摘要/Abstract

摘要： 试验通过在日粮中添加不同水平的锰研究锰对4～6周龄肉仔鸡生产性能、胴体性能及肉品质的影响。480只1日龄Arbor Acres（AA）公雏饲养于60个笼中，每个笼中8只,0～3周龄统一饲喂同种日粮（含锰127.33 mg/kg）。于22日龄从中选取384只鸡按体重随机分成8个组，每组8个重复，每个重复6只鸡，分别饲喂不添加锰的玉米—豆粕型基础日粮(对照组，含锰13.69 mg/kg)和在基础日粮中分别添加20、40、60、80、100、120和140 mg/kg锰(试剂级硫酸锰)日粮。试验期21 d。结果表明，添加不同水平锰对4～6周龄肉仔鸡日采食量、日增重、料重比、全净膛率，胸肌率、腿肌率、胸肌滴水损失、剪切力、L*值、a*值和b*值、腿肌滴水损失、剪切力、L*值、a*值和b*值均无显著影响（P>0.10），但随着日粮锰水平的提高，肉仔鸡腿病发生率有降低趋势、胸肌和腿肌pH有提高趋势，且添加80 mg/kg锰时日增重最高、腹脂率最低。

关键词: One experiment was conducted to investigate the effects of different dietary manganese (Mn) levels on growth performance; carcass traits and meat quality of 4 to 6 weeks old broilers. A total of 480 1-day-old male Arbor Acres chickens were allotted to sixty cages with eight chickens each and fed the same diet (containing 127.33 mg/kg Mn) until 21 days of age. At 22 days of age; 384 birds were selected and randomly allotted by body weight to one of eight treatments (eight cage replicates of six chicks each) in a completely randomized design; and fed a Mn-unsupplenented corn-soybean meal basal diet (control; containing 13.6 mg/kg Mn) or the basal diet supplemented with 20; 100; 120 and 140 mg/kg Mn as Mn sulfate for a duration of 21 days. The results showed that there were no significant differences (P> 0.10) in ADG; ADFI; F/G; percentages of eviscerated yield; breast and leg muscles; drip loss; shear force; L* value; a* value and b* value of breast and leg muscle. However
