Blood parameters and apparent digestibility of concentrate with rice oil for horses

Apparent digestibility coefficients and serum parameters were measured to evaluate the effect of supplementing feed concentrates with rice bran oil in horses. Twelve horses (6 males and 6 females) with a mean age of 18 ± 4 months old and mean live weight of 306 ± 22.6 kg were used. Treatments consisted of increasing rice bran oil concentrate levels of 0, 3.5, 7.0, 10.5, 14.0 and 17.5%, considering a daily intake of 2.25% live weight on a dry matter basis. A dietary effect of supplementation on the apparent digestibility of gross energy (y = 64.55 - 0.58x) was observed (P 0.05). Supplementation did not affect serum glucose levels (P>0.05), but cholesterol was affected (P 0.05). A dietary effect on the triglyceride (y = 15.73 - 0.96x + 0.0524x2) and HDL (high-density lipoprotein) (y = 45.24 + 1.0499x) parameters was observed (P<0.01). While the use of rice bran oil does affect blood parameters associated with lipid metabolism, rice bran oil levels up to 17.5% concentrate do not negatively affect the apparent digestibility of dietary nutrients.
