Genotype-By-Environment Interaction for Scrotal Circumference in Young Nellore Bulls Under Pasture and Feedlot Conditions and Its Correlation With Days to Calving. [PDF]
Anim GenetABSTRACT Scrotal circumference (SC) is a key reproductive indicator in beef cattle and an important predictor of male puberty and correlated female fertility. In this study, we evaluated young Nellore bulls raised under combinations of pasture and feedlot environments and modeled SC using a “double” reaction norm model. Additive genetic variance for SC
