Abstract

Optimum reproduction is critical to the success of any livestock enterprise. The existence of breed genotype x environment and, particularly, of mating system x environment interactions for components of reproduction have not been thoroughly investigated. Should important genetic x environment interactions of these sorts exist, choices of mating systems and breed combinations for specific physical or managerial environments would be affected. In this study, both genotype x environment and mating system X environment interactions for reproductive traits are examined. Environmental variables were years and systems of pastoral management in the same area, and genotypes were all possible straight- bred and crossbred combinations among three mutton breeds.
