Abstract

The aim of the paper work is to optimize the population structure in a selection plan, according to  model developed by King (1961), which will be proposed to be applied for prolificacy improvement in Prolific Line Palas. The method used in this paper work is modeling, which exist in the most animal breeding scientifically papers. After the simulations, we observed that the most convenient variant was that which prefigure a weight of two groups by 70% (A) and 30% (B). This variant offer a genetic gain per generation by 0.452 additive standard deviations.
