To evaluate the phytobiotic effect of Anacardium occidentale leaf powder (AOLP) on growth performance, diarrhea incidence, blood biochemistry, and intestinal traits, seventy-two weaned piglets were randomly distributed into four groups (six replicates/group and three pigs/replicate) for 28 days, receiving a control diet (T0) or being supplemented with 5 (T1), 10 (T2), or 15 (T3) g/kg of AOLP. The diets did not affect the growth performance (p >: 0.05): however, the AOLP groups had a decreased diarrhea incidence and malondialdehyde concentration (p <: 0.05: 28 days). However, the AOLP groups had increased immunoglobulins (G and M) and villus heights (p <: 0.05) in the duodenum. Likewise, T3 improved the number of goblet cells in the villi and the whole intestine (p <: 0.01), the Mucin2 area in the jejunum and ileum (p <: 0.05), occludin gene expression in the jejunum (p <: 0.01), and acetic and valeric acid production (p <: 0.05). Microbial diversity at the genus level was not different (p >: 0.05): however, T3 increased the abundance of the Lactobacillus genus. These findings suggest that dietary supplementation with AOLP improved intestinal health by increasing antioxidant, immune, anti-inflammatory, and antidiarrheal activity in the weaned piglets.
