Fatty acids composition of rumen bacteria and protozoa in cows fed diet with different concetrates level and sodium bicarbonate addition

O. V. Golubets, I. V. Vudmaska

The effect of forage to concentrate ratio change with and without of buffer addition in the diets of dairy cows on fatty acids composition of rumen bacteria and protozoa were investigated. Increasing of content of concentrate in diets of cows have resulted to increasing of level of trans-isomers C 18:1 while sum quantity of C 18:1 was not changed. Mass part of trans-isomers C 18:1 in lipids of bacteria was higher in cows fed by a diet with a large content of concentrate with buffer than in animal of control group, but lower than in cows of experimental group without buffer addition. In the cells of rumen protozoa was founded much more conjugated linoleic acids and its metabolites than in the bacteria.
