驴种质资源现状、保护与利用OA

As a vital component of China's characteristic livestock genetic resources,the donkey was also once one of the country's major draft animals,with important economic value in a number of areas,including meat,skin,and dairy products.In recent years,China's donkey population has been declining at a rate of around 300,000 a year,with several local breeds facing the risk of endangerment.This study systematically reviews the current status and multifaceted values of donkey resources in China and conducts an in-depth analysis of the primary challenges facing the donkey industry,including inadequate protection of germplasm resources,low breeding efficiency,and lagging product development.Based on this analysis,we discuss scientific and effective strategies for the conservation and utilization of donkey germplasm resources.Proposed strategies include establishing specialized breeding farms,implementing comprehensive breeding programs,and leveraging genomic and other modern biotechnologies to enhance germplasm conservation.Additionally,the study suggests optimising large-scale breeding practices,enhancing the integration capacity of the industrial chain,and developing high value-added products to promote the sustainable development of the donkey industry.This paper aims to provide theoretical and practical guidance for the protection and efficient utilization of donkey germplasm resources and to support the transformation and upgrading of China's donkey industry.
