摘要
文章旨在研究日粮添加金银花对肉兔生长性能,肠道抗氧化指标和肠道形态的影响.试验将 400 只 30 日龄断奶仔兔随机分为 4 组,每组 10 个重复,每个重复 10 只.试验日粮在基础日粮中添加 0%、0.05%、0.10%和 0.2%的金银花提取物.结果表明,日粮添加金银花对肉兔生长性能有显著影响,与对照组相比,日粮添加 0.1%金银花组的肉兔终末体重显著提高 5.4%(P＜0.05),平均日增重显著提高 6.8%(P＜0.05),料重比显著降低 7.2%(P＜0.05);此外,日粮添加金银花对肉兔平均日采食量无显著影响(P＞0.05).日粮添加 0.1%和 0.2%的金银花提取物可显著提高肉兔肠道T-SOD和T-AOC活性(P＜0.05);日粮添加金银花对肉兔肠道CAT、Cu-Zn SOD和GSH-Px活性无显著影响(P＞0.05).日粮添加 0.1%和 0.2%的金银花提取物可显著提高肉兔十二指肠绒毛高度和V/C值(P＜0.05),日粮添加 0.05%和 0.2%的金银花可显著提高肉兔回肠绒毛高度和V/C值(P＜0.05),此外,日粮添加金银花对肉兔十二指肠隐窝深度、空肠绒毛高度、隐窝深度及V/C值和回肠隐窝深度均无显著影响(P＞0.05).综上所述,在本试验条件下,肉兔日粮金银花最适添加量为 0.1%.
Abstract
The aim of this study is to investigate the effects of adding honeysuckle to the diet on the growth performance,intestinal antioxidant indicators,and intestinal morphology of meat rabbits.Select 400 weaned rabbits at the age of 30 days and randomly divide them into 4 groups,with 10 replicates in each group.Add 0%,0.05%,0.10%,and 0.2%honeysuckle extract to the basic diet as the experimental feed.The addition of honeysuckle to the diet had a significant impact on the growth performance of meat rabbits.Compared with the control group,the diet supplemented with 0.1%honeysuckle increased the final body weight of meat rabbits by 5.4%,increased the average daily weight gain by 6.8%,and decreased the feed to weight ratio by 7.2%(P＜0.05);In addition,the addition of honeysuckle to the diet had no significant effect on the average daily feed intake of meat rabbits(P＞0.05).Adding 0.1%and 0.2%honeysuckle extract to the diet significantly increased the intestinal T-SOD and T-AOC activities of meat rabbits(P＜0.05);Adding honeysuckle to the diet did not significantly affect the activities of CAT,Cu Zn SOD,and GSH Px in the intestines of meat rabbits(P＞0.05).Adding 0.1%and 0.2%honeysuckle extract to the diet significantly increased the duodenal villus height and V/C value of meat rabbits(P＜0.05),while adding 0.05%and 0.2%honeysuckle significantly increased the jejunal villus height and V/C value of meat rabbits(P＜0.05).In addition,adding honeysuckle to the diet had no significant effect on the depth of duodenal crypt,jejunal villus height,crypt depth,V/C value,and ileal crypt depth of meat rabbits(P＞0.05).In summary,under the conditions of this experiment,the optimal amount of honeysuckle added to the diet of meat rabbits is 0.1%.
