Protective effect of Stenotrophomonas acidaminiphila A2 on quail feeding on AFB1 contaminated diet
In order to study the protective effect of Stenotrophomonas acidaminiphila A2 derived from the gut of the black soldier fly larvae on Japanese quail feeding on AFB1,the quail diet with different concentrations of A2 bacterial agent(1 kg/t and 2 kg/t)were fed for 30 days,and the quail diet containing(95.34±2.62)μg/kg AFB1.The protective role of A2 against the hazards caused by AFB1 was evaluated by measuring the production performance,organ indices,serum biochemistry,antioxidant capacity of liver and kidney,egg quality,and the content of AFB1 in the liver and eggs.The results showed that the addition of A2 significantly reduced the negative impact of AFB1 on the feed-to-egg ratio,liver and spleen indices,and the elevation of serum alkaline phosphatase(ALP),glutamic pyruvic transaminase(ALT),triglyceride(TG),etc.in quail.The addition of A2 significantly increased the levels of total antioxidant capacity(T-AOC),superoxide dismutase(SOD),and glutathione peroxidase(GPx)in the liver and kidney tissues of quails affected by AFB1,and it ameliorated the negative impacts of AFB1 on eggshell weight,eggshell strength,and egg shape index.The A2 bacterial agent reduced AFB1 residues in liver and eggs.Furthermore,as the concentration of A2 increased,the improvement effects became more pronounced.In conclusion that A2 exhibited a certain protective effect against the negative impacts of AFB1 on quails.
