林麝放牧区野生饲用植物叶营养成分的综合分析

在测定林麝（Moschus berezovskii）喜食野生植物叶的常规养分及矿物质元素的基础上，利用简单线性相关、营养类型及聚类分析，对植物叶成分含量进行了综合分析与归类，以期明析24种野生植物叶的养分含量特点和营养类别，为林麝日粮中青粗料的合理搭配及饲草资源的开发提供参考依据。结果表明，24种植物叶粗纤维(CF)含量均能满足林麝需要；粗蛋白(CP)含量仅构树（Broussonetia papyrifera）、葎草（Humulus scandens）及野桑（Morus alba）能满足其需要；钙含量均超过需要；磷含量部分超过需要；杜仲（Eucommia ulmoides）、苦木（Picrasma quassiodes）、葎草（Humulus scandens）及木姜子（Litsea pungens）等的钙磷比低于7.00，铁、锰含量超过林麝营养需求，铜、锌不足；灰分（Ash）与CP呈显著正相关（P＜0.05），Ash与无氮浸出物（NEF）呈极显著负相关(P＜0.01）， CF与NEF呈显著负相关（P＜0.05)， CP与NEF呈极显著负相关(P＜0.01）；金钱槭（Dipteronia sinensis）、野桑、木姜子C/N均小于3.75，属于N型，葛萝槭（Acer grosseri）C/N为7.27，属于C N型，蛇葡萄、构树、葎草属于灰分 N型，金银忍冬（Lonicera maackii）、铁箍散（Schisandra propinqua var. sinensis）、丛花南蛇藤（Celastrus rosthornianus var.loeseneri）属于NC 灰分型，其余属于N C型；按常规养分含量可将植物叶分为6类，按矿物质元素含量可将植物叶分为7类。

Research on comprehensive analysis and content of nutritive ingredients in plant leaves for forest musk deer

Based on determinating ingredients of plant leaves, used a simple linear correlation, nutritive type and cluster analysis to classify separately according to nutritive ingredients and partial minerals contents. This study expected to provide references of mixed ration for rasing forest musk deer according to plant leaves nutrient trait. The results indicated that crude fiber satisfy the nutrition demand of the forest musk deer, crude protein contents of Broussonetia papyrifera，Humlus scandens and Morus alba were also satisfied the demand. The calcium content surpassed the demand, while some kinds of plant leave phosphorus content surpassed the demand.The ratios of calcium to phosphorus of Eucommia ulmoids,Picrasma quassiodes，H. scandens and Litsea pungens were less than 7.00, the iron and manganese contents surpassed the demand, the copper and zinc canno satisfy. ASH and CP had significant positive correlation(r=0.610 8), ASH and NEF had significant negative correlation (r=0.684 2), CF and NEF had significant negative correlation(r=0.600 4), CP and NEF had significant negative correlation(r=0.793 2). The nutrition ratio (C/N) of Dipteronia sinensis and M.alba, L.pungens was lower than 3.75, belonged to the N type. The nutrition ratio (C/N)of Acer grosseri was 7.27, belonged to the C N type, Ampelopsis bodinieri, H.scandens and B.papyrifera were belonged to ash N type, Lonicera mackii,Schisandra propinqua and Celastrum rosthornianus belonged to NC ash type, the rests belonged to N C type.The plant leaves have been divided into 6 kinds according to the conventional nutrient content, and also may be divided into 7 kinds according to the mineral content.
