Effects of YSE and EM on Growth Performance, Nutrients Digestibility and Serum Biochemical Indices of Growing Minks
摘要
Abstract
The present experiment was conducted to study the effects of YSE (yucca schidigera extract) and EM (effective microorganisms) on growth performance,nutrients digestibility and serum biochemical indices of growing minks.The twofactor cross experimental design was adopted.A total of 300 healthy growing minks at the age of 60 days were randomly divided into 6 groups with 20 replicates in each group.The addition amount of EM was 0,200 mg,and the addition amount of YSE was 0,200,400 mg.The pretest period lasted for a week and the experiment period lasted for two months.The results showed as follows:Both YSE and EM could improve body weight,and average daily gain of female minks during period Ⅱ (P＜0.05).During period Ⅰ,YSE improved crude fat digestibility and phosphorus digestibility (P＜0.05),reduced the ash digestibility and calcium digestibility (P＜0.05).During period Ⅱ,YSE improved calcium digestibility (P＜0.05),and EM improved ash digestibility and phosphorus digestibility (P＜0.05).The interaction of YSE and EM had effects on the phosphorus digestibility during period Ⅰ and Ⅱ (P＜0.05).YSE increased the serum TG and HDL concentration (P＜0.05),EM increased the serum TG concentration (P＜0.05).It could be concluded that 200 mg YSE and 200 mg EM per kilogram diet could improve growth performance of female minks,200 mg YSE increased phosphorus and crude fat digestibility as well as TG and HDL contents,chronic supplementation of 200 mg EM improved ash and phosphorus digestibility.关键词
