 2012 conditions (Conradie & Landman 2015):

Line	R per ewe
Revenue	682.78
Costs	310.20
Net farm income	372.38

Income split: meat 85%, wool 15%.

Two things before you use any of it. It is a 2012 figure and every price in it has moved. And the 85/15 split is a district average across both wool and mutton systems, including Dorper flocks that cut no wool at all — so it is not the split on any one farm, least of all a Merino one. A blended average is not your farm.

#The per-ewe answer and the per-hectare answer disagree

The same study found no financial advantage to woolled sheep at 2012 conditions. Dorpers lambed 26 percentage points better; Merinos lost fewer animals to predators; the money came out level.

Now put a second, equally credible South African study next to it. A Central Karoo analysis over 2012 to 2019 found wool farms earned the best per-hectare income — 48% above mixed farms and 62% above mutton farms (AgriOrbit). The same work reports small-stock gross income of R72.18 per hectare over that period, and unit costs on mixed farms of R80.89 per hectare — around 40% higher than on specialised wool or mutton farms.

Contested — here is both sides

Wool or mutton? Two SA studies, two answers.

The mutton case. Conradie & Landman surveyed a whole district — 34 farmers, 77% of its sheep — and found no significant difference in unit production cost or net farm income per ewe between Merino and Dorper systems at 2012 conditions. Hair sheep remove shearing, crutching, blowfly-in-wool and a shed full of labour, and they lamb better. If the money is level and one system is simpler, take the simpler one.

The wool case. The Central Karoo work runs over seven years rather than one, and it measures per hectare — the denominator that decides whether the farm survives. On that basis wool farms won by a wide margin. Neither study isolates why, but the structural argument is that the wool price cycle is not the mutton price cycle, so a wool flock has two shots at a good year, and seven years contain more of both cycles than one does.

What is actually being argued. Not "which breed is better". These studies differ in period, district and denominator. One asks whether the ewe earns her keep; the other asks whether the farm earns. Both are right about their own question — and per hectare is the one that cannot be flattered by keeping fewer, bigger animals.

What settles it for you. Neither study. Your labour supply, your shearing shed and your veld type do — which is where lesson one of this module left the decision, and it has not moved.

Careful — this one bites

Do not reach for the Land Bank's Merino budget to break the tie. That budget shows a gross margin of R10 843.73 per hectare at 2023/24 prices, and it is an irrigated planted-lucerne pasture system carrying 13 sheep units per hectare (Land Bank Livestock Enterprise Budget 2023/24 v2). Setting that beside a R72.18 per hectare veld figure is the single most misleading thing you can do with a published budget. Gross margin per hectare compares enterprises competing for the same hectares — and lucerne under irrigation is not competing for Karoo veld.

While you are in that book, check its arithmetic. Its extensive Dorper budget shows R896.92/SSU gross production value less R566.08/SSU variable costs, then reports a gross margin of R161.46. It should be R330.84.

#The benchmark you are trying to beat

Two numbers from the Laingsburg work set the bar: 87 lambs tagged per 100 ewes, and a 58% sales rate.

Eighty-seven per hundred is the commercial Karoo average. Hold it against what this module already showed was achievable on unsupplemented Karoo veld — adapted composites weaning well above 130% in the Snyman and Herselman trials — and the gap between the average farm and the demonstrated ceiling is enormous. That gap is not genetics alone. It is the ewe's condition at mating, the tightness of the lambing window, the shelter she had, and the predation and theft the previous lesson told you to record separately from mortality.

Which is why the recording discipline outranks any single intervention. If predation, theft and mortality sit in one column, you cannot tell whether an 87% tagging rate is a nutrition problem, a jackal problem or a gate problem — and those three have nothing in common except that they all show up as missing lambs.

#The R26.51 that a class error costs you

Carry a cattle farmer's feel for what a class error costs and you will under-price it badly in sheep.

Classification is not abattoir custom. It is made by regulation under the Agricultural Product Standards Act 119 of 1990, and the A class means no permanent incisors — an age category, set by when you mate and when you market. A lamb that ages out of A class while you wait for a better price has cost you the whole spread. That decision has a hard deadline, and it is in the animal's mouth.

#The risk that comes from another species

Everything above is farm-level. The largest single risk to a South African wool enterprise is not.

More than 90% of the South African clip is exported, and more than 80% of exports go to China (Agribook; Daily Maverick, 14 August 2025). In 2024/25 that was 44.3 million kg greasy worth R4.44 billion, the Eastern Cape supplying 33.5% of receipts.

China has closed that market twice — both times on the back of foot-and-mouth disease in cattle. Once for about eight months following the 2019 outbreak, and again from roughly April 2022 until late August 2022 (The Post, 24 August 2022).

You may not own a single bovine. Your clip may be certified and your classing immaculate — and your market still closes, because of a disease in an animal you do not farm, in a province you have never visited.

South African specifics

This is not history. At 31 March 2026 South Africa had 1 205 open FMD outbreaks nationally — 317 in the Free State, 227 in Gauteng — against 27 closed. The WOAH free-zone-without-vaccination status was suspended in January 2019 and has not been regained, and export is permanently prohibited from the infected and protection zones (DALRRD FMD technical report, 31 March 2026). Inside a declared Disease Management Area every property carries the same movement conditions regardless of your own flock's status, so the first call before moving anything is the state veterinarian, not the buyer.

What the two closures cost South African wool growers is not known. The only figure in circulation is in Australian dollars, from an Australian trade publication — not a South African loss estimate. The closures and their dates are the fact. The price tag is not.

Do this on the farm

The balance-sheet rule that follows. Three provisions:

Keep the mutton leg. Wool and mutton fail for different reasons and, critically, mutton is domestic. A closure of the Chinese wool market does not close a Gauteng butcher. This is the strongest financial argument for a dual-purpose flock, and it has nothing to do with production efficiency.
Hold a domestic buyer relationship you did not need last year. A named abattoir or butcher who already knows you, with your paperwork under the Meat Safety Act 40 of 2000 already in order, is worth more in month three of a closure than any hedge you could have bought in month zero.
Hold cash that can carry a clip. Unlike a finished lamb, a bale does not age out of its class while you wait — but waiting costs storage, insurance and the interest on money you are not receiving, so the ability to hold is a financing question. An eight-month closure strands a full clip, so one clip's gross wool income is the smallest defensible reserve — and price it at the season's low, because a closure is exactly the event that puts you there. In 2025/26 the SA Merino indicator bottomed at R175.04/kg clean against an average of R225.42 (Cape Wools).

Keep stock theft in the same budget, on its own line: 80 600 sheep were reported stolen in the 2024/25 financial year, and sheep were 17.63% of stolen livestock value over 2007/08 to 2024/25 (African Farming, 14 July 2025). Theft is an annual cost, not a risk event.

#Now re-run the five gates

Module 1 gave you five gates, in order, to be stopped at the first honest no. Run them again with everything this module has taught you.

Do this on the farm

Three named buyers, in writing. For sheep that means at least two channels, because they fail separately: a wool broker with a fee schedule, and a registered abattoir that will take your lot size on a workable schedule. A direct-to-consumer customer is a third, not a substitute for the second.
The constraint that does not negotiate. Your veld type and rainfall pattern — wireworm and the winter protein collapse on summer-rainfall sourveld, predation and rainfall variability in the arid Karoo. Take your district's long-term grazing capacity from the DALRRD map published under Regulation 10 of the Conservation of Agricultural Resources Act 43 of 1983, then adjust for your own measured veld condition.
May you lawfully sell what this animal makes? A registered identification mark and small stock tattooed in the ear at one month under the Animal Identification Act 6 of 2002; two treatments with a scab-registered remedy for every incoming sheep, with the interval from your state vet and the product from its label; and an abattoir relationship in place before the first lamb is finished, because under the Meat Safety Act 40 of 2000 there is no lawful farm-gate slaughter-and-sell route.
Inputs, and what happens when they move. Shearing labour, classing, the dry-season lick bill, and a drench-efficacy test you should assume you need. Which of those is one supplier away from stopping your year?
The trough, the drought — and the closure. Sheep add a gate-five item cattle do not have. Fund the cash trough, fund the drought, then fund eight months of an export market switched off by a disease in someone else's herd.

If you cannot answer gate one with two channels and a fee schedule, the answer is not a better ram. It is no.

#Check yourself

3 questions — answers explained as you go

1Two South African studies reach different conclusions on wool versus mutton profitability. What is the correct way to teach the disagreement?
Why: Conradie & Landman surveyed 34 Laingsburg farmers at 2012 conditions and found no per-ewe advantage to wool; the Central Karoo analysis ran 2012–2019 and found wool farms earned the best per-hectare income. Neither is wrong. Per hectare is the denominator a regenerative course prefers, because a per-animal figure can always be improved by keeping fewer, bigger animals on the same land.
2A farmer holds 150 lambs six weeks longer hoping for a better price, and they age out of the A class. At 17 July 2026 RPO prices on 20 kg carcasses, what has that cost?
Why: At 17 July 2026 prices a 20 kg carcass grosses R2 234.00 at A2/3 and R1 703.80 at C2/3 — R530.20 gone. A class means no permanent incisors, so it expires on a date set by the animal's mouth, not by the market. Because the mutton spread is more than three times the beef spread, "hold for a better price" is a far more expensive habit in sheep than in cattle.
3Your flock is Merino, your farm has never had a bovine on it, and your clip is RWS-certified and immaculately classed. Which single event is most likely to stop you selling it?
Why: More than 90% of the SA clip is exported and more than 80% of exports go to China, which has closed that market twice on the back of FMD in cattle — about eight months after 2019, and again from roughly April to late August 2022. Scab would stop your movements, but it is your problem to fix; a price fall shrinks the cheque rather than removing the buyer; losing certification costs a premium, not a market. Only the FMD closure removes the buyer, and it is the one item here you have no control over — which is exactly why the mutton leg, the domestic buyer relationship and the cash reserve exist.
