| Outline of Final Research Achievements |
To determine the most suitable restricted selection method, a stochastic Monte-Carlo computer simulation program for predicting response to selection and a program for restricted BLUP selection were developed. These programs were used to compare several restricted BLUP methodologies, that is, restricted index selection (control), BLUP imposing the same restriction on all animals (AR-BLUP), and imposing only some animals (PR-BLUP) in a population. Response to selection and inbreeding on PR-BLUP were more desirable than on AR-BLUP. In addition, an optimum calculating procedure for relative weights of breeding values of selected traits for estimating aggregate breeding values was considered for restricted selection to achieve desired genetic changes.
