Summary: This study aimed to evaluate the estrous behavior, ovarian activity, feed intake, metabolic and physiological parameters of Canind ?e goats supplemented for nine days with Licuri oil (Syagrus coronata). Thirty-six adult fe- male goats were distributed randomly into two groups: control group (n = 18) without Licuri oil and the oil group (n = 18) receiving a supplement containing 3% Licuri oil. The short-term food supplementation was associated with an estrus synchronization protocol. The number of ovulations and follicle diameter were eval- uated by ultrasonography. Dry matter intake (DMI) and nutrient intake, water ingestion, and physiological parameters such as rectal temperature (RT), respiratory rate (RR), heart rate (HR), and serum concentrations of cholesterol and non-esterified fatty acids (NEFA) were also determined. As concern statistical analysis, ANOVA followed by Fisher?s LSD was used and the differences were considered significant when P < 0.05. The control group showed higher HR and RR in the afternoon shift compared to the Oil group. The Oil group showed lower DMI but higher ether extract intake, and serum cholesterol and NEFA concentration than control group. Treatments did not affect estrus response and ovulation rate, but the Licuri oil increased the number of small follicles. The supplementation of Licuri oil improved thermal comfort during the dry season and a marginal increase in the ovarian activity was observed.
