母牛体内生殖激素变化规律的研究进展

生殖激素是对母牛繁殖活动起直接调节作用的激素，因此对其进行精准测定，掌握生殖激素的变化规律对生产上提高母牛繁殖效率具有重要意义。但在动物体内大部分生殖激素的含量是极其微量的，所以选择准确灵敏的测定方法非常重要。本文论述生殖激素的生物测定法、受体分析法、免疫测定法（放射免疫测定和酶免疫测定）的优缺点，同时对各生殖激素的来源、生理作用和变化规律，及各激素之间的相关性分析做阐述，将对研究母牛的生殖生理，提高母牛繁殖效率，促进高产、高效、优质的牛业生产，加快牛业繁殖改良进程有着极其重要的意义。

Research Progress of Reproductive Hormone Changes in Dairy Cows

Reproductive hormones are hormones that directly regulate the reproductive activities of cows. Therefore, it is of great significance to accurately determine it and master the change law of reproductive hormone to improve the reproductive efficiency of cows in production. However, the content of most reproductive hormones in animals is extremely small, so it is very important to choose an accurate and sensitive determination method. This paper discusses the advantages and disadvantages of bioassay, receptor analysis and immunoassay (radioimmunoassay and enzyme immunoassay) of reproductive hormones. At the same time, it expounds the source, physiological function and change law of reproductive hormones, as well as the correlation analysis between hormones. It will be helpful to study the reproductive physiology of cows, improve the reproductive efficiency of cows, and promote high-yield, efficient and high-quality cattle production, It is of great significance to speed up the breeding and improvement process of cattle industry.
