一株米醋源植物乳杆菌发酵液对伊拉商品兔生产性能及肉品质的影响

Effects of a rice vinegar plant lactobacillus fermented liquid on the production performance and meat quality of Ira Rabbits

文章旨在研究饮水中添加植物乳杆菌发酵液MC090对伊拉商品兔生长性能、屠宰性能和肉品质的影响。试验选取同批次且健康度良好的32日龄兔216只,随机分为2组(对照组和试验组),每组3个重复,每个重复36只。试验组饮水中添加植物乳杆菌MC090发酵液5mL/L,分早中晚3次添加;对照组饮用自来水;试验为期23d。结果表明,(1)与对照组相比,试验组平均日增重有所增加,料肉比、死淘率均有所下降,但差异不显著(P>0.05);(2)与对照组相比,试验组空肠绒毛高度和V/C显著提高(P<0.05);(3)与对照组相比,试验组盲肠食糜pH,食糜总菌数和大肠杆菌数差异均不显著(P>0.05),乳酸杆菌数差异显著(P<0.05);(4)与对照组相比,试验组全净膛重、全净膛率、半净膛重、半净膛率,肌肉pH_(45min)、pH_(24h)、滴水损失率、L^(*)值、a^(*)值均无显著差异(P>0.05),剪切力和b^(*)值差异均显著(P<0.05)。综上所述,植物乳杆菌MC090发酵液可提升伊拉兔小肠绒毛高度,改善肠道健康度,促进兔生长,降低死淘率,降低料重比,提升生产效益。

The purpose of this experiment is to investigate the effect of adding Lactobacillus plantarum fermentation broth MC090 to drinking water on the growth performance,slaughter performance,and meat quality of Ira rabbits.Select 216 meat rabbits from the same batch with 32 day old and good health,and randomly divide them into two groups,namely the control group and the experimental group.Each group has 36 replicates,with 3 rabbits in each replicate.5ml/L of Lactobacillus plantarum MC090 fermentation broth was added to the drinking water of the experimental group,and added for drinking three times in the morning,middle,and evening;The control group drank ordinary tap water;The experimental period is 23 days.The results showed that:(1)The average daily weight gain of the experimental group increased,while the feed to meat ratio and mortality rate decreased,however,the differences in which were not significant(P > 0.05)compared with the control group;(2)The experimental group showed a significant increase in jejunal villus height and villus to crypt ratio(P < 0.05)compared with the control group;(3)There was no significant difference in pH,total bacterial count,and number of Escherichia coli in the cecal chyme of the experimental group(P > 0.05),while there was a significant difference in the number of lactobacilli(P < 0.05)compared with the control group;(4)The experimental group showed no significant differences in full bore weight,full bore rate,half bore weight,half bore rate,muscle pH45min,pH24h,drip loss rate,L* value,and a* value(P > 0.05),while there were significant differences in shear force and b* value(P < 0.05)compared with the control group.In summary,it can be seen that the fermented liquid of Lactobacillus plantarum MC090 can increase the height of small intestinal villi,improve intestinal health,Ira rabbits growth,reduce the mortality rate,reduce the material to weight ratio,and improve production efficiency.
