The trait in this research include birth weight （BW）, 3 （W3）, 6 （W6）, 9 （W9）, 12 （W12） months weight, fleece weight （WF） （as production traits）, body length（BL）, size of femur（F）, thorax（TX）, testis（TS）, height of lumber（L） and shoulder（SH） （as morphological traits）. Variance components, least square means and standard error of production and morphological traits were estimated and environmental factors （including effects of year of birth, season, sex, type of birth and age of dam） were studied with GLM procedure of SAS 9.1 software. The results showed that the all environmental factors have significant effect, male lambs weight more than females, and twins were more performance than single. Production and apparent performance characteristics of phenotypic traits was different in year of birth, maternal age, season. This study shows that Macoie sheep breed at the various management environment have suitable performance and genetic potential.展开更多
