河北省肉牛遗传改良现状、存在的问题及发展建议OA

The beef cattle industry is an important pillar industry for the transformation and upgrading of the livestock industry in Hebei Province and for the increase of farmers'income and prosperity.The selection and breeding of superior breeds as well as the improvement of population genetics directly affect the development level of this industry.This study examined the development foundation of the beef cattle breeding industry in Hebei Province,including the breed types,composition of germplasm resources,and industrial layout.It also analyzed the current status and phased achievements of beef cattle genetic improvement in the province in terms of purebred breeding,technology application and promotion,and policy support.Based on this,the study summarized the main practices and practical experience formed in beef cattle genetic improvement through an analysis of four typical cases.The research indicated that there are still several constraints in the genetic improvement work of beef cattle in Hebei Province.First,the conservation of local breeds was still in the early stages.There were deficiencies in independent innovation capabilities,and modern biotechnology breeding techniques had not yet been widely applied.Second,although the breeding system had basically taken shape,its overall operational efficiency remains low,collaboration among stakeholders is insufficient,and the enthusiasm for genetic improvement at the grassroots level needs to be further enhanced.Third,breeding objectives are not yet closely aligned with market demand,and targeted breeding for high-end beef production and differentiated market demand still lags behind.In response to these problems,this study proposed countermeasures and suggestions in three aspects:strengthening germplasm resource protection and independent innovation capacity building;improving the breeding system and collaborative support mechanisms;and promoting industry integration and differentiated development oriented to market demand.The above suggestions provided a reference to the further advancement of beef cattle genetic improvement work in Hebei Province and the transformation and upgrading of the beef cattle industry.
