摘要
在蓝狐育成期的日粮中分别添加不同剂量的微生态制剂EM ,研究不同剂量的EM添加剂对幼狐生长发育、消化代谢及免疫机能的影响 .结果表明 ,EM添加剂能增强幼狐的采食量和平均日增重 ,Ⅲ组、Ⅳ组的平均日增重显著高于对照组 (P <0 .0 5 ) ;显著提高粗蛋白 (CP)、粗纤维 (CF)、矿物质元素Ca、P的消化率和净蛋白的利用率 (P <0 .0 5 ) ,且与剂量有关 ,Ⅲ组CP的消化率提高 8.2 1%、净蛋白的利用率提高 16 .2 7%、Ca、P的消化率分别提高 9.82 %、12 .13% .EM添加剂对粗脂肪 (EE)、无N浸出物 (NFE)的消化率无影响 (P >0 .0 5 ) ,能有效预防和治疗幼狐的腹泻和便血病 ,显著提高幼狐的免疫机能 (P <0 .0 5 ) ,提高幼狐的成活率 ,同时减少矿物质元素的排放量 .EM是一种高效、安全、环保型的饲料添加剂 ,可在毛皮动物养殖业中推广应用 .
Different doses of probiotics EM were added to the diets of blue fox in its growth phase to study the effects of EM additives on its growth, digestion metabolism and immune function. The results showed that with EM additives applied, the ingestion and average daily gains were increased remarkably ( P <0.05).The apparent digest rate of crude fibre,crude protein,mineral elements Ca,P and NPU could be increased ( P <0.05) and correlated with its dose, and the digest rates of the later four targets in group Ⅲ were increased by 8.21%,16.27%, 9.82 %,and 12.13%,respectively.EM additives could not increase the digest rate of ether extral and N free extract.Disease of diarrhoea and blood in stool could be prevented and cured, and immune function and the survival rate of fox in growth phase could be increased remarkably. EM, which a kind of efficient,safe and environmental protection additives, can be extended and applied in farming of fur animals.
