鸡抗病育种研究策略

Research Strategy on Breeding for Disease Resistance in Chickens

禽病控制一直是养禽业的难题,在现代养禽业生产中,除了加强饲养管理水平和应用药物、疫苗等措施来控制疾病外,提高鸡的自身抗病能力、进行抗病品系的筛选和培育越来越显示出其优势,利用基因工程进行抗病育种已成为研究热点。抗病力是由多因素控制的现状,筛选抗病力相关基因是抗病育种的关键内容。目前发现的与鸡抗病力相关的基因并不多,论文对抗病力相关的基因进行了阐述,并对抗病育种途径进行了简要介绍,提出转基因工程抗病育种必将成为家禽育种工作者的工具。

The control of poultry disease has been the problems in poultry industry.In addition to raising the management level and applocation of drugs and vaccines to control diseases,improving the chicken＇s own resistance to diseases and the screening and cultivation of disease resistant chickens have increasngly shown its unique advantages in the production of the mordern poultry industry.Breeding for disease resistance by genetic engineering has become a hot research.Resistance to disease is controlled by many facotrs and screening for disease resistance genes is a key element in disease resistance breeding.The author gave a brief introduction of disease resistance genes in chickens and proposed that trangenic engineering of breeding for disease resistance may become a powerful tools in the future.Finally the author prospected the foreground of breeding for disease resistance in chickens.
