The Pig: Breeding, Rearing, and Marketing — Themes and Context

Housing and the Problem of Draughts

Spencer devotes considerable attention to pig housing, and his central concern is ventilation without draught. He criticises the common sty with a yard attached, calling it unhealthy for growing pigs and cruel for newborn ones in cold weather. The loss of piglets from exposure, he says, is annual and substantial.

His preferred solution is a tall building, like a barn with a thatched roof, divided into sties by partitions about four and a half feet high. He argues that a height of at least ten feet for side walls allows thorough ventilation while keeping the temperature stable. He also describes a row of south-facing houses with brick foundations, feather-edged boards, and unpointed tile roofs that can be packed with straw in winter. The key, he insists, is not costliness but comfort: pigs thrive best in a dry bed free from extremes of heat and cold.

Breeds and the Breeder’s Eye

The book includes standard descriptions and scales of points for pure breeds, but Spencer’s own judgments are what stand out. He praises the Middle White sow in the forefront of the frontispiece as one of the best ever bred, and he names her—Holywell Countess Victoria. Such specific praise is rare in a manual, and it suggests a breeder’s pride.

He also discusses cross-bred pigs, though the excerpts give only a hint of his views. The chapter on selection of the boar and sow, and the separate chapter on the sow’s udder, indicate that he values functional anatomy over mere appearance. The udder chapter, in particular, points to a practical concern for the sow’s ability to nourish her litter.

The Economics of Pig-Keeping

Spencer is alert to costs. He notes that the money spent on building a yard would easily cover the extra cost of raising side walls by two feet, making the sty healthier. He also observes that cheap buildings similar to small barns have proved profitable for large-scale feeders, because they allow pigs to rest undisturbed between feedings and thus fatten more efficiently.

His chapter on present and future pig-keeping, and the pig calendar, suggest a systematic approach to the business. The inclusion of a chapter on curing pork shows that his interest extends beyond the live animal to the final product. Throughout, Spencer writes as a man who has balanced accounts as well as bred sows.

Spencer’s manual is best read as a working farmer’s notebook, not a scientific treatise. He does not pretend to settle the origin of the pig or to offer a single perfect system. Instead, he presents options—different breeds, different housing designs, different feeding routines—and gives his own verdict based on experience. Readers who want to understand early twentieth-century pig husbandry will find a wealth of specific detail, from the ideal height of a sty wall to the best way to ventilate a thatched barn.

There’s a certain patience in the way Spencer writes about his pigs—how warmth and clean air shaped their quiet thriving. I often find myself recalling that same tenderness when I close his pages and reach for A Treatise on Sheep: The Best Means for their Improvement, General Management, and the Treatment of their Diseases. — Reading Companion, as if both authors, years apart, whispered the same gentle truth about steady tending. That kinship is a soft thing to keep.
