粗放式管理条件下饲料营养对林麝麝香品质影响的研究

Study on the Effects of Feed Nutrient of on Musk Quality of Moschus berezovskii under Rough Management Conditions

为了了解粗放式管理条件下饲料营养水平与麝香品质的关系,2008—2010年间对山西省宝鸡市凤县一养麝场泌香期雄麝饲料调整前后麝香的品质进行了比较研究。结果表明,调整后泌香期雄麝饲料主要营养成分为粗蛋白22.5%、粗脂肪4.8%、粗纤维9.1%、灰分5.7%、无氮浸出物56.7%,Ca∶P为1∶1,饲喂调整饲料后,麝香的麝香酮含量为3.2%(标准≥2.0%)、总灰分为4.2%(标准≤6.5%)、含水量为51.4%(标准≤35.0%),麝香性状符合中国药典中的麝香标准指标,表明调整后饲料营养水平符合泌香期雄麝的营养需要。

In order to understand the relationship between feed nutrient level and musk quality under rough management, the musk quality of male Moschus berezovskii in a musk farm in Feng County of Baoji City, Shanxi Province before and after feed adjustment during 2008-2010 was compared. The results showed that the main nutrients of feed for male M. berezovskii in Musk secretion period were as followings： crude protein of 22.5%, crude fat of 4.8%, crude fiber of 9.1%, crude ash of 5.7%, nitrogen- free extract of 56.7%, Ca：P=1：1. After the feed adjustment, the content of muscone in musk was 3.2% （the standard muscone content/〉2.0% ）, the total ash content was 4.2% （the standard content of ash ~〈6.5% ） and the water content was 51.4% （the standard water content was 35.0% ）. The musk characteristics conformed to national musk standard in Chinese Pharmacopoeia, which indicated that the adjusted feed nutrient level could meet the nutrient requirement of male M. berezovskii in musk secretion period.
