Effects of Zanthoxylum bungeanum Seed Meal Replacing Soybean Meal on the Growth Performance,Slaughter Performance,Serum Biochemical Indicators,Antioxidant Capacity,and Immune Function of Broilers
[Objective]This study was aimed to investigate the effects of substituting soybean meal with Zanthoxylum bungeanum seed meal on the growth performance,slaughter performance,serum biochemical indicators,antioxidant capacity,and immune function of broilers,so as to provide a potential strategy to reduce the reliance of soybean meal in broilers.[Method]A total of 180 AA broilers at 1 day of age,with a uniform body weight of 48.87 g±0.15 g,were selected and randomly assigned to 3 treatment groups,each consisting of 6 replicates with 10 chickens per replicate.The broilers in control group(CON)were fed a basic diet,while the experimental group received diets containing 2.5％(ZBM-1)and 7.5％(ZBM-2)Zanthoxylum bungeanum seed meal as a substitute for soybean meal in basic diet.The experimental period lasted for 42 d.The effects of replacing soybean meal with Zanthoxylum bungeanum seed meal on the growth performance,slaughter performance,serum biochemical indicators,antioxidant capacity,and immune function of broilers were analyzed.[Result]①Compared with CON group,the average daily weight gain,average daily feed intake,and feed to gain ratio of broilers in ZBM-2 group were significantly increased at 1-21,22-42,and 1-42 days of age(P＜0.05).② The eviscerated carcass weight rate of broilers in ZBM-2 group was significantly higher than CON and ZBM-1 groups(P＜0.05).③ Compared with CON group,the drip loss and cooking loss of muscle of broilers in ZBM-1 and ZBM-2 groups were significantly decreased(P＜0.05).④ Compared with CON group,the albumin and globulin levels in serum of broilers at 21 days of age in ZBM-2 group were significantly increased(P＜0.05),but the alanine aminotransferase activity was significantly decreased(P＜0.05).The albumin and globulin levels,and the alkaline phosphatase activity in serum of broilers at 42 days of age in ZBM-2 group were significantly increased(P＜0.05),but the total cholesterol content was significantly decreased(P＜0.05).⑤ Compared with CON group,the total antioxidant capacity,immunoglobulin A and immunoglobulin M levels,and the activities of superoxide dismutase and glutathione peroxidase in serum of broilers at 21 and 42 days of age in ZBM-2 group were significantly increased(P＜0.05),but the malondialdehyde content was significantly decreased(P＜0.05).[Conclusion]Under the conditions of this experiment,substituting Zanthoxylum bungeanum seed meal for soybean meal in diet could enhance the meat quality,antioxidant capacity,and immune function of broilers.The recommended usage rate of Zanthoxylum bungeanum seed meal in broilers was 2.5％.
