Sire by environment interactions for growth traits in beef cattle

Abstract

Average region product-moment and rank correlations of weaning weight expected progeny differences of sires with ^20 expected progeny number in each of two regions of the United States Estimates of weaning weight genetic correlations of sire expected progeny differences of sires with progeny in each of two regions of the United States. .. Average region estimates of weaning weight genetic correlations of sire expected progeny differences of sires with progeny in each of two regions of the United States Within region of the United States variance component estimates for birth weight (kg?) Within region of the United States variance component. estimates for postweaning gain (kg?) Across regions of the United States variance component and heritability estimates for birth weight and postweaning gain (kgr)
