非遗传因素对西门塔尔牛主要经济性状的影响
Effects of non-genetic factors on main economic traits of Simmental cattle
摘要
Abstract
In order to investigate the influence of non-genetic factors on main economic traits of Simmental cattle,the production performance record of Xinjiang Hutubi cattle farm from 1989 to 2014 years were adopted,a total of 1492 Simmental cattle,effects of the factors including parity differences,calving years,calving seasons,age of calving on the main economic traits,e.g.305 days of milk yield,body height,body length (hard),body length (soft),chest girth,circumference of abdomen,rump width,rump length,leg circumference,cannon circumference,body weight and type classification of Simmental cattle were analyzed by least square analysis.The results showed that:different parity,calving year and age of calving had a significant effect on the main economic traits in Simmental cattle (P＞0.05).While different calving seasons had a significant effect on the 305 days of milk yield,body height,chest girth,rump width,rump length,leg circumference,cannon circumference,body weight and type classification (P＜0.01),it had no significant effect on body length(hard),body length(soft),circumference of abdomen (P＞0.05).This study provided a theoretical basis for Simmental cattle breeding value estimation and breeding objectives program.关键词
