舍饲后不同时期滩羊裘皮性状的研究

目的]探讨滩羊生产性能的发挥与其饲养管理的长效性,为今后该品种的饲养管理提供理论依据。方法]研究了舍饲后不同时期滩羊裘皮性状。结果]在营养水平相近的条件下,与对照组(2003年,舍饲初期)相比,随着舍饲期的延长,试验组(2007年,舍饲后第5年)滩羊羔羊的初生重、二毛期体重、平均日增重、肩部毛长以及肩部弯曲数都有一定程度提高。经方差分析,二毛品质即肩部毛长、肩部弯曲数差异呈显著水平(P<0.05),初生重、二毛体重和日增重均呈极显著差异(P<0.01),花穗评分经方差分析差异不显著(P>0.05)。结论]舍饲饲养条件可提高滩羊羔羊裘皮特性。

Studies on Lamb Fur Characters of Tan Sheep at Different Periods after Yard Feeding

Objective] The production performance of tan sheep and the effectiveness of feeding and management were studied in order to provide the theoretical basis for the management of the sheep variety.Method] The lamb fur characters of tan sheep at different periods after yard feeding were studied.Result] The weight of birth,weight of 35-day,average daily gain,the fur length of shoulder and the crimps of shoulder of treatment group(2007 year,the fifth year after yard feeding) increased in various degree.Compared with control group(2003 year,the beginning of yard feeding),the fur length of shoulder and the crimps of shoulder were increased significantly(P<0.05),the weight of birth,weight of 35-day and average daily gain were increased significantly(P<0.01),and the mark of fur was not significant(P>0.05).Conclusion] The fur characters of tan sheep could be increased under the condition of yard feeding.
