摘要
为研究饲粮中添加不同比例黄秋葵秸秆对肉兔生长性能、血液生化指标及盲肠菌群结构的影响,试验选用80只体重相近的断奶肉兔,公母各半,随机分为4组,每组5个重复,每个重复4只兔。对照组饲喂基础饲粮,试验组(4%组、6%组和8%组)分别饲喂含4%、6%、8%黄秋葵秸秆的饲粮,预试期7 d,正式期35 d。结果表明:(1)与对照组相比,饲粮中添加4%、6%、8%的黄秋葵秸秆均可以明显降低断奶肉兔的死亡率,改善断奶肉兔的腹泻情况,其中以4%组效果最好。(2)4%添加组总胆固醇显著低于对照组(P<0.05),其他试验组总胆固醇含量均有降低,但差异不显著(P>0.05);各试验组兔血液中的总胆红素、肌酐、尿素均有不同程度的降低,但差异均不显著(P>0.05);天门冬氨酸氨基转移酶、丙氨酸氨基转移酶均有一定程度的提高,差异不显著(P>0.05)。(3)在Alpha多样性上,Chao1指数,6%添加组显著低于对照组、4%组和8%组(P<0.05),Shannon指数和Simpson指数,各组之间差异均不显著(P>0.05);在门、属水平上,不同黄秋葵秸秆添加量对优势菌属和优势菌门均无显著性影响(P>0.05),但添加8%的黄秋葵秸秆可以提高厚壁菌门、拟杆菌门、瘤胃球菌属、颤螺旋菌属的相对丰度,降低变形菌门的相对丰度。由此可见,肉兔饲粮中添加4%的黄秋葵秸秆对肉兔肝肾功能有一定的调节作用,并可以显著降低肉兔生长过程中的死亡率,添加8%的黄秋葵秸秆可提高一些优势菌群的相对丰度,降低有害菌群的丰度。
The aim was to study the effects of adding different proportions of okra straw to the diet on the growth performance,blood biochemical indexes and cecum flora structure of rabbits.80 weaned rabbits of similar weight,half male and half female,were randomly divided into 4 groups of 5 replicates each,with 4 rabbits in each replicate.The control group was fed the basic diet,and the experimental groups(4%group,6%group and 8%group)were fed diets containing 4%,6%and 8%okra straw,respectively,the pre-test period lasted for 7 days,and the experimental period lasted for 30 days.The results showed that:(1)Compared with the control group,the addition of 4%,6%and 8%okra straw to the diet could significantly reduce the mortality rate of weaned rabbits and improve the diarrhea of weaned rabbits,with the 4%group having the best effect.(2)The total cholesterol of weaned rabbits with 4%added group was significantly lower than that of the control group(P<0.05),and the total cholesterol content in the other test groups was reduced,but the difference was not significant(P>0.05);Total bilirubin,creatinine and urea in the blood of rabbits in all test groups were reduced to different degrees,but none of the differences were significant(P>0.05);Aspartate aminotransferase and alanine aminotransferase were increased to some extent,and the differences were not significant(P>0.05).(3)On the alpha index,Chao1 index,6%added group was significantly lower than control group,4%group and 8%group(P<0.05),Shannon index and Simpson index,the differences among the 4 groups were not significant(P>0.05);At the level of phylum and genus,different additions of okra straw had no significant effect on the dominant genus and dominant phylum(P>0.05),but the addition of 8%of okra straw could increase the relative abundance of Firmicutes,Bacteroidetes,Ruminococcus and Oscillospira and reduce the relative abundance of Proteobacteria.It could be seen that the addition of 4%okra straw in the diet of rabbits had a certain regulatory effect on the liver and kidney f
