饲粮中添加葡萄籽提取物对产蛋高峰后期蛋鸡生产性能、血清抗氧化和抗炎能力的影响

Effects of Grape Seed Extract Supplementation on Production Performance,Serum Antioxidant and Anti-Inflammatory Capacity of Laying Hens in The Late Peak Stage of Egg Laying

试验旨在研究葡萄籽提取物对产蛋高峰后期蛋鸡生产性能、血清抗氧化和抗炎能力的影响。选取体况和产蛋性能相近的53周龄京粉2号蛋鸡540羽,并随机分成3组,分别为对照组(CON组)、葡萄籽提取物200 mg/kg组(G2组)、葡萄籽提取物300 mg/kg组(G3组),每组6个重复,每个重复30羽。CON组饲喂基础饲粮,G2组饲喂基础饲粮+200 mg/kg葡萄籽提取物,G3组饲喂基础饲粮+300 mg/kg葡萄籽提取物。试验期为60 d。结果显示:①与CON组相比,G3组的产蛋率、平均蛋重和平均日采食量显著提高,料蛋比显著降低(P<0.05)。②与CON组相比,G3组血清SOD活性显著提高,MDA含量显著降低(P<0.05)。③与CON组相比,G2组和G3组血清中IL-1β、IL-2、IL-4、IL-6、IL-10、TNF-α含量均有下降,但差异不显著(P>0.05)。综上所述,产蛋高峰后期蛋鸡饲粮中添加200、300 mg/kg葡萄籽提取物,对生产性能、血清抗氧化和抗炎能力的改善有着积极作用,且300 mg/kg添加水平效果最佳。

This experiment aims to study the effects of grape seed extract on the production performance,serum antioxidant and anti-inflammatory capabilities of laying hens during the late peak period of egg production.Five hundred and fourty 53-week-old Jingfen No.2 laying hens with similar body condition and egg-laying performance were selected and randomly divided into 3 treatment groups,namely the control group(CON group)and the grape seed extract 200 mg/kg group(G2 group),grape seed extract 300 mg/kg group(G3 group),each group has 6 replicates,each replicate has 30 pigeons.The CON group was fed basal diet,the G2 group was fed basal diet+200 mg/kg grape seed extract,and the G3 group was fed basal diet+300 mg/kg grape seed extract.The test period is 60 days.The results showed:①compared with the CON group,the egg production rate,average egg weight and average daily feed intake of the G3 group were significantly increased,and the feed-to-egg ratio was significantly decreased(P<0.05).②Compared with the CON group,the serum SOD activity of the G3 group was significantly increased and the MDA content was significantly decreased(P<0.05).③Compared with the CON group,the serum levels of IL-1β,IL-2,IL-4,IL-6,IL-10,and TNF-αin the G2 group and the G3 group all showed a downward trend,but the difference was not significant(P>0.05).In summary,adding 200 mg/kg grape seed extract and 300 mg/kg grape seed extract to the diet of laying hens during the late peak period of egg production has a positive effect on improving production performance,serum antioxidant and anti-inflammatory capabilities,and 300 mg/kg addition level has the best effect.
