The Effects of Dried Pomegranate Peel Powder on Preventing Chicken Coccidiosis
To investigate the preventive effect of dried pomegranate peel powder on chicken coccidiosis,this study used Ross 308 chicks as the research object.7-day-old chicks were divided into 5 groups:low-dose group(1.1 g/kg),high-dose group(3.1 g/kg),salinomycin group(650 mg/kg),negative control group and positive control group.Each group consisted of 5 replicates,with 10 chickens per replicate.Dur-ing 7 to 22 days of age,a coccidia-infection feeding experiment was conducted to evaluate its effect on pro-duction performance,anti-coccidiosis effect,serum biochemical indicators,serum antioxidant indices,and intestinal morphological structure following coccidia infection.The results indicated that prior to coccidia infection,the addition of 1.1 g/kg and 3.1 g/kg dried pomegranate peel powder to the basal diet signifi-cantly increased the body weight of infected chicks,reduced the feed-to-weight ratio,and improved growth performance.The highest ACI in the salinomycin group was 173.58,while the ACI for the low and high dose groups were 167.98 and 163.7,respectively,both achieving a moderate anti-coccidia effects.The addi-tion of different doses of dried pomegranate peel powder to the diet resulted in higher levels of GSH-PX and SOD compared to the positive control group,with a significant increase in T-AOC content in the low dose group(P＜0.01),and the serum MDA content was reduced in all treatment groups.Except for the high dose group,which exhibited lower VH in the jejunum compared to the positive control group,the VH and VH/CD ratios in the duodenum,jejunum,and ileum for the other groups were higher than those in the positive group.Thus,the addition of 1.1 g/kg dried pomegranate peel powder to the basial diet of chicks can enhance their growth performance,alleviate the bloody stool,oocyst count,and intestinal path-ological damage associated with coccidia infection,thereby improving overall health and immune function.The findings suggest that dried pomegranate peel powder has considerable preventive and therapeutic effects against chicken coccidiosis.
