Optimization of population size and structure in an offspring selection plan for milk production traits of rams from Palas milk line.

Abstract The aim of this paper is the optimization of population size and structure in an offspring selection plan of rams, according to Robertson and Rendell model for bovines (1951), which will be propose for implementation in Palas Milk Line for genetic increase of milk production traits. 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 an active population size of 400 females and from those 55% represented elite group and 45% testing group.
