Abstract Rabbit meat is highly appreciated for its high nutritional and dietetic quality, which could be enhanced by natural additives. Therefore, in this study, the effect of bacteriocinogenic and probiotic strain Enterococcus faecium EF9a isolated from Pannon White rabbits was checked on growth and meat quality (pH, colour, water holding capacity (WHC) , protein, fat and energy content) of broiler rabbits in a model experiment. The average daily weight gain was higher in EF9a group (p < .0001). The treatment did not have a negative influence on the pH, colour, WHC, protein and fat contents or energy value of the rabbit carcase. Inferring from these results we conclude that the application of this new bacteriocinogenic E. faecium EF9a strain with probiotic properties could be promising in rabbit farms. HIGHLIGHTS The new bacteriocinogenic E. faecium EF9a strain could be used in rabbit farms. The EF9a strains application increased average daily weight gain. Treatment with the EF9a strain does not affect meat quality.

潘农白兔有益菌粪肠球菌EF9a对家兔生长性能和肉品质的影响

摘要 兔肉以其高营养和营养品质而备受推崇，天然添加剂可以增强这种品质。因此，在本研究中，检查了从 Pannon 白兔中分离的产细菌和益生菌菌株屎肠球菌 EF9a 对肉兔的生长和肉质（pH、颜色、持水能力（WHC）、蛋白质、脂肪和能量含量）的影响在模型实验中。EF9a 组的平均每日体重增加较高（p < .0001）。处理对兔尸体的 pH 值、颜色、WHC、蛋白质和脂肪含量或能量值没有负面影响。从这些结果推断，我们得出结论，这种具有益生菌特性的新型产细菌粪肠球菌 EF9a 菌株在兔场中的应用可能是有前途的。亮点 新的产细菌 E. feecium EF9a 菌株可用于养兔场。EF9a 菌株的应用增加了平均每日体重增加。用 EF9a 菌株处理不会影响肉质。
