中国黄牛保种、选育及产业化利用现状与发展建议OA

Chinese yellow cattle are important livestock genetic resources in China and provide a fundamental germplasm basis for the development of the characteristic beef cattle industry and independent breeding innovation.This review systematically summarized the current status of germplasm resources of Chinese yellow cattle,as well as the recent progress in conservation,utilization,genetic improvement,and industrial development.The review focused on the research advances and practical constraints in within-breed breeding,crossbreeding improvement,and molecular breeding application,and analyzed the main problems and development needs in the utilization of these resources.The results showed that the conservation system for Chinese yellow cattle resources has been continuously improved in recent years,and related work on conservation,utilization,and breeding has progressed steadily.The development of Chinese yellow cattle has gradually shifted from resource conservation alone to equal emphasis on conservation and utilization.However,several problems still restrict their high-quality development,including the reduction of purebred resources,insufficient beef production performance,the failure of high-quality products to obtain premium market value,incomplete breeding planning and multiplication systems,a weak foundation for the application of modern breeding technologies,and a relatively low level of industrial utilization.At present,the resource advantages of Chinese yellow cattle have not been fully transformed into breeding and industrial advantages.Therefore,future efforts should strengthen systematic conservation of germplasm resources,improve within-breed breeding and crossbreeding systems,accelerate the application of molecular breeding technologies,and promote the coordinated development of conservation,breeding,and industrial utilization,to support the high-quality development of Chinese yellow cattle.
