| 摘要: |
| 将180只21日龄AA肉鸡分为6组，Ⅰ组饲喂豆油日粮，Ⅱ～Ⅵ组饲喂鱼油日粮;在Ⅱ～Ⅵ组鱼油日粮中，Ⅲ～Ⅴ组分别添加15，45，75 mg/kg β-胡萝卜素，Ⅵ组则添加200 mg/kg维生素E(VE)，研究β-胡萝卜素和VE对饲喂鱼油日粮鸡肉中脂肪酸组成、肉色、滴水损失、SOD活性和丙二醛含量影响。结果表明，与豆油日粮相比，在肉鸡日粮中添加鱼油，可增加鸡肉中饱和脂肪酸和ω-3多不饱和脂肪酸的相对含量，降低鸡肉的肉色；在鱼油日粮中添加不同水平的β-胡萝卜素和VE，可增加鸡肉的SOD活性，减少鸡肉的滴水损失和丙二醛含量。 |

| Abstract: |
| 180 3 week-old AA broilers were averaged in six treatments.Treatment Ⅰ was fed on soybean oil diet,treatment Ⅱ-Ⅵ was fed on fish oil diet，treatment Ⅲ，Ⅳ，Ⅴ and Ⅵ were formulated by supplementing 15,45,75 mg/kg β-carotene,200 mg/kg VE into the fish oil diet.The objective of this trail is to study the effect of the content of ω-3 fatty acid and the efficacy of VE or β-carotene on the composition of fatty acid,meat color,drip loss,activity of SOD enzyme and the content of MDA in chicken meat.The main results are:the supplementing fish oil into broilers diet can increase the content of ω-3 PUFA and SFA,and can decrease meat color in meat.When fish oil diet is supplemented with different levels of VE or β-carotene,activity of SOD enzyme can increase markedly,but meat drip loss and concentration of MDA can be reduced. |
