Short summary
The present study addressed the interactive effects of concentrate levels (low (40 %) and high (60 %)) and plant (pomegranate, garlic, or sunflower) oils on in vitro rumen fermentation kinetics. Results indicated that the interaction of diet and oils had no significant effect on in vitro gas production parameters. Data suggested no effect for unconventional oil on in vitro rumen fermentation in either high or low concentrate diets.
