Covariances among sire by breed group of dam interaction effects in multibreed sire evaluation procedures.
In multibreed populations, bulls need to be evaluated for additive and nonadditive genetic effects. When the nonadditive genetic effects associated with a bull are defined as sire x breed-group-of-dam interactions, they can be expressed as linear combinations of interactions between alleles of one or more breeds at one or more loci. If these specific allelic interactions are assumed to be indep...

متن کاملCharting the Road Map for Long-Term USDA Efforts in Agricultural Animal Genomics: Summary of the USDA Animal Genomics
Agricultural animal research has been immensely successful over the past century in developing technology and methodologies that have dramatically enhanced production efficiency of the beef, dairy, swine, poultry, sheep, and aquaculture industries. Most of this research effort has been conducted within the broad disciplines of genetics, physiology, and nutrition, but has become increasingly nar...
متن کاملUnrelieved pain and distress in animals: an analysis of USDA data on experimental procedures.
Pain and distress are core issues in the field of animal experimentation and in the controversy that surrounds it. We sought to add to the empirical base of the literature on pain and distress by examining government data on experimental procedures that caused unrelieved pain and distress (UPAD) in animals. Of the species regulated by the U.S. Department of Agriculture (USDA), most of the appro...
