Continuous genetic evaluation of on farm and station tested pigs for production and reproduction traits in France

A continuous genetic evaluation system has been implemented in France to estimate breeding values of on farm and station tested pigs for production and reproduction traits using a multiple trait animal model. A weekly evaluation is performed using data for production traits. A genetic evaluation for litter size is performed independently every month. Within herd estimated breeding values are computed by combining results from the last national evaluation and the performance of on-farm tested young pigs. Breeding objectives, models used, and details on both genetic evaluations are described.
