Effects of Lactobacillus Probiotics on Growth Performance,Nutrient Digestibility and Serum Biochemical Indexes in Arctic Foxes
摘要
Abstract
This experiment was conducted to study the effects of Lactobacillus probiotics on growth performance,nutrient digestibility and serum biochemical indexes in arctic foxes during the winter fur-growing period.Forty 135-day-old female arctic foxes with a similar body weight were randomly divided into 4 groups with 10 replicates per group and 1 fox per replicate.The fo-xes in control group were fed basal diets,while that of groups Ⅱ,Ⅲ and Ⅳ were fed basal diet+0.02% colistin sulfate,basal diet+1 mL Lactobacillus probiotics (active Lactobacillus was 3 × 10 9 CFU/mL)and basal diet+10 mL Lactobacillus probiotics,respectively.The results showed that:Compared to the control group,the addition of Lactobacillus probiotics significantly in-creased the average daily gain (P <0.05)and significantly decreased the F/G of arctic foxes dur-ing the winter fur-growing period (P <0.05).The apparent digestibility of EE and GE were sig-nificantly increased when arctic foxes fed diet supplemented with Lactobacillus probiotics (P <0.05).Supplementation of high level Lactobacillus probiotics could significantly decrease serum total cholesterol (P <0.05).Additionally,serum alanine aminotransferase concentration of group Ⅱ was extremely significantly higher than that of the other three treatments (P <0.01).Moreo-ver,the serum aspartate aminotransferase concentration was significantly higher than the control group (P <0.05).In conclusion,the addition of Lactobacillus probiotics had beneficial effects on growth performance and apparent digestibility of EE and GE when arctic foxes got 3 × 10 9 CFU/mL active Lactobacillus from the probiotics per day.The total cholesterol in serum was sig-nificantly decreased when arctic foxes get 3×10 10 CFU/mL active Lactobacillus from the probiot-ics per day.It might cause the liver damage when arctic fox got colistin sulfate for a long time.关键词
