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