Abstract
Effect of mixed oil on C<sub>18</sub> - fatty acid and conjugated linoleic acid profiles in rumen fluid and blood plasma of cattle
Highlights
Research efforts have been intensified to increase the content of conjugated linoleic acid (CLA) in meat and milk products due to its potential health benefits such as cancer prevention and multiple important physiological effects
This study was conducted to examine the effect of different levels of the mixed oil on C18fatty acid and CLA profiles in rumen fluid and blood plasma in order to find the optimal supplement level for increasing the contents of CLA in Yanbian cattle
We found that the contents of C3 were all increased at different collection times because of the supplemented mixed oil
Summary
Research efforts have been intensified to increase the content of conjugated linoleic acid (CLA) in meat and milk products due to its potential health benefits such as cancer prevention and multiple important physiological effects. It has been reported that an important factor affecting CLA products is the concentration of C18:2 in the diet. Supplementation of vegetable oil to the diet has proved to affect the CLA content of ruminant products. We added a mixed oil containing soya bean oil, safflower oil and sunflower oil, all of which are abundant in C18:2. This study was conducted to examine the effect of different levels of the mixed oil on C18fatty acid and CLA profiles in rumen fluid and blood plasma in order to find the optimal supplement level for increasing the contents of CLA in Yanbian cattle.
