摘要

我国已连续多年成为世界第一猪肉生产大国和消费大国,但是我国猪肉品质的国际竞争力却不能与此相提并论。优良的猪肉品质所蕴含的经济价值毋庸置疑,而且生产优质猪肉也是养猪业的终极目标,因此提高猪肉生产的科技水平、改善猪肉品质,是增强我国养猪业科技含量,保证我国养猪业可持续发展的重要环节。优良的猪肉品质是建立在健康、安全、生态和注重动物福利的养猪基础上的高端畜产品的特性,畜牧科技工作者对它的追求和研究,已经从最初的劣质猪肉的发生或成因深入到了如何改善猪肉肉色、风味、嫩度、多汁性和系水力等富有人文色彩的猪肉品质方面。本文从影响猪肉品质的肌肉生物学特性的2个方面,即肌纤维发育和肌内脂肪沉积,探讨了优质猪肉形成的分子机制和营养调节,综述和回顾了近年国际上该领域的最新进展和发展方向,提出了我国学者应在继承前人研究成果的同时,挖掘我国地方猪优质基因资源,利用营养基因组学和整合生理学的概念,促进我国优质猪肉研究、生产和发展的建议。

Abstract

China has become the largest pork production country in the world for a few years in succession. However, Chinese pork international competitiveness hardly matches its status of pork production. Considering good pork quality embraces a great deal of market value and high quality pork is the ultimate aim for pig industry, it is essential that advancing technologies of improving the pork quality to guarantee the sustainable development of the pig industry in China. High quality pork should be produced by a healthy, safe and ecological pig industry. Originally, a study on pork quality focused on identification of the genetic and environmental causes which lead to low quality pork. Now, it has extended how to improve pork qualities, including fresh meat color, favor, tenderness, water hold capacity, and animal welfare. In this paper, we discussed advancing in molecular mechanism and nutrient metabolism underlying high quality pork formation through two major aspects of muscle biological characteristics, i.e. myofiber development and intramuscular fat deposition. Furthermore, we also reviewed the progress of nutritional regulation of pork quality, and proposed that genetic resources of Chinese indigenous pig breeds should be put more attention on based on predecessors’ achievements, and the approaches of nutrigenomics and integrative physiology should be applied to accelerate the setting up of strategies of high quality pork production in China.
