• Genomic reaction norm models exploiting genotype × environment interaction on sexual precocity indicator traits in Nellore cattle

    10 days ago - By Animal Genetics

    Summary
    Brazilian beef cattle are raised predominantly on pasture in a wide range of environments. In this scenario, genotype by environment interaction is an important source of phenotypic variation in the reproductive traits. Hence, the evaluation of G×E interactions for heifer's early pregnancy and scrotal circumference traits in Nellore cattle, belonging to three breeding programs, was carried out to determine the animal's sensitivity to the environmental conditions. The dataset consisted of 85 874 records for HP and 151 553 records for SC, from which 1800 heifers and 3343 young bulls...
