Evaluation of maternal genetic effect using the pseudo individual weaning weight derived from litter weaning weight
By using the pseudo individual weaning weight that was derived from the litter weaning weight, the relationship coefficient between true and estimated breeding values (R) of the additive direct genetic effect showed a 40% decrease at the maximum, and the R for the additive maternal genetic effects was slightly reduced in the progeny generation. On the other hand, the R of the additive direct genetic effect showed a 25% decrease at the maximum, whereas the R of the additive maternal genetic effects slightly decreased in the dam generation. The results of this study suggest that it is possible to evaluate maternal genetic effects using the pseudo individual weaning weight that was derived from the litter weaning weight.
