季节对不同品种种公牛精液品质的影响
Effects of Season on Semen Quality of Different Breed Bulls
摘要
Abstract
To explore seasonal influence on the bull semen quality from different breeds,the annual results of frozen semen production from Chinese Holstein,Simmental and Japanese Black Cattle,were collected and analysed.The results showed that the standard rate of fresh semen from Chinese Holstein bulls in spring and winter were higher than in summer (P＜0.05),the standard rate was significantly higher in winter than in summer(P＜0.01).The survival rate of frozen semen was higher in winter and autumn than in summer(P＜0.05) and that was significantly higher in autumn than in spring and summer(P＜0.01).The ejaculation semen volume of all breeds in spring and winter was higher than in autumn(P＜0.05) and that was significantly higher in spring than in autumn(P＜0.01).The density of semen from all breeds in spring,autumn and winter was higher than in summer.The standard rate of Simmental fresh semen in spring reached the highest level and that was higher in spring than in summer and autumn(P＜0.05).The survival rates of fresh and frozen semen of Japanese black cattle was the best in winter than the other three seasons and there was no difference about ejaculation semen volume among the seasons(P＞0.05)and the semen density was higher in summer than in spring(P＜0.05)and significantly higher than in autumn and winter(P＜0.01).In conclusion,the standard rates of fresh and frozen semen were better in spring and winter than in autumn and summer and the semen quality of beef cattle was superior to that of dairy cow and the semen quality of Simmental was better than that of Japanese black cattle.关键词
