Book Description
Excerpt from Animal Breeding Breeding a Science and an Art - Animal breed ing is at once a science and an art. It is a science in so far as it discovers and systematically arranges the truths and principles which relate to the improve ment of live stock. The value of in-and - in breeding, for instance, as a quick means of improvement illus trates such discovery. (see Chapter X.) It does not appear to have been known to the ancients. If it were thus known the knowledge was subsequently lost. The systematic arrangement of the truths and principles which relate to the science is yet far from complete, and it may be added, that many of these truths and principles are not yet understood. It is an art in so far as it successfully uses those principles in effecting improvement. The importance, there fore, of understanding the principles which make improvement possible will be at once apparent, since, until so understood, they cannot be turned to profit able account.

Book Description
First published in 1943, “Animal Breeding Plans” contains a detailed guide on animal breeding designed for students with experience of genetics, embryology, breeds, and stock judging. It aims to furnish the reader with a clear understanding of the means available for improving the heredity of farm animals, especially what each possible method will or will not do well. Highly recommended for modern farmers and animal breeders. Contents include: “Origin and Domestication of Farm Animals”, “Consequences of Domestication”, “Beginning of Pedigree Breeding Methods in the United States”, “History of Animal Breeding Methods in the United States”, “Relation of the Breed Association to Breed Improvement”, “Genetic Principles in Animal Breeding”, “Mendelian Basis of Inheritance”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on farming.
