不同配方对育成期蓝狐生长性能和营养物质消化率的影响

Effect of Different Feed Formulations on Growth Performance and Nutrient Digestibility of Blue Fox in Breeding Period

[目的]旨在探讨不同配方对育成期蓝狐生长性能和营养物质消化率的影响。[方法]采用单因子随机试验设计,选择育成期蓝狐60只(公母各半),分成3组(Ⅰ组、Ⅱ组和Ⅲ组),分别饲喂3种不同配方饲粮。[结果]Ⅲ组蓝狐平均日采食量显著高于Ⅰ组和Ⅱ组;Ⅲ组公蓝狐末重显著高于Ⅱ组,Ⅲ组母蓝狐末重和平均日增重显著高于Ⅱ组;Ⅲ组母蓝狐料重比显著高于Ⅰ组和Ⅱ组,公蓝狐料重比差异不显著;Ⅲ组蓝狐脂肪消化率显著高于Ⅱ组。[结论]Ⅲ组配方(干物质33.89%、粗蛋白31.14%、粗脂肪18.23%)更适宜育成期蓝狐的生长和营养物质的消化。

[Objective]The aim was to study the effects of different formulations on the growth performance and nutrient digestibility of the blue foxes during the breeding period.[Method]The trial has adopted one-factor completely random design. A total of 60 healthy blue foxes(half male and female) in the breeding period were randomly divided into three groups (group Ⅰ, group Ⅱ and group Ⅲ), and fed three different formula diets.[Result]The average daily feed intake of group Ⅲ blue fox was significantly higher than that of group Ⅰ and group Ⅱ;the final weight of male blue foxes in group Ⅲ was significantly higher than that of group II, and the average daily gain of female blue foxes in group Ⅲ was significantly higher than those of group Ⅱ;ratio of feed to gain(F/G) of female blue fox in group Ⅲ was significantly higher than that of other two groups, there were no significant effect on male blue fox among three groups. Fat digestibility of group Ⅲ was significantly higher than that of group Ⅱ.[Conclusion]The formulation of group III (dry matter 33.89%, crude protein 31.14%, crude fat 18.23%) was more suitable for the growth and the nutrients digestion of blue fox during the breeding period.
