Application research of mixed silage feed with potato stems and leaves and corn stalks in fattening mutton sheep
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.
