摘　　要：试验旨在探究石榴皮粉对雏鸭生长性能、屠宰性能、肠道发育和血清抗氧化指标的影响。选取320只7日龄淮南麻鸭,随机分为4组,每组8个重复,每个重复10只雏鸭。对照组饲喂基础饲粮,处理Ⅰ组、Ⅱ组、Ⅲ组分别在基础饲粮中添加0.5%、1.0%和2.0%的石榴皮粉。试验期28 d。结果显示,与对照组相比,处理Ⅲ组雏鸭的末重、平均日增重和半净膛率显著增加(P<0.05)。与对照组相比,处理Ⅲ组雏鸭十二指肠和空肠的器官指数、绒毛高度和绒隐比显著增加(P<0.05),隐窝深度显著降低(P<0.05);处理Ⅲ组雏鸭回肠的绒毛高度、绒隐比显著增加(P<0.05);处理Ⅱ组雏鸭空肠的器官指数、绒毛高度和绒隐比显著增加(P<0.05),隐窝深度显著降低(P<0.05)。与对照组相比,处理Ⅱ组和处理Ⅲ组雏鸭血清中总抗氧化能力(T-AOC)和谷胱甘肽过氧化物酶(GSH-Px)活性均显著增加(P<0.05),各处理组雏鸭血清中丙二醛(MDA)含量均显著降低(P<0.05)。研究表明,饲粮中添加石榴皮粉可有效改善雏鸭生长性能、屠宰性能和抗氧化能力,促进雏鸭肠道发育,最适添加量为2.0%。The study aimed to investigate the effects of pomegranate peel powder on the growth performance,slaughter performance,intestinal development,and serum antioxidant indexes of ducklings.A total of 320 seven-day-old Huainan mottled ducks were randomly divided into four groups,with eight replicates per group and 10 ducklings per replicate.The control group was fed a basic diet,while the Ⅰ,Ⅱ,and Ⅲ groups were supplemented with 0.5%,1.0%,and 2.0%pomegranate peel powder in the basic diet,respectively.The test period was 28 days.The results showed that compared to the control group,the final weight,average daily weight gain,and semi-eviscerated rate of ducklings in the treatment Ⅲgroup were significantly increased(P<0.05).Compared to the control group,the organ index,villus height,and villus/crypt ratio of the duodenum and jejunum in ducklings of the treatment Ⅲ group were significantly increased(P<0.05),while the crypt depth was significantly reduced(P<0.05).The villus height and villus/crypt ratio of the ileum in ducklings of the treatment Ⅲ group were significantly increased(P<0.05).The organ index,villus height,and villus/crypt ratio of the jejunum in ducklings of the treatment Ⅱ group were significantly increased(P<0.05),while the crypt depth was significantly reduced(P<0.05).Compared to the control group,the total antioxidant capacity(T-AOC) and glutathione peroxidase(GSH-Px) activity in the serum of ducklings in the treatment Ⅱ and Ⅲ groups were significantly increased (P<0.05),and the malondialdehyde(MDA) content in the serum of ducklings in all treatment groups was significantly reduced(P<0.05).The study indicates that the addition of pomegranate peel powder in the diet can effectively improve the growth performance,slaughter performance,and antioxidant capacity of ducklings,promote the intestinal development of ducklings,with the optimal addition level being 2.0%.
