|
摘要
本试验旨在研究不同饲料添加剂对育成期蓝狐生长性能、营养物质消化率及氮代谢的影响。试验选取40只健康公蓝狐,随机分成4组,每组10只。对照组饲喂基础日粮(未额外添加维生素和微量元素),Ⅰ组饲喂基础日粮+1%复合预混合饲料,Ⅱ组饲喂基础日粮+0.1%葡萄糖氧化酶,Ⅲ组饲喂基础日粮+1%复合预混合饲料+0.1%葡萄糖氧化酶。每个重复1只,预饲期7 d,试验期54 d。结果显示:1)试验Ⅰ组和Ⅲ组蓝狐100日龄体重显著高于对照组(P <0.05),与试验Ⅱ组差异不显著(P> 0.05);不同添加剂对蓝狐87日龄、116日龄、128日龄、140日龄体重及日平均采食量、平均日增重(ADG)、料重比(F/G)影响不显著(P> 0.05),但试验组的ADG均有高于对照组,F/G均有低于对照组的趋势。2)87～100日龄间,试验Ⅰ和Ⅲ组ADG极显著高于对照组(P <0.01),与试验Ⅱ组差异不显著(P> 0.05);101～116日龄间试验Ⅰ组和试验Ⅲ组极显著低于对照组(P <0.01),与试验Ⅱ组差异不显著(P> 0.05);不同添加剂对117～128日龄、129～140日龄间ADG影响不显著(P> 0.05)。3)试验Ⅰ组蛋白消化率显著高于试验Ⅱ组,但均与对照组和试验Ⅲ组差异不显著(P> 0.05);不同饲料添加剂对育成期蓝狐干物质、脂肪、碳水化合物和能量消化率均无显著性影响(P> 0.05)。4)试验Ⅰ组氮沉积显著高于对照组和试验Ⅱ组(P <0.05),与试验Ⅲ组差异不显著(P> 0.05);对N摄入、粪氮、尿氮、净蛋白利用率和蛋白质生物学价值无显著性影响(P> 0.05)。综上所述,从提高蓝狐生长性能和饲养成本考虑,基础饲粮(未额外添加维生素和微量元素)中添加1%复合预混合饲料能够促进营养物质吸收与利用,从而提高育成期蓝狐的生长性能。
This study was to evaluate the effect of different feed additives on growth performance, nutrients digestibility and N metabolism in blue fox during the growth period. This experiment selected 40 healthy male blue foxes which were randomly divided into 4 groups, basic diet(control group), basic diet(remove extra vitamins and trace elements)+1% compound premix(Group Ⅰ), basic diet+0.1% glucose oxidase(Group Ⅱ), basic diet(remove extra vitamins and trace elements) +1% compound premix + 0.1% glucose oxidase(Group Ⅲ) respectively.The experiment was 7 days for adaption and 54 days for trial period. The results showed as follows: 1) The 100-day body weight of the blue fox in Group Ⅰ and Group Ⅲ was significantly higher than that in the control group(P < 0.05), and there was no significant difference from Group Ⅱ(P > 0.05). There were no significant difference(P > 0.05) on the body weight of 87 day, 116 day, 128 day, 140 day old, ADFI,ADG and F/G. However, there was a trend that ADG of the experimental groups were higher than that of the control group, and F/G was lower than that of the control group. 2) The ADG of group I and group III on 87-100 days old was significantly higher than that of the control group(P < 0.01), but not significantly different from that of group II(P > 0.05). The ADG of group I and III on 101-116 days old was significantly lower than that of the control group(P < 0.01), but not significantly different from that of group II(P > 0.05). No significant effect on ADG between 117-128 days old and 129-140 days old(P > 0.05). 3) The CP digestibility in Group Ⅰ was significantly higher than that in Group Ⅱ, but there was no significant difference from the Control group and Group Ⅲ(P > 0.05). There was no significant effect on DM, EE,CC, GE digestibility of blue fox in the growth stage(P > 0.05). 4) Nitrogen deposition in Group Ⅰ was significantly higher than that in control group and Group Ⅱ(P < 0.05), and was not significantly different from that in Group Ⅲ(P > 0.05). No significant difference was found on N intake, FN, UN, NPU and BV(P > 0.05). Conclusion: considering the improvement of growth performance and feeding cost of blue fox, the addition of 1% compound premixed feed in the basic diet(no additional vitamins and microelements) can promote the absorption and utilization of nutrients, so as to improve the growth performance of blue fox during the growth period.
