Effect of L-lysine Added in Diluent on the Fresh Semen Quality of Dorper Sheep

In order to explore the effect of different L-lysine levels added in semen dilution on the fresh Dorper sheep quality stored at liquid state,3 health Dorper ram were used to collect semen which were equal-packaged and added to solution containing different levels (0,0.1,0.2,0.3,0.4 and 0.5 g) L-lysine in 120 mL diluent and at 0,6,24,30,48,54,72 and 78 h,the sperm motility,membrane integrity and acrosome integrity were detected.The results showed that the sperm motility in groups added 0,0.1 and 0.2 g L-lysine were higher than other groups,and that in 0.4 and 0.5 g L-lysine groups decreased faster than other groups;The sperm motility in 0.5 g L-lysine group reduced to 0 at 30 h,and it reduced to 0 at 48 h in the group added 0.4 g L-lysine;The effective survival time and survival index in the group added 0.1 g L-lysine was higher than other groups (P< 0.05);The membrane integrity of 0.1 g group was the highest,that had no significant difference with control group from 0 to 54 h (P >0.05),while after 72 h the two groups had significant differences (P< 0.05).The membrane integrity in 0.4 and 0.5 g groups were the worst,and that was significant different with other groups (P< 0.05);The acrosome integrity of 0.1 g group was the highest which had no significant difference with control group (P >0.05),0.4 and 0.5 g groups were the worst,the difference between them was not significant (P >0.05),while was extremely significant difference with other groups except for 0 and 6 h (P< 0.01).The results suggested that dilution added a high concentration of L-lysine could inhibit sperm quality,when the count of L-lysine was more than 0.2 g,sperm quality was significantly decreased,adding 0.1 g L-lysine could improve Dorper sheep fresh sperm quality stored at liquid state.     

一起引进杜泊羊暴发传染性胸膜肺炎的诊治及体会

黑头杜泊羊与和丰本地绵羊杂交后代羔羊生产性能及肉品质研究

为了客观评价黑头杜泊羊与和丰本地绵羊杂交后代羔羊的生产性能和肉品质,挑选杂交后代羔羊和本地绵羊羔羊各60只作为研究对象,测定其生产性能和肉品质的各项指标.结果表明:初生、1月龄杂交后代羔羊的体重显著高于本地绵羊羔羊(P<0.05),2月龄、3月龄、4月龄杂交后代羔羊的体重均极显著高于本地绵羊羔羊(P<0.01).4月龄...     

湖羊、小尾寒羊与肉用杜泊羊杂交试验

以引进优质杜泊绵羊为父本与湖羊和小尾寒羊进行杂交,湖羊和小尾寒羊母羊群采用激素诱导同期发情后,以杜泊绵羊鲜精进行人工授精。分析不同羊群受胎率、产羔率以及F1代杂交羔羊生长速度与体尺变化。结果表明 湖羊和小尾寒羊群体受胎率和产羔率没有显著差异（P﹥0.05） 杜湖杂交羊与湖羊初生重、1月龄、2月龄体重差异不显著,3月龄、6月龄、日增重差异极显著（P﹤0.01） 杜寒杂交羊与小尾寒羊初生重差异不显著,1月龄、2月龄、3月龄、6月龄、日增重差异极显著（P﹤0.01） 杜湖杂交羊与杜寒杂交羊初生重差异极显著（P﹤0.01）、1月龄、6月龄体重和日增重差异显著（P﹤0.05）,2月龄和3月龄体重差异不显著 湖羊与小尾寒羊初生重差异不显著,1月龄、6月龄体重和日增重差异显著（P﹤0.05）,2月龄、3月龄体重差异极显著（P﹤0.01）。初步杂交试验认为杜泊羊与湖羊或小尾寒羊杂交均可分别作为理想的父、母本组合,用于进一步培育优质肉用杂交绵羊新品系（种）研究。
