ABSTRACT
The experiment was conducted to determine the effect of mixed oil on C18-fatty acid and CLA profiles in rumen fluid and plasma of Yanbian cattle by adding different levels of the mixed oil to concentrate. The contents of propionate and C18:1 were increased in rumen fluid by adding mixed oil. In plasma, the contents of C18-fatty acids in experimental groups were all significantly higher than in the control group; c9, t11-CLA increased at 6 h, t10, c12-CLA increased at 0, 9, 12 h. Enhancing CLA contents of rumen fluid and plasma through feeding 4% mixed oil in the diet seems to be the optimal level.
