OLIVEIRA, R.N. et al. Hematological and biochemical evaluation of horses supplemented with semi-refined rice oil enriched with gamma orizanol. Arq. Bras. Med. Vet. Zootec. [online]. 2010, vol.62, n.5, pp. 1043-1047. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352010000500004.
The effect of the supplementation with rice oil was evaluated on the weight and hematologic profile of equines submitted moderate physical exercise. Fourteen male equines, averaging 411kg, were distributed into treated group (GT; n=7), supplemented daily with rice oil added to the diet (0.5ml/kg/BW); and control group (GC; n=7), treated with soybean oil (0.5ml/kg/BW). Three evaluations were made before the treatment, and 20 and 40 days after the beginning of the treatment, consisting of the determination of the weight, the clinical examination, and the collection of blood samples before and after the exercise for hematocrit, hemogram, glucose, lactate, and total protein determinations. There was no difference between the groups, neither between evaluations for weight nor total protein. The glucose increased significantly after the exercise in the second collection in the GC and in the third in the GT. The GC lactate increased significantly in the collections after exercise; while in the GT, the results were similar before and after treatments. The supplementation of the diet with rice oil was determinant to hinder the lactate increase in the animals submitted to exercise, what could be relevant to increase their athletic performance.
