摘要
本试验就高步(CO)、爱拔益加(AA)、哈巴德(HU)、强基(CH)和农林501(NR)等五种肉用仔鸡的生产性能指标进行了对比测定。结果表明:在统计期内(0～9周龄)各品种都表现出了较高的生产水平。其中CO鸡的绝对增重最大(3393.22克),HU鸡的体重加倍次数最多(88.15倍),CH鸡的抗病力强,育成率最高(97.9％),而AA鸡的饲料转化率最高(2.24),NR鸡由于品种培育的程度较差,所以各项指标均低于其他品种。综合各项指标表明,所测定品种的优劣顺序由高到低为:CO鸡→CH鸡→AA鸡→HU鸡→NR鸡。
The production peformence targets of the five varieties of broiler GO(Gobb), AA( Arbor Acres), HU ( Hubbard ) , CH ( Chunky ) and NR ( Norin501 ) were determined in this trial, It shows that all the breed’s production levels are high during the test period ( 0-9 week ) The top absolute increase liveweight is Go’s ( 3393.22g) , the top ration of 9 week’s liveweght to birthweight is HU’s(88.15), CH has a most strong resisting power to disease and it’s survival rate is 97.9%, And AA’s Food C.rate is highest ( male 2.15, famale 2.24), NR is a developing breed and all the indxes are lower than other’s, Synthesizing all kinds of target, it shows that the breed’s quality grade (from high to low ) is as follows. GO→CH→AA→HU→NR
