Reducing bias in maintenance energy expected progeny difference by accounting for selection on weaning and yearling weights.

Journal of animal science - 1 May 2009

Williams J L, Garrick D J, Speidel S E

Abstract excerpt

Maintenance energy requirements of cattle can be predicted from published equations utilizing metabolic BW and milk production potential. Metabolic BW is a function of BW at a constant fat percentage or BCS. Pedigree and performance records can be used in random regression models to predict genetic merit for metabolic BW and milk production potentials. The purpose of this study was to present a methodology for...
