The Principles of Breeding

A clear‑headed guide for anyone who wants to turn everyday farm animals into more productive, profitable members of the herd. Drawing on the latest physiological insights, the book explains how heredity, nutrition, and environment combine to shape the traits of cattle, sheep, dairy cows and work horses. Its practical tone makes complex science feel approachable, offering step‑by‑step advice for selecting and caring for breeding stock.

The author frames animal husbandry as a business, urging farmers to define their own goals—whether that’s maximizing milk, wool, meat or draught power—and then match those aims to the right breeds and management practices. By comparing the challenges of American farms with those faced by English breeders, the text helps readers adapt proven techniques to local conditions, emphasizing the balance between short‑term returns and long‑term herd improvement.

Written in the mid‑19th century yet still relevant, the work serves as a handy reference for both newcomers and seasoned stock growers who seek a systematic, profit‑focused approach to breeding.
