The aim of the research was to study the effect of different feeding technologies on rumen pH and some microbiological parameters of dairy cows. The investigations were carried out during the indoor period with 12 Lithuanian Black and White cows fed balanced ration of the same composition. Taking into consideration feeding technologies were formed two groups of dairy cows: for the control group food was given as separate components; for the experimental - as a chopped mixer of forages prepared by a van-mixer OptiMix. Concentrates for both groups of cows were given individually. Samples of rumen fluid were taken 3 hours after morning feeding every tenth day. The duration of the experiment was 40 days. The following parameters were studied: pH (by a potenciometric method); total count of lactobacillus, total count of enterobacteria (by a plate method), and total count of bifidobacteria (by a method of limitary dilutions).
