The use of essential oils in the diet of cattle and their mechanisms are being extensively studied, such as the use of castor oil and cashew. Thus, the objective - to evaluate the effects of essential oils of castor and cashew in mineral supplementation of cattle kept on pasture Brachiariabrizantha in the state of Tocantins. The animals were weighed and randomly divided into two groups at the beginning of the experimental period totaling 60 days between the months of September and November, with 60 cattle at the time of the yearling (15 months) each group. The pasture had good availability of leaf mass, but drought. The control group received no supplement mineral oils + pasture + water ad libitum. The treatment group received mineral supplement with essential oils (2.43 g / animal / day) + pasture + water ad libitum. Statistical analyzes were performed by SAS statistical software and means were compared by t-test (p <0.05). The mineral supplement intake was higher in the treatment group (180g/animal/dia) than the control group (165g/animal/dia). The inclusion of supplementation on essential oils promoted average weight gain of 17.36 kg versus 6.53 kg for the control group throughout the experimental period. There was a statistical difference (p <0.05) between the two treatments.
