摘　　要：文章旨在探究不同水平益生菌对犬生长性能、养分表观消化率和免疫指标的影响。试验将健康状况良好、体重相近的4月龄比格犬随机分为4组,每组6个重复(雌雄对半),每个重复1只。试验日粮分别在基础日粮中添加0、0.05、0.1%和0.2%的复合益生菌,试验为期64?d。试验结果表明,在所有犬只初始体重一致的前提下(P> 0.05),日粮添加0.2%的复合益生菌可显著降低比格犬4.5%的料重比(P <0.05);日粮添加不同益生菌水平对比格犬终末体重、平均日增重、平均日增重均无显著影响(P> 0.05)。日粮添加0.2%的复合益生菌可显著提高比格犬的干物质和粗脂肪表观消化率(P <0.05);日粮添加0.1%和0.2%的复合益生菌可显著提高比格犬的粗蛋白表观消化率(P <0.05);日粮添加0.1%的复合益生菌显著提高比格犬的能量消化率(P <0.05);此外,日粮添加不同益生菌水平对比格犬淀粉表观消化率无显著影响(P> 0.05)。日粮添加0.2%的复合益生菌可显著降低比格犬血清IL-6含量(P <0.05);日粮添加0.1%和0.2%的复合益生菌可显著降低比格犬血清IL-10含量(P <0.05);日粮添加0.05%~0.2%复合益生菌显著降低比格犬血清TNF-α含量(P <0.05)。此外,日粮添加复合益生菌对比格犬血清IgA、IgM、IgG以及IL-1β含量均无显著影响(P> 0.05)。总之,在本试验条件下,比格犬日粮中复合益生菌最适添加量为0.2%。The aim of this experiment is to investigate the effects of different levels of probiotics on dog growth performance,nutrient apparent digestibility,and immune indicators.Four month old beagles with good health and similar weight were randomly divided into four groups,with six replicates(male and female in half)in each group,with one replicate per group.Add 0,0.05%,0.1%,and 0.2%of composite probiotics to the basic diet as the experimental feed for a total of 64 days.The experimental results showed that,under the premise of consistent initial body weight of all dogs(P>0.05),adding 0.2%compound probiotics to the diet significantly reduced the feed to weight ratio of beagles by 4.5%(P<0.05);The addition of different levels of probiotics to the diet had no significant effect on the final body weight,average daily gain,or average daily gain of beagles(P>0.05).Adding 0.2%compound probiotics to the diet significantly improved the apparent digestibility of dry matter and crude fat in beagles(P<0.05);The addition of 0.1%and 0.2%probiotics significantly increased the apparent digestibility of crude protein in beagles(P<0.05);Adding 0.1%compound probiotics to the diet significantly improved the energy digestibility of beagles(P<0.05);In addition,the addition of different levels of probiotics to the diet had no significant effect on the apparent starch digestibility of beagles(P>0.05).Adding 0.2%compound probiotics to the diet significantly reduced the serum IL-6 content of beagles(P<0.05);The addition of 0.1%and 0.2%probiotics to the diet significantly reduced the serum IL-10 content of beagles(P<0.05);Adding 0.05%~0.2%composite probiotics to the diet significantly reduces serum TNF in beagles-αContent(P<0.05)In addition,the addition of composite probiotics to the diet had an effect on serum IgA,IgM,IgG,and IL-1 levels in beaglesβThe content had no significant impact(P>0.05).In summary,under the conditions of this experiment,the optimal amount of compound probiotics added to the diet of beagles is 0.2%.
