牛奶体细胞生成与乳品质量和安全的关系

牛奶体细胞数是反映奶牛乳房健康状况的重要指标之一,该指标偏高意味着奶牛可能处于亚健康或疾病状态。在奶牛正常生理状态下,牛奶体细胞的组成和数量都是基本稳定的,而当乳房外伤或疾病(如乳房炎等)发生时,牛奶体细胞数增多,产奶量降低,乳品质量下降。牛奶的品质关系到消费者的健康,因此,确保生鲜乳的质量安全是奶牛养殖工作者必须着手解决的首要问题。因此,本文围绕牛奶体细胞生成与产奶量和乳品质之间的关系展开综述,为提高乳品质量安全提供理论指导。

Relationship between Milk Somatic Cell Formation and Milk Quality and Safety

Milk somatic cell count (SCC) is one of the most important indexes of the health of mammary gland in dairy cows.High milk SCC indicates a subclinical health or disease status for dairy cows.Composition and count of somatic cells are basically stable under healthy state of animals.When the mammary gland is injured or infected (such as mastitis), milk SCC will increase, and follows decreases of milk yield and quality.Milk quality is important for the health of human being.Improving the quality of raw milk has become a key objective for dairy farming industry.Therefore, this paper focused on the relationship between somatic cell formation and milk production and quality, and from which to provide theoretical guidance for improving milk quality and safety.
