Data about reproductive performances of sows from a hyperprolific line in a breeding herd and those of sows in the multiplication herd were collected in order to evaluate the effect of the hyperprolific line on the litter size in the multiplication herd. Mixed linear models in SAS for Windows 9.1.2. were used for statistical analyses of the data collected from the first to the fifth litters. Our results indicated that the litter size (total number of born piglets, number of piglets born alive, number of weaned piglets) was not significantly influenced by the use of the hypeprolific line.
