Resumo: 	ABSTRACT This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats. Eight Anglo Nubian goats were used, which were distributed in a double 4 × 4 Latin square experimental design (four periods and four levels of buriti oil) replacing corn in the total dry matter. For the evaluation of feeding behavior, single animals were observed every ten minutes for 24 h on three days. Respiratory rate (RR), heart rate (HR), rectal temperature (RT), and sweating rate (SR) of the animals were evaluated in the morning (09:00 h) and in the afternoon (15:00 h). Blood samples were always taken in the morning, before feeding, by puncturing the jugular vein for the complete blood count and white blood cell count. The levels of buriti oil had no effect on feeding, rumination, idling time, water intake, defecation and urination, DM intake, feed efficiency, and rumination efficiency of DM and NDF, but had effects on NDF intake. Physiological variables (RT, SR, RR, and HR) in both periods of the day were not influenced by the inclusion of buriti oil. However, SR and RR were higher in the afternoon than in the morning. In erythrocyte, results showed that the hematocrit and mean corpuscular volume increased with the inclusion of buriti oil. Hemoglobin, red blood cell count, mean corpuscular hemoglobin concentration, and total plasma protein were not affected by the inclusion of buriti in the goat diet. The inclusion of buriti oil is recommended in up to 45 g kg−1 (DM basis) as a replacement for ground corn in diet of lactating goats without affecting the feeding behavior and physiological and hematological variables.
