| 摘 要： | 本试验研究了α-硫辛酸在0、30、60、90mg/kg四个剂量下对肉仔鸡生产性能和胴体性能的影响。将240只1日龄科宝480肉仔鸡,随机分为4个处理组,每组6个重复,每个重复10只,试验期21d。结果表明：肉仔鸡30mg/kg和60mg/kg剂量组的料肉比显著降低2.03%~3.38%（P〈0.05）;90mg/kg剂量组的肉仔鸡日增重显著下降;肉仔鸡的腿肌率随着剂量的增加而显著提高2.24%~5.22%（P〈0.05）;胸肌率随着剂量的增加由提高变为降低;腹脂率、皮脂厚和肌间宽度随着剂量的增加显著降低（P〈0.05）。本试验结果表明,硫辛酸可以提高肉仔鸡的生产性能,改善肉品质,建议生产中使用30mg/kg和60mg/kg的添加量。

| Abstract: | An experiment was conducted to evaluate the effects of alpha-lipoic acid （LA） at graded levels （0,30,60,90mg/kg） on growth performance and carcass traits of broilers. A total of 240 1-day-old male Kebao dS0 broilers were randomly allocated to 4 dietary treatments, 10 broilers in each. Birds were slaughtered on 21 days old. Supplementation of LA in broiler diet at 30 mg/kg and 60 mg/kg gave significantly （P〈0.05） higher feed to gain ratio （F/G） than control by 2.03%-3.38%. LA at 90mg/kg had significantly （P〈0.05） decrease average daily gain than control. Accompanying dose increase, the leg muscle rates of broilers were significantly （P〈O.05） increased than control by 2.24%~5.22%, but the breast muscle rates were changed from increase to decrease with the rising dose. The abdominal fat rate, the thickness of subcutaneous fat and the width between muscle were significantly （P〈0.05） decreased as the dosage increased. It is concluded that alpha-lipoic acid can improve the growth performance and meat quality of broiler, and the suggest dosage would be 30 mg/kg to 60 mg/kg diet. |
