摘要: 鸭掌作为具有重要经济价值的家禽副产品,其消费需求迅速增加。尺寸越大、重量越重的鸭掌越受消费者喜爱,品质育种是获得该优良性状的手段之一。国内外学者开展了关于鸭掌形态、重量、尺寸、肉质等性状的研究,但与鸭掌品质育种的相关研究未见报道。全面理解鸭掌生长发育的调控机制,筛选与之相关的遗传标记,是开展鸭掌品质育种的重要理论基础,可为肉鸭品种改良工作提供重要的遗传资源。因此,作者就有关鸭掌各性状的研究进展进行综述,介绍了鸭掌的基本构造及鸭掌外观形态、重量、尺寸、肉质的测量指标和方法,简述了鸭掌在鸭胚胎时期的发育过程,重点讨论了影响鸭掌的尺寸、重量、外观形态和肉质的因素,从遗传角度分析了对鸭掌进行品质育种的可行性,整理了在前期研究中发现的与鸭掌有关的基因和遗传标记,分析了鸭掌肉品质研究的现代技术和应用前景。最后,对未来鸭掌的育种方向提出了展望,主张利用现代技术对鸭掌进行准确评估,并且通过筛选与跖骨和趾骨相关的分子遗传标记,培育出拥有尺寸更大、重量更重的鸭掌的肉鸭品系,不仅有更高的经济价值,还有利于鸭的健康,进一步提高生产性能,为肉鸭遗传改良和相关行业的发展奠定基础。

Abstract: Duck feet,as an important byproduct of poultry with significant economic value,have witnessed a rapid increase in consumer demand.Consumers prefer larger-sized and heavier duck feet,making quality breeding one of the means to obtain these desirable traits.While scholars both domestically and internationally have conducted research on the morphology,weight,size,and meat quality of duck feet,there is a lack of reported studies on quality breeding of duck feet.A comprehensive understanding of the regulatory mechanisms underlying the growth and development of duck feet,as well as the screening of associated genetic markers,serves as an important theoretical foundation for quality breeding.It can provide crucial genetic resources for the improvement of meat duck varieties.Therefore,this paper provides an overview of the research progress on various traits of duck feet,including their basic structure,external morphology,weight,size,and meat quality measurement indicators and methods.It briefly describes the developmental process of duck feet during the embryonic stage,and focuses on discussing factors influencing the size,weight,external morphology,and meat quality of duck feet.Feasibility of quality breeding of duck feet is analyzed from a genetic perspective,and genes and genetic markers related to duck feet discovered in previous studies are summarized.Moreover,modern technologies and prospects for the study of duck feet meat quality are analyzed.Finally,this paper presents prospects for the future breeding direction of duck feet,advocating for the accurate assessment of duck feet using modern techniques,and the cultivation of meat duck strains with larger size and greater weight through the selection of molecular genetic markers associated with metatarsal and toe bones.This approach not only enhances their economic value but also benefits the health of ducks,further improving production performance and laying the foundation for genetic improvement of meat ducks and the development of related industries.
