Related individuals often have similar phenotypes, but this similarity may be due to the
effects of shared environments as much as to the effects of shared genes. We consider here …

Data from Dutch Landrace sows were used to estimate genetic parameters for reproduction
traits in the first six parities. Analyses were performed with DFREML using a model with …

A total of 66,620 records from the first six parities for number of piglets born alive (NBA) from
20,120 Landrace sows and 24,426 records for weight (WT) and backfat thickness (BT) at …

The aims of this study are to estimate variance components of litter size and kit survival rate
and estimate genetic correlations of litter size and kit survival rate with dam's juvenile body …

Improvement of litter size in pigs through selection was considered a difficult task in the past.
Low heritability, negative correlation between direct additive genetic and maternal effect …

Variance components for number of pigs born alive (NBA) were estimated by Gibbs
Sampling using an animal model for the additive genetic maternal and paternal effect. The …

This study aimed to analyse genetic background of variation in reproductive performance
between parities of a sow and to investigate selection strategies to change the “parity curve” …

We estimated genetic parameters for number born alive (NBA) from the first to the seventh
parities in Landrace and Large White pigs using three models. Analyzing 55,160 farrowing …

Genetic parameters were estimated for number of pigs born alive (NBA), adjusted litter
weaning weight (ALWT), and the interval from weaning to first service (W2E) using 2002 …

Increased milk production due to high litter size, coupled with low feed intake, results in
excessive mobilization of sow body reserves during lactation, which can have detrimental …
