摘要
反刍动物脂肪中的肌内脂肪含量对动物的肉品质有着重要的影响,可以通过营养均衡的饲养管理调节肌内脂肪的含量,从而有效的改善动物的肉品质。脂肪酸决定了动物体中脂肪的特性,探究脂肪酸的形成过程对脂肪沉积的研究具有重要意义。脂肪沉积受动物的品种、性别、年龄、饲养模式、环境、营养等各种因素的影响,通过改变牦牛肌内脂肪沉积进而改善牦牛肉的品质和口感。牦牛是青藏高原及毗邻地区特有畜种,是当地牧民生产和生活资料的主要来源。文章对影响牦牛脂肪沉积的因素进行了综述,为后续对牦牛脂肪沉积和牦牛肉品质的相关研究提供依据。
The intramuscular fat content in ruminant fat has an important impact on meat quality of animals.The intramuscular fat content can be adjusted through balanced nutrition feeding and management,so as to effectively improve the meat quality of animals.Fatty acids determine the characteristics of fat in animal body,so exploring the formation process of fatty acids is of great significance for the study of fat deposition.Fat deposition is affected by animal breed,sex,age,feeding pattern,environment,nutrition and other factors.By changing the fat deposition in yak muscle,the quality and taste of yak meat can be improved.Yak is a special breed of animal in the Qinghai-Tibet Plateau and its adjacent areas and is the main source of production and living materials for local herdsmen.In this paper,the influencing factors of yak fat deposition were summarized from various aspects to promote the subsequent research on yak fat deposition and yak beef quality.
