玉米秸秆青贮饲料品质分析及对波宜杂交山羊生产性能的影响

Quality Analysis of Corn Stalk Silage and Its Effects on Production Performance of Boer and Yichang White Crossbred Goats

本文对玉米秸秆青贮饲料和全株玉米青贮饲料的品质进行了比较,并分析了2种饲料对波宜杂交山羊生产性能的影响。结果表明,玉米秸秆青贮饲料中的中性洗涤纤维含量显著高于全株玉米青贮饲料,而酸性洗涤纤维含量显著低于全株玉米青贮饲料。全株玉米青贮饲料、玉米秸秆青贮饲料pH值分别为3.85、4.13,综合显示全株玉米青贮饲料营养价值优于玉米秸秆青贮饲料。饲喂全株玉米青贮饲料的山羊增重量显著高于玉米秸秆青贮饲料,呈极显著差异,从综合养殖效益分析两者之间差异不明显。玉米秸秆青贮饲料能满足波宜杂交山羊一般性生长需求,其价格低廉、营养品质较好,适合季节性饲草短缺地区推广应用。

In this paper,the quality of corn stalk silage and whole plant corn silage were compared,and the effects of two kinds of feeds on the production performance of Boer and Yichang white crossbred goats were analyzed.The results showed that the content of neutral detergent fiber in corn stalk silage was significantly higher than that in whole plant corn silage,while the content of acid detergent fiber in corn stalk silage was significantly lower than that in whole plant corn silage.The pH values of whole plant corn silage and corn stalk silage were 3.85 and 4.13,respectively,which comprehensively showed that the nutritional value of whole plant corn silage was better than that of corn stalk silage.The weight gain of goats fed whole plant corn silage was significantly higher than that of corn stalk silage,showing an extremely significant difference,but the difference between the two was not obvious from the analysis of comprehensive breeding benefits.Corn stalk silage can meet the general growth needs of Boer and Yichang white crossbred goats,with low price and good nutritional quality,and is suitable for promotion and application in areas with seasonal forage shortages.
