摘要: [目的]为了研究酵母培养物对鹌鹑生长性能、免疫功能和肠道菌群的影响。[方法]试验选取1日龄朝鲜龙城系鹌鹑720羽,随机分4个处理组,每组6个重复,每个重复30羽。对照组饲喂基础日粮,试验Ⅰ组、Ⅱ组和Ⅲ组分别在基础日粮的基础上添加0.1%、0.15%和0.2%的酵母培养物,试验期42d。[结果]结果表明:试验Ⅱ组和Ⅲ组均能显著提高鹌鹑1-21d、22-42d和1-42d平均日增重,降低料重比。显著提高21d和42d鹌鹑法氏囊指数和42d鹌鹑胸腺指数、脾脏指数。试验Ⅰ组、Ⅱ组和Ⅲ组均能显著降低21d鹌鹑盲肠中大肠杆菌、沙门氏菌数量,试验Ⅱ组和Ⅲ组能显著增加乳酸杆菌数量,且试验Ⅰ组和Ⅲ组组间差异亦显著;试验Ⅰ组、Ⅱ组和Ⅲ组均能显著降低42d鹌鹑盲肠中大肠杆菌、沙门氏菌数量,显著提高乳酸杆菌数量,试验Ⅰ组和Ⅲ组组间差异均显著。[结论]说明酵母培养物提高鹌鹑的生产性能和免疫功能,改善肠道的菌群结构。适宜添加量为0.15%。

Abstract: The aim is to investigate the effects of yeast culture on growth performance, immune function and intestinal flora of quails. 720 one-day-old healthy quails of Korean Dragon were chosen and randomly divided into four groups, including control group, test group I (basic diet + 0.1% yeast culture), test group II (basal diet + 0.15% yeast culture) and test group III (basic diet + 0.2% yeast culture), 6 replicates were set for each group and each repeat had 30 chickens, and the test period was 42 days. The results showed that group I, group Ⅱ and group Ⅲ could significantly increase ADG of quails and reduce the F/G of quails in 1-21 d, 22-42 d and 1-42 d, and the index of fabricius bursa in 21 d and 42 d quails and the indexes of thymus and spleen in 42 d quails significantly increased. All group Ⅰ, group Ⅱ and group Ⅲ could markedly decrease the numbers of Escherichia coli and Salmonella in cecum in 21 d quail, and group Ⅱ and group Ⅲ could obviously increase the number of Lactobacillus in cecum, and the difference between group Ⅰ and group Ⅲ was also significant. Group Ⅰ, group Ⅱ and group Ⅲ could also markedly decrease the numbers of Escherichia coli and Salmonella in cecum and obviously increase the number of Lactobacillus in 42 d quails, there was significant difference between group Ⅰand group Ⅲ. It indicated that the growth performance and immune function of quails could be increased and the structure of intestinal flora could be improved by feeding yeast culture. The appropriate dosage yeast culture was 0.15%.
