| 摘 要： | 目的]研究螺旋藻粉和山药粉共同添加到犬粮中对幼犬增重、养分表观消化率和粪便质量的影响。方法]选用7月龄的贵宾犬幼犬14只,随机分为2组,每组7只。对照组饲喂基础饲粮,试验组饲喂基础饲粮+0.5%螺旋藻粉+1.0%山药粉。试验期为28 d。测定并比较不同组别幼犬日增重指标、养分表观消化率指标和粪便质量指标。结果]与试验开始时相比,试验结束时对照组幼犬体重增长了15%,试验组幼犬体重增长了18.34%,且试验结束时试验组幼犬体重显著（P<0.05）高于对照组;试验组幼犬的平均日增重比对照组高26.67%（P>0.05）。试验组幼犬对干物质、有机物、粗蛋白质和粗脂肪的表观消化率比对照组分别提高1.60%、1.02%、1.00%和0.24%,但差异均不显著（P>0.05）。对照组和试验组幼犬的粪便评分和粪便初水分含量均无显著差异（P>0.05）。结论]综上所述,在犬粮中添加0.5%螺旋藻粉和1.0%山药粉有助于促进幼犬的生长,对养分表观消化率和粪便质量无显著影响。

| Abstract: | Objective] To assess the effects of dietary supplementation of Spirulina platensis powder and yam powder on weight gain, apparent nutrient digestibility and fecal quality of puppies. Method]A total of 14 seven-month-old poodle puppies were randomly assigned into a control group and an experimental group. The control group （n=7） was fed with a basal diet, and the experimental group （n=7） was fed with the basal diet supplemented with 0.5% Spirulina platensis powder and 1.0% yam powder. The experiment lasted for 28 days. The indicators of weight gain, apparent nutrient digestibility and fecal quality of the puppies in the two groups were determined and statistically analyzed. Result]Comparing with the beginning of the experiment, the weights of the puppies in control group and experimental group were increased by 15% and 18.34% at the end of the experiment, respectively; the puppies in experimental group had significantly （P<0.05） higher weights at the end of the experiment compared with control group; the average daily gain of the puppies in experimental group was 26.67% higher than those in control group （P>0.05）. While the apparent nutrient digestibilities of dry matter, organic matter, crude protein and crude fat of the puppies in experimental group were elevated by 1.60%, 1.02%, 1.00% and 0.24% compared with control group, respectively, no significant differences （P>0.05） were observed. There were no significant differences （P>0.05） in fecal score and original moisture content between control group and experimental group. Conclusion] Dietary supplementation of 0.5% Spirulina platensis powder and 1.0% yam powder promotes the growth of puppies, but has no significant effects on apparent nutrient digestibility and fecal quality. |
