外源性环核苷酸对细毛羊产毛性能的影响

将28只1.5岁的新疆细毛羊育成母羊分为四组,Ⅰ,Ⅱ,Ⅲ组分别注射标准环核苷酸组合剂、自制环核苷酸组合剂和自制环核苷酸+育毛中药;Ⅳ组为对照组。分别测量了毛丛长、原毛量、毛纤维长、纤维直径及各种氨基酸含量等项指标。结果表明,连续观测365d以上,环核苷酸能显著提高细毛羊的产毛性能,以标准品组效果最佳,原毛量提高42.7％,纤维长增加43.9％。

The Effect of Exogenous Cyclic Nucleotides on the Wool Producing Performance of Finewool Ewes

Some 28 young ewes at the age of 1. 5 years old were divided into 4 groups. Groups I , II and III were injected with the mixture of the standard cAMP,and cGMP,the self-prepared mixture of cAMP and cGMP and the mixture of cAMP and cGMP plus wool developing Chinese herbal medicine respectively. Group VI was the control. Various kinds of indexes including staple length, grease wool output, wool fiber length and diameter and the contents of various amino acids were measured respectively. The results indicate that exogenous cyclic nucleotides(CNT) can significantly increase wool output and fiber length of young ewes after successive observations and measurements in over 365 days. The optimal effect was the standard group,whose wool output and fiber length were increased by 42. 7% and 43. 9% respectively.
