Abstract This study was conducted to evaluate the effects of coated cysteamine (CCS) on growth performance, carcass characteristics, meat quality, and lipid metabolism in finishing pigs. A total of 160 pigs (62.12 ± 1.43 kg body weight) were randomly divided into 4 groups, with 4 pens per group and 10 pigs (5 gilts and 5 barrows) per pen. Pigs were fed a basal diet supplemented with 0, 100, 200, or 400 mg/kg CCS, corresponding to 0, 27, 54, or 108 mg/kg cysteamine, respectively. All pigs were given free access to feed and water for forty days. Average daily gain, average daily feed intake and feed to gain ratio were not affected by the CCS treatment. Supplemental CCS increased carcass lean ratio linearly (P

包衣半胱胺对育肥猪生长性能、胴体特性、肉质和脂质代谢的影响

摘要 本研究旨在评估包衣半胱胺 (CCS) 对育肥猪生长性能、胴体特性、肉质和脂质代谢的影响。160头猪（62.12±1.43kg体重）随机分为4组，每组4圈，每圈10头猪（5头小母猪和5头公猪）。给猪喂食补充有 0、100、200 或 400 mg/kg CCS（分别对应于 0、27、54 或 108 mg/kg 半胱胺）的基础日粮。所有猪在四十天内都可以自由进食和饮水。平均日增重、平均日采食量和料重比不受 CCS 处理的影响。补充 CCS 线性增加胴体瘦肉率 (P
