A study was conducted to evaluate the influence of chestnut tannins (CT) on welfare, carcass characteristics, meat quality, and lipid oxidation in rabbits under high ambient temperature. Rabbits in one group were raised at 20°C and fed with basal diet (N) and other three groups (33°C) were fed basal diet with 0 (C), 5 (CT5), and 10 g (CT10) of CT/kg of diet. Compared with the C group, rabbits in CT10 had higher pH(24) and lower cooking loss and thiobarbituric acid reacting substance values at 0, 30, and 60 min of forced oxidation. Rabbits in C group had higher cortisol levels, creatine kinase activities, white blood cell counts, neutrophil percentage, neutrophil:lymphocyte ratio and lower T(3), T(4) levels, lymphocyte percentage than N and CT10 groups. Supplementation of CT seemed to have a positive effect on growth performance, welfare, and meat quality of rabbits under high ambient temperature.
一项研究旨在评估在高温环境下，板栗单宁（CT）对兔子福利、胴体特性、肉质和脂质氧化的影响。一组兔子在 20°C 下饲养，并喂食基础日粮（N），而另外三组（33°C）则喂食基础日粮，其中 0（C）、5（CT5）和 10 g（CT10）/kg 日粮中添加 CT。与 C 组相比，CT10 组兔子在 0、30 和 60 分钟强制氧化时的 pH（24）更高，蒸煮损失和硫代巴比妥酸反应物值更低。C 组兔子的皮质醇水平、肌酸激酶活性、白细胞计数、中性粒细胞百分比、中性粒细胞与淋巴细胞比值较高，而 T（3）、T（4）水平、淋巴细胞百分比较低，与 N 和 CT10 组相比。在高温环境下，CT 的补充似乎对兔子的生长性能、福利和肉质有积极影响。
