To evaluate the antidiarrheal effects of Anacardium occidentale L. leaf powder, 45 two-day old White Leghorn hybrid chicks (L-33) were used for 8 hours, in a completely randomized design with three treatments was applied. The feed treatments consisted in basal diet (BD), BD + 1.0 % of Anacardium occidentale L. leaf powder, and BD + 1.5 % of A. occidentale leaf powder. The consumption of feeds accumulated and the initial and final live weights were determined. Besides, the incidence of diarrhea was calculated at 2, 4, 6 and 8 hours after inducing diarrhea with castor oil. Then, five birds were sacrificed per treatment and the accessory organs of the immune system, and the viscera were weighed. The intestinal pH was analyzed and the hematocrit levels were measured. The initial and final live weights, and feed consumption of the newborn diarrheal birds remained stable (P > 0.05) among the treatments. Likewise, the liver, glandular stomach, muscular stomach, small and large intestine relative weights, and the intestinal pH did not have statistically significant variations (P > 0.05). Nevertheless, supplementation with the medicinal powder changed (P < 0.05) the relative weight of the pancreas, heart, thymus and bursa of Fabricius. The T2 treatment (1.5 %) decreased the incidence of diarrhea significantly (P < 0.05) compared to the other treatments. However, the experimental treatments did not alter (P > 0.05) the concentration of hematocrits in newborn birds. Supplementation of 1.5 % of Anacardium occidentale L. leaf powder is recommended for use in newborn birds with metabolic diarrhea
