摘要
本研究探讨了L-精氨酸（L-Arg）和L-肉碱（LC）单独或联合补充对50周龄公鸡的血液参数、脂质过氧化、睾丸组织结构、繁殖性能和激素水平的影响。32只阿里安品种（Arian breed）的肉鸡种鸡被随机分为四个实验组：1）对照组（CON）；2）日粮中添加150毫克/千克L-肉碱；3）日粮中添加500毫克/千克L-精氨酸；4）日粮中同时添加75毫克/千克L-肉碱和250毫克/千克L-精氨酸。睾丸组织分析显示，L-肉碱组中的丙二醛水平显著低于其他组（P < 0.05）。日粮中添加150毫克/千克L-肉碱后，生精小管直径、生精上皮厚度、小管间结缔组织体积以及精子生成指数均显著增加（P < 0.05）。摄入L-精氨酸和L-肉碱混合日粮的公鸡FSH和睾酮浓度也更高（P < 0.05）。L-肉碱组 impurity levels in the LC group were significantly reduced compared to the other treatment groups (P ?
