The animals got an eating routine including great maize silage with a higher dry matter substance (16 kg), clover-grass haylage (l6 kg), meadow roughage (3 kg) and advantageous feed mix (7.5 kg). The allocates were dealt with to cows as complete mixed extent. In preliminary social events, the yeast culture was added into the feed mix in proportions of 2, 4, 6, 8, 10 g every day and animal. Trial of rumen fluid were required perorally 3–4 hours following dealing with. The procured results exhibited that the extension of a Saccharomyces cerevisiae SC-47 culture in proposed segments showed a productive result on ruminal handling. As differentiated and control, the development of all recently referenced proportions of the yeast culture into the dealing with distribute achieved all cases in a quantifiably basic (P < 0.01) decrease in pH and swayed near the lower farthest reaches of the reference regards. As differentiated and control, the yeast culture supplementation showed a valuable result (P < 0.01) on production of shaky unsaturated fats (VFA) (127.6 versus 84.0 mmol/l). The use of soluble base was higher (P < 0.01) in preliminary social occasions (8.12, resp. 8.68 mmol/l) than in controls (9.06 mmol/l). The qualification in protozoa numbers in rumens of dairy cows in the control and test packs was quantifiably especially through and through (P < 0.01) extraordinary. There was a comfortable association between the part of yeast culture from one perspective and the VFA content and protozoa numbers on the other. The backslide examination of dependence of ward variable (for instance pH of rumen fluid) on the independent one (for instance the piece of yeast culture) uncovered only a slight degree of dependence (r = 0.671).
