This study examined the effects of different vegetable oil sources on the Fatty Acid (FA)
composition of muscle and performance of beef steer twenty one steers (384±17 kg BW) were
assigned in seven treatment that fed diets containing 0% oil (control), 2 and 4% of Canola Oil (CO), Sunflower
Oil (SO) and Restaurant Waste Oils (RWO).
steers fed
Ribeye steaks from steers fed CO, SO and RWO for 90 days of
experiment were used after slaughtering to evaluate
the effects of oil source on fatty acid composition. Amounts
of muscle saturated FAs decreased and polyunsaturated FAs increased in both 2% CO and 2% SO groups.
The highest contents of Total n-3, n-6 and n-7 FAs were significantly (p
