rearbreeding

Rearbreeding is not a standard term in formal breeding literature. It may be encountered as a colloquial or historical label with several different meanings depending on context. In general, it can refer to two broad ideas: (1) breeding programs that emphasize the development and provisioning of breeding stock, i.e., procedures for rearing animals intended for reproduction; or (2) targeted breeding to enhance hindquarters or rear-body traits in animals.

In the first interpretation, rearbreeding describes the care of young animals that will become breeding stock, covering aspects such as nutrition, health screening, socialization, and early genetic assessment to ensure robust adults. It may involve selecting dams and sires based on reproductive performance, disease resistance, and temperament, while maintaining genetic diversity.

In the second interpretation, rear-focused breeding aims to improve physical traits associated with the rear of an animal, such as hindquarter conformation, gait, and function. This approach can be used in breeds where movement and posture are important, but it risks exaggerated traits and reduced balance if not managed with comprehensive selection and welfare considerations.

Ethical and practical considerations include welfare, genetic diversity, and alignment with breed standards or industry regulations. As the term is not standardized, readers should seek clarification on the intended meaning when encountered in literature or discussions. Related concepts include selective breeding, line breeding, inbreeding, and breeding management.
