Abstract

The researches were effectuated in a selection farm, in a swine pattern line utilized as a generator of commercial hybrid father obtained in this unit. The national program of swine improvement takes in account that genetic evaluation of selection candidates it’s made based on BLUP methodology and selection effect estimation it’s made by difference between average breeding values of candidates by successive generations. In analyzed population, the genetic evaluation it’s made based on individual performance. Analyzing selection difference and selection ratio we can draw interesting   conclusions related with breeding work efficiency.
