复合微生态制剂对苏牧白鹅雏鹅生长性能的试验研究

试验研究复合微生态制剂对雏鹅生长性能的影响。采用单因素随机设计,将160只1日龄健康苏牧白鹅仔鹅,随机分为4个处理,每个处理4个重复,每个重复10只,公母各半。0-3周龄雏鹅饲喂两种不同营养水平的饲料,观察其对雏鹅日增重、饲料报酬的影响。结果表明：雏鹅日增重、饲料转化率复合微生态制剂组显著高于不添加组。随着复合微生态制剂添加量的增加,肉鹅的日增重和日采食量均上升的趋势,料重比呈下降后的趋势,其中试验3组的日增重与采食量最高,但与对照组差异显著,与试验1组、试验2组差异显著（P〈0.05）;试验1组与试验2组差异不显著（P〉0.05）;料重比的变化趋势与平均日增重相同。

Experimental Study on Compound Microecological Preparation to Su-Mu White Geese Growth Performance

The experiment is a study about the effect of compound probiotics on growth performance of geese. 160 one-day-old health Su Mu white goose were selected by a single factor randomized design and four treatments with four replicates of 10 were randomly divided. Two different levels of nutrition feed were fed on 0-3 week-old goslings . The effect of gosling average daily gain （ADG） and feed conversion ratio were observed. The results showed that goslings daily gain, feed conversion ratio of compound probiotics group were significantly higher than control group. Goslings ADG and daily feed intake were presented a rising tendend and feed to gain ratio showed a decreasing trend with the increase of composite probiotics amount. The daily gain and feed intake of group 3 was highest, significant difference from the control group, group 1 and group 2（P 0.05）. Group 1 and group 2 were not significantly different （P 0.05）. Feed gain ratio trends and average daily gain were same.
