It was found that selection on high litter size was shown to decrease the mean piglet birth weight and to increase the within-litter variability of birth weight. These changes in the birthweight traits cause an increase in the number of stillborn piglets and in the losses from birth to weaning. Therefore, selection on litter size should be accompanied by selection on mortality traits and\/or birth-weight traits. On the basis of the estimated heritabilities and genetic correlations, pre-weaning mortality and the minimal birth<br \/>\nweight in the litter are proposed as potential traits for selection against piglet mortality.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Using a large data set with nearly 40,000 weighed piglets, the aim of the present study is to investigate the question to what extend measures of the distribution of the birth weight within litter are heritable.
