Abstract

This study compared predictions of selection response, genetic variance, accuracy of selection, male and female selection differentials, and inbreeding levels from a deterministic model to results from stochastic simulation of index selection in closed nucleus breeding schemes for beef cattle. Deterministic predictions of response were generally within 1% of stochastic results. It was concluded that deterministic models provide accurate predictions for evaluating expected selection response from alternative closed nucleus breeding structures.
