Measuring Real-World Benefits Of Breeding Programs

摘要

With acctirate evaluation of production data, it is possible to statistically disentangle genetic and environmental effects on growth rate without experimental grow-out in controlled environments. Pedigree records are not required, although each generation stocked must be identified. In general, benefits from genetic increases in growth rate result from better farm environments. Breeding programs should focus selection on genes expressed favorably in the environment that most affect farm profit.
