The influence of lactation length, weaning to conception interval and reduction in the contemporary group size on the prediction of breeding values for litter size in pigs is analized. The inclusion in the prediction model of the effects mentioned above does not entail relevant variations either in the ranking of the animals or in the estimates of genetic trend. The loss of expected response caused by the omission of these effects in the model is always lower than 2 %.
