Abstract
Eight selection indexes for weanling beef calves were developed and compared. These were based on daily gain from birth to weaning, 203-day weight, and type score. Selection on the basis of an index combining daily gain and type or weaning weight and type in the best linear equation was concluded to be preferable to selecting on the basis of either growth or type singly. Estimates of heritabilities, genetic and phenotypic correlations, and economic values were calculated.This publication has 6 references indexed in Scilit:
