Effects of fermented cassava residue on growth performance,serum biochemical indexes,and economic benefits of Hu sheep
The experiment aimed to explore the effects of adding different amounts of fermented cassava residue to the feed on the growth performance,serum biochemical indexes,and economic benefits of Hu sheep.A total of 48 weaned Hu sheep were randomly divided into four groups,with 12 replicates per group and one sheep per replicate.The sheep in each group were fed with feed containing 0(control group),10％,20％,and 30％fermented cassava residue.The preliminary trial period was seven days,and the formal experimental period was 60 days.The results showed that compared to the control group,the final weight,total weight gain,and average daily weight gain of the 20％fermented cassava residue group were significantly increased(P＜0.05),and the feed to gain ratio was significantly decreased(P＜0.05),the content of total protein and albumin in serum was significantly increased(P＜0.05),and the content of urea nitrogen was significantly decreased(P＜0.05).The activity of glutamic-oxaloacetic transaminase in the serum of the 10％and 20％fermented cassava residue groups was significantly decreased(P＜0.05),the content of creatinine in the 10％and 30％fermented cassava residue groups was significantly increased(P＜0.05),the content of uric acid in the 20％and 30％fermented cassava residue groups was significantly increased(P＜0.05).Compared with the control group,the weight gain income of Hu sheep in each fermented cassava residue group increased by 10.68％,23.76％,16.57％,and the breeding profits increased by 10.36％,36.92％,14.99％,respectively.The results show that 20％fermented cassava residue in the diet can improve the production performance of Hu sheep,and the economic benefit of breeding is good.
