Abstract:

There are a large number and variety of microorganisms inhabiting the rumen tract of dairy cows, forming a 'mutually beneficial' symbiotic relationship with the body. Short-chain fatty acids (SCFAs), as metabolites of microorganisms, interact with microorganisms to provide nutrients to the body and maintain the stability of the internal environment. This paper describes the interactions between SCFAs and microorganisms in the rumen tract of dairy cows, focuses on their effects on the health and homeostasis of the rumen tract of dairy cows, and reviews the mechanisms of SCFAs in rumen of dairy cows regulating the internal environment, so as to provide theoretical basis for the nutritional regulation of the health of dairy cows by SCFAs.

Key words: short-chain fatty acids, rumen microbes, interactions, homeostasis
