中文摘要:本研究旨在探讨牛磺酸对肉仔鸡屠宰性能和肌肉品质的影响。选用240只1日龄艾维茵肉仔鸡,随机分为5组,每组3个重复。对照组饲喂玉米-豆粕型基础日粮,试验组在基础日粮中添加0.05%、0.10%、0.15%和0.20%的牛磺酸,试验期42 d。结果表明:(1)日粮中添加0.10%牛磺酸能够显著降低42日龄肉仔鸡胸肌失水率和粗脂肪含量(P<0.05),显著提高胸肌pH和粗蛋白质含量(P<0.05);(2)添加0.15%的牛磺酸显著提高42日龄肉仔鸡胸肌率和瘦肉率(P<0.05),显著降低皮脂厚(P<0.05),显著提高胸肌pH和粗蛋白质含量(P<0.05),显著降低胸肌粗脂肪含量(P<0.05);(3)0.20%的牛磺酸显著提高胸肌pH、肉色和粗蛋白质含量(P<0.05)。

外文摘要:The study was conducted to evaluate the effects of taurine on slaughter performance and meat quality of broilers.Two hundred and forty 1-day-old chicks were randomly divided into 5 groups, each group had 3 replicates , and fed basal diets with 0 % (control group), 0.05 %, 0.10 %, 0.15 % and 0.20 % taurine.The results showed that:( 1 )dietary taurine of 0.10 % remarkably decreased the breast muscle water loss rate and crude fat (P 〈 0.05) ,increased the breast muscle pH and crude protein on 42 day (P 〈 0.05) ; (2)0.15 % taurine significantly increased the rate of breast muscle and lean meat (P 〈 0.05),decreased the depth of skin fat (P 〈 0.05),increased the breast muscle pH and crude protein (P 〈 0.05) ,decreased the breast muscle crude fat (P 〈 0.05) ; (3)0.20 % taurine remarkably increased the breast muscle pH,muscle color and crude protein(P 〈 0.05).
