Effects of astragalus membranaceus on growth performance,antioxidant indicators,immune indicators,and gut microbiota in young cats
To explore the effects of Astragalus membranaceus on growth performance,antioxidant indicators,immune indicators,and gut microbiota in young cats.This experiment used a random number table method to divide 48 Chinese pastoral kittens weaned around 50 days old into 4 groups,with 12 cats in each group.Each group had 4 replicates,with 3 cats in each replicate.The control group,experimental group I,experimental group II,and experimental group III were supplemented with 0%,0.2%,0.4%,and 0.6%Astragalus membranaceus in the basic diet,respectively.The formal experimental period was 30 days.The results showed that compared with the control group,the final weight and average daily gain of kittens in Experiment I,Experiment II,and Experiment III groups were significantly increased(P＜0.05);The feed to weight ratio of kittens in Experiment I,Experiment II,and Experiment III groups significantly decreased(P＜0.05);The levels of SOD,T-AOC,GSH-Px,IgG,IgM,and IgA in the venous serum of young cats in Experiment I,Experiment II,and Experiment III groups were significantly increased(P＜0.05);The content of MDA in the venous serum of young cats in Experiment I,Experiment II,and Experiment III groups significantly decreased(P＜0.05);The number of Escherichia coli,Staphylococcus aureus,and Salmonella in the fresh feces of kittens in Experiment I,Experiment II,and Experiment III groups significantly decreased(P＜0.05);The number of bifidobacteria and lactobacilli in the fresh feces of kittens in Experiment I,Experiment II,and Experiment III groups significantly increased(P＜0.05).The above results indicate that adding Astragalus membranaceus to the basic diet can improve the growth performance,antioxidant indicators,immune indicators,and intestinal microbiota of young cats,with the optimal dosage of Astragalus membranaceus being 0.6%.
