摘要

本试验旨在研究饲粮中添加复合芽孢杆菌对宠物猫生长、养分表观消化率、血常规及血清生化指标和抗氧化功能的影响。试验选取20只体重相近的1~2岁成年布偶猫,随机分为对照组(饲喂基础饲粮)和试验组(饲喂含有3×109 CFU/kg益生芽孢杆菌的试验饲粮),每组10个重复,每个重复1只猫,试验期共33 d。结果表明:与对照组相比,1)试验组宠物猫的采食量和体增重均提高(P>0.05),软便率和腹泻率均降低(P>0.05);2)试验组干物质和粗蛋白质表观消化率以及消化能显著提高(P<0.05);3)试验组宠物猫血液中单核细胞数目及血清总蛋白、白蛋白以及葡萄糖含量显著降低(P<0.05),其他血液指标差异不显著(P>0.05);4)试验组血清中总抗氧化能力(T-AOC)和谷胱甘肽过氧化物酶(GSH-Px)活性显著提高(P<0.05),总超氧化物歧化酶(T-SOD)活性有所提高,但丙二醛(MDA)含量和过氧化氢酶(CAT)活性无显著变化(P>0.05)。综上所述,饲粮中添加益生芽孢杆菌可提高宠物猫养分表观消化率和机体抗氧化功能,从而改善宠物猫机体健康并降低腹泻率。

Abstract

The aim of this experiment is to investigate the effects of compound Bacillus on the growth, apparent digestibility of nutrients, the blood routine indicators, serum biochemical indices and the antioxidant capacity of pet cats. In the experiment, 20 adult puppet cats with similar body weights and 1 to 2 years of age were randomly divided into a control group (fed a basal diet) and an experimental group (fed the experimental diet containing 3×109 CFU/kg probiotic Bacillus). There were 10 replicates per group and 1 cat per replicate. The experiment lasted for 33 days. The results showed that compared with the control group, 1) the feed intake and body weight gain of the pet cats in the experimental group were increased (P>0.05), and the rates of soft stool and diarrhea were decreased (P>0.05); 2) the digestibilities of dry matter and crude protein and digestive energy in the experimental group were significantly improved (P<0.05); 3) the number of monocytes in the blood of the pet cats in the experimental group and the serum total protein, albumin and glucose contents were significantly reduced (P<0.05), and there were no significant differences for the other blood indexes (P>0.05); 4) the serum total antioxidant capacity (T-AOC) and glutathione peroxidase (GSH-Px) activity in the experimental group were significantly increased (P<0.05), and the total superoxide dismutase (T-SOD) was increased (P>0.05). However, the serum content of malondialdehyde (MDA) and the activity of catalase (CAT) did not change significantly (P>0.05). In summary, the addition of compound Bacillus in diet can increase the apparent digestibility of nutrients and the antioxidant capacity of pet cats, thereby promoting the body weight and reducing the diarrhea rate of pet cats.
