牛奶中乳脂率影响因素研究

Study on the Infulencing Factors of Milk Fat Percentage

近年来我国奶牛养殖行业发展迅速,人们在专注于提高奶牛产奶量的同时,开始关注如何提高乳品质。乳脂是牛乳的主要营养成分,也是一种高质量的天然脂肪。乳脂率是衡量牛奶品质优劣的关键指标,同时也是制约中国奶业发展的重要因素,如何提高乳脂率一直是行业研究热点。本文从遗传因素和饲养环境、奶牛生理状况、季节等非遗传因素方面阐述了其对乳脂率的影响,以期为提高乳脂率的研究提供一定理论基础。

In recent years,the dairy farming industry in China has developed rapidly,people pay attention to how to improve the quality of dairy cows while focusing on improving the milk yield.Milk fat is a kind of natural fat and a main nutritional component of milk.Milk fat percentage is an important index to evaluate milk quality.Therefore,the research hotspot of the industry has always been how to improve the milk fat rate.This article mainly expounds on the effects of genetic factors and non-genetic factors such as feeding environment,physiological status of dairy cows,and seasons on milk fat percentage,in order to provide a theoretical basis for the study of improving milk fat percentage.
