Indirect Genomic Predictions for Indicine Cattle Breeds With SNP Effects From a Multi-Breed Genomic Evaluation.

ABSTRACT: Indirect predictions (IP) are used for young genotyped animals that lack phenotypes (of their own or from progeny) or are from commercial herds. The former can be left behind because they do not contribute to the official genomic evaluations. The latter are often excluded from the evaluations because they are not registered and may not have pedigree information. Including such animals could result in inflated and biased genomic breeding values (GEBV). In Brazil, pedigree, phenotype and genotype information is scarce for important breeds like Brahman, Guzerat, and Tabapua, while the Nellore breed has a substantial amount of information. IP for young animals of these breeds based on a larger reference population could enhance genomic selection accuracy. Our objective in this study was to com
