The winter pig sell-off fails the arithmetic
Selling a mature herd on Winter 1 and rebuying piglets before spring captures a real arbitrage and a respectable cheese income. It also liquidates the single most valuable asset in valley agriculture: friendship.
- The gains are real but small. Selling twelve well-kept pigs back to Marnie clears about +36,000g over their purchase price, and a temporary cow herd adds +35,600g in winter cheese.
- The cost arrives in spring. A rebuilt herd starts at zero friendship and forages roughly half the truffles of a maxed one: a one-season shortfall of about 346 truffles, worth up to −515,000g as Artisan oil.
- Net effect: −443,400g against simply holding the herd. Operators who want winter dairy income should commission a second barn, not rotate the pigs.
PELICAN TOWN – The proposition passes from farmer to farmer each fall with the confidence of settled fact. Pigs, the valley’s highest-earning animal, will not set foot outside in snow, and truffles are found only by a pig that forages. Twelve pigs in a Deluxe Barn therefore spend all of winter eating hay and producing nothing. Why feed idle capacity? Sell the herd on Winter 1, runs the argument; bank the premium Marnie pays for a well-loved animal; fill the empty stalls with cheap dairy cows; and buy piglets back in time to have them grown for Spring 1. The barn earns all winter, and spring opens at full strength.
On a napkin, it works. The Journal has now run the proposal through a full cross-seasonal profit-and-loss, using wiki-verified mechanics and market prices current to version 1.6, and can report that the napkin is missing a line item: the largest one.
§1The gains are real
Begin with what the scheme gets right. Marnie sells pigs at 16,000g. A pig kept at roughly four-and-a-half hearts sells back at about 19,000g; sale price scales with friendship, to a ceiling of 20,800g for a perfectly loved animal. Across twelve head, that is +36,000g in clean arbitrage. The timing also holds: piglets purchased on Winter 18 mature in ten nights, making them working adults by Winter 28, one day before the season turns.
The cow bridge earns its keep too. Twelve dairy cows cost 18,000g and mature in five nights, yielding 144 milk-days through Winter 17. Pressed into cheese and sold under the Artisan profession, the run clears roughly +46,400g; reselling the low-friendship cows recovers another +7,200g. Net of purchase, the bridge contributes +35,600g. So far, the scheme is roughly seventy thousand gold to the good, and its advocates generally stop counting here.
§2Friendship is capital
The error is one of accounting. A pig’s output is not fixed: on any dry day outdoors, a pig produces one truffle almost surely, then rolls for additional truffles at odds that scale directly with its friendship. A herd at maximum hearts averages about 3.0 truffles per pig per sunny day. A herd at zero friendship averages about 1.0. The herd this scheme proposes to sell would reach maximum hearts within a week of Winter 1 through routine barn care; the herd it proposes to buy would enter Spring 1 near zero and climb slowly, averaging out to roughly 1.4 truffles per pig-day across the season.
Spring offers about 18 sunny working days. The difference (1.6 truffles per pig-day, across twelve pigs) compounds to approximately 346 truffles that the rebuilt herd never finds. Pressed into Truffle Oil under the Artisan profession at 1,491g per bottle, that is a foregone −515,000g. Sold raw, at the truffle’s floor price of 625g, the shortfall still exceeds −216,000g, six times the sell-back gain the scheme is built around.
Framed as a balance sheet, the case closes itself. Friendship is not sentiment; it is accumulated capital with a measurable daily return, and it does not transfer at sale. Marnie’s premium prices the animal, not the asset.

§3What prudent operators should do instead
None of this means winter dairy income is a mistake, only that it must not be purchased with the pig herd’s friendship. The instrument already exists: a second Deluxe Barn, quoted by Robin at 25,000g plus 550 wood and 300 stone, houses a permanent cow operation in parallel. Against a spring truffle deficit measured in the hundreds of thousands, the building pays for itself inside a single avoided season, and the cheese income it produces recurs every winter thereafter.
For operators unwilling to build, the correct alternative is the traditional one: accept winter as the off-season and spend it in the mines, the greenhouse, or on the water. Neither road requires dismantling the highest-yielding animal asset in the valley. The Journal’s recommendation is unambiguous: hold the pigs.
A1 · Consolidated P&L: both profession cases
| Line item | Base (no Artisan) | Artisan + Oil Maker |
|---|---|---|
| Pig sell-back arbitrage (12 × +3,000g) | +36,000g | +36,000g |
| Cow bridge: cheese revenue net of buy/resell | +22,300g | +35,600g |
| Spring truffle production deficit (346 units) | −368,000g | −515,000g |
| Net vs. holding the herd | −309,700g | −443,400g |
Even in the most charitable reading (no Artisan profession, truffles sold raw at 625g), the deficit is approximately −216,000g, still six-fold the arbitrage gain.
A2 · The two herds, modeled
| Scenario | Truffles / pig-day | Basis |
|---|---|---|
| A · Held | ~3.0 | Herd at 4.5♥ on Winter 1 reaches maximum hearts within ~7 days of in-barn petting; sits at 1,000 friendship through spring. |
| B · Rebuilt | ~1.4 avg | New herd at 0 friendship Winter 18 → ~165 by Spring 1 (juvenile petting +15/day) → ~3.6♥ by Spring 28. Spring average ~2.2♥. |
Mechanics: a pig outdoors on a non-rainy day produces one truffle at ~99.99%; additional truffles roll at friendship/1500 as a geometric series, resolving to ~3.0 per sunny day at maximum happiness and ~1.0 at zero friendship. Spring provides ~18 sunny non-festival days at the wiki-documented 66.4% sunshine rate.
A3 · Methodology, assumptions & caveats
Reference herd: 12 pigs, Deluxe Barn, ~4.5 hearts average at Winter 1. Professions: Artisan and Oil Maker in the headline case; base case tabulated in A1. Sell price: 19,000g is an empirically observed average at ~450 friendship; the theoretical maximum is 20,800g at 1,000 friendship.
Caveats: Sunny-day counts are weather-RNG dependent, with high variance around the 18-day expectation. Sale prices vary with mood and exact friendship. The raw-truffle path softens but does not close the deficit. The Botanist profession changes truffle quality, not quantity, and does not alter this analysis.
