艾维茵肉鸡是美国艾维茵国际家禽育种有限公司育成的白羽肉鸡。祖代种鸡采用四系配套制种方式,父本 A、B两系体重大,体躯宽而深,胸腿部肌肉发达,属于白科尼什肉鸡体型;母本C、D两系体型中等呈椭圆形,体躯紧凑、丰满,羽毛较紧密。 我国从1987年开始引进,目前在全国大部分省(自治区、直辖市)建有祖代和父母代种鸡场,是白羽肉鸡中饲养较多的品种。艾维茵肉鸡为显性白羽肉鸡,体型饱满,胸宽、腿短、黄皮肤,具有增重快、成活率高、饲料报酬高的优良特点。
The results showed that:The complex amino acid trace element chelated added with 0. 5 times NRC level improve the production performance of broiler prominently.
试验结果表明:0.5倍NRC水平的复合氨基酸螯合微量元素显著改善艾维茵肉鸡生产性能,生长速度比高铜水平复合氨基酸螯合微量元素提高4.72%(P<0.01),饲料采食量提高8.98%(P<0.01);肉鸡腿病发生率比硫酸盐组降低1.0倍,死亡率降低2.0倍。
