The T-RFLP research method in the study of rumen microbiota in dairy cows with subclinical ketosis
The article presents the results of researches related to the study of the possibility of using the modern molecular genetics method -T-RFLP-analysis (terminal restriction fragment length polymorphism) to identify the community of microorganisms in the contents of the rumen in clinically healthy highly productive cows and cows with subclinical ketosis. The research methodology is based on the analysis of the conservative regions in the microorganisms’ genome variability. The results showed the high efficiency of the method used for the identification of microorganisms in the rumen contents in the studied animals. A large community of bacteria, archaea, protozoa and anaerobic fungi is determined in the rumen contents from highly productive cows with subclinical ketosis. The data obtained allow us to significantly amplify the information on the pathogenesis of subclinical ketosis in cows with high milk productivity. The presence of conditionally pathogenic and pathogenic microflora in sick cows in the rumen contents indicates a violation of rumen digestion, which leads to the development of concomitant non-contagious diseases in animals
