摘　　要：本试验旨在研究饲粮添加复合益生组合物对猫生长性能、养分表观消化率、免疫功能、抗氧化能力、毛发健康以及肠道菌群的影响。试验选取日龄、体重接近的健康成年英国短毛猫16只,随机分为2组,每组8只(单笼饲喂)。对照组饲喂基础饲粮;试验组饲喂在基础饲粮中添加复合益生组合物(由凝结芽孢杆菌、多种来源的膳食纤维以及ω-3与ω-6不饱和脂肪酸按1∶3比例复合而成)的饲粮,每100 g猫粮含2×10^(7) CFU凝结芽孢杆菌、1.15 g膳食纤维和4 g不饱和脂肪酸。预试期2周,正试期6周。结果表明:1)与对照组相比,试验组猫日采食量、粪便评分、粪便pH和体重变化均无显著差异(P>0.05)。2)与对照组相比,试验组猫各养分表观消化率、血常规指标和血清生化指标均无显著差异(P>0.05)。3)与对照组相比,试验组猫血清免疫球蛋白M(IgM)含量和超氧化物歧化酶(SOD)活性显著提高(P<0.05)。4)与对照组相比,试验组猫毛发评分呈上升趋势(P=0.078)。5)与对照组相比,试验组猫肠道菌群α多样性指数无显著差异(P>0.05),但特有的肠道菌群数目明显增多。与对照组相比,在门水平,试验组变形菌门(Proteobacteria)相对丰度显著提高(P<0.05);在属水平上,试验组Catenibacterium相对丰度较有提高趋势(P=0.081)。综上所述,饲粮添加复合益生组合物可以提高猫血清IgM含量和SOD活性,同时改善肠道菌群结构和毛发评分,对提升猫的整体健康状况具有积极作用。This experiment was conducted to investigate the effects of dietary compound prebiotic composition on growth performance,nutrient apparent digestibility,immune function,antioxidant capacity,hair health and intestinal microflora of cats.Sixteen healthy British shorthair cats with similar body weight and age were randomly divided into 2 groups with 8 cats in each group(single cage feeding).Cats in the control group were fed a basal diet,and those in the experimental group were fed the basal diet supplemented with compound prebiotic composition(composed of Bacillus coagulans,dietary fiber from various sources and ω-3 and ω-6 unsaturated fatty acids at a ratio of 1∶3),which contained 2×10^(7) CFU Bacillus coagulans,1.15 g dietary fiber and 4 g unsaturated fatty acids per 100 g of diet.The pre-trial period was 2 weeks and the trial period was 6 weeks.The results showed as follows:1)compared with the control group,there were no significant differences in daily feed intake,fecal score,fecal pH and body weight of cats in the experimental group(P>0.05).2)Compared with the control group,there were no significant differences in nutrient apparent digestibility,blood routine indices and serum biochemical indices of cats in the experimental group(P>0.05).3)Compared with the control group,the serum immunoglobulin M(IgM)content and superoxide dismutase(SOD)activity of cats in the experimental group were significantly increased(P<0.05).4)Compared with the control group,the hair score of cats in the experimental group showed an increasing trend(P=0.078).5)Compared with the control group,there was no significant difference in intestinal microflora α diversity indices of cats in the experimental group(P>0.05),but the number of unique intestinal microflora was increased.Compared with the control group,at the phylum level,the Proteobacteria relative abundance in the experimental group was significantly increased(P<0.05);at the genus level,the Catenibacterium relative abundance in the experimental group showed an increasing trend
