海南5种经济作物副产物营养价值测定及鹅对其消化率研究
The Measurement of Nutritional Values of 5 Economic Crop Byproducts in Hainan and its Nutrient Digestibility to Geese
摘要
Abstract
To explore the effective utilization way of economic crop byproducts for feedstuff and subsequently resolve the contradiction between people and animals,we firstly measured the main nutritional components of 5 economic crop byproducts in Hainan and evaluated their comprehensive nutritional values by using subordination function method.We then investigated the nutrient digestibility of the 5 economic crop byproducts for geese.The results showed that:(1) The CP and EE contents of cassava stems and leaves,papaya stems and leaves,sugar cane tail leaves,mulberry stems and leaves and coconut meal were relatively higher,being 13.66％～22.36％ and 1.95％～5.26％ respectively;NDFand ADF contents were relatively lower,being 13.25％～33.26％ and 11.57％ ～29.63％ respectively.which can be used as the crude feed for herbirorous livestocks.(2) The comprehensive nutritional values of the 5 economic crop byproducts were ordered according to their subordination functional values as follows:coconut meal＞papaya stems and leaves＞cassava stems and leaves＞mulberry stems and leaves＞sugar cane tail leaves.(3) The CP and EE digestibility of these five economic crop byproducts were 39.46％ ～89.64％ and 78.33％ ～82.31％ respectively,the NDF and ADF digestibility were 20.19％～40.84％ and 19.60％～30.58％ respectively.关键词
