摘要
随着生活水平的不断提高,消费者对牛肉数量及质量的需求日益增加。中国黄牛由于优越的食用品质深受消费者喜爱,但由于其产肉性能较低,影响了中国黄牛产业的发展。本文系统综述了影响中国黄牛育肥性能的主要因素,包括品种和地域、营养水平和饲喂方式,并对比了同品种不同时期的胴体性状变化,最后探讨了影响中国黄牛育肥性能的分子机理,旨在为中国黄牛遗传资源保护、高效养殖以及遗传选育方面提供理论依据。
With the continuous improvement of living standards,consumer demand for both the quantity and quality of beef has been steadily increasing.Chinese yellow cattle are highly favored by consumers due to their superior eating quality.However,their low meat production performance has hindered the development of the industry.This paper systematically reviews the main factors influencing the fattening performance of Chinese yellow cattle,including breed and region,nutritional levels and feeding methods.It further compares carcass trait changes within the same breed across different growth periods.Finally,the molecular mechanisms underlying fattening performance are explored.The aim is to provide a theoretical basis for the conservation of Chinese yellow cattle genetic resources,efficient breeding practices,and genetic selection programs.
