摘要
试验旨在研究马铃薯茎叶与玉米秸秆混合青贮饲料在肉羊育肥中的应用效果。将80%马铃薯茎叶与20%玉米秸秆混合,制作青贮饲料,使用V-Score评分体系对混合青贮饲料进行品质评价。选取4月龄小尾寒羊40只,随机分为2组,每组20个重复。对照组饲喂玉米秸秆青贮饲料,试验组饲喂马铃薯茎叶与玉米秸秆混合青贮饲料。结果显示,混合青贮饲料品质的综合评定结果为良好。试验组育肥羊的平均日增重高于对照组(P<0.01)。研究表明,马铃薯茎叶和玉米秸秆混合制作青贮饲料可行,混合青贮可以有效改善青贮饲料的营养价值,提高了育肥羊的生长性能。
The experiment aimed to study the application effects of mixed silage feed with potato stems and leaves and corn stalks in fattening mutton sheep.Silage feed was prepared by mixing 80% potato stems and leaves with 20% corn stalks,and the quality of the mixed silage feed was evaluated by the V-Score scoring system.Forty 4-month-old Small-tail Han sheep were randomly divided into two groups,with 20 replicates in each group.The control group was fed a corn stalk silage feed,and the experimental group was fed a mixed silage feed of potato stems and leaves and corn stalks.The results showed that the comprehensive evaluation of the quality of mixed silage feed was good.The average daily weight gain of the experimental group was higher than that of the control group(P<0.01).The study indicates that making silage feed by mixing potato stems and leaves with corn stalks is feasible.Mixed silage can effectively improve the nutritional value of silage feed and increase the growth performance of fattening sheep.
