| 摘 要： | 研究日粮锌水平对4~6周龄肉仔鸡生长性能、胴体性能和肉品质的影响。360只1日龄Arbor Acres(AA)肉公雏,0~3周龄统一饲喂同种日粮(含锌86.25 mg/kg),于22日龄从中选取288只鸡按体重随机分成8个处理,每个处理分6个重复笼饲养,每个重复笼6只鸡。分别饲喂不添加锌的玉米-豆粕型基础日粮(对照组,含锌27.66 mg/kg)和在基础日粮中分别添加20、40、60、80、100、120和140 mg/kg锌(试剂级硫酸锌)日粮。试验期21 d。研究结果表明,日粮锌水平对4~6周龄肉仔鸡生长和胴体性能均无显著影响(P>0.10),但日粮中添加适宜水平的锌可显著降低肉仔鸡胸肌、腿肌的滴水损失和胸肌丙二醛含量,提高胸肌L*值(P<0.10)。

| Abstract: | An experiment was conducted to investigate dietary zinc level on growth performance,carcass traits and meat quality in broilers from 4 to 6 weeks of age.A total of 360 1-day-old male Arbor Acres chickens were fed the same diet(containing 86.25 mg/ kg Zn) until 21 days of age.At 22 days of age,288 chickens were randomly assigned to eight dietary treatments with six replicates by body weight and six chickens with each pen,and fed a Zn-unsupplenented corn-soybean meal basal diet(control,containing 27.66 mg/kg ... |
