Resum: Nutritional strategies to improve gut health of broilers are under research. This study investigated the effect of dietary supplementation with sodium butyrate protected by sodium salts of medium-chain fatty acids as a feed additive on broiler gut health. The first experiment was conducted to evaluate the effect of supplementing at 0. 5, 1, and 2 kg/t in broilers housed under optimal conditions. Supplementation at 0. 5 and 1 kg/t maintained goblet cell counts at 10 days of age (p ≤ 0. 05), and supplementation at 1 kg/t decreased intraepithelial lymphocyte counts compared to 2 kg/t at 39 days (p ≤ 0. 10). Abdominal fat pad levels of lauric and myristic acids were gradually increased by supplement dose (p ≤ 0. 05). In the second experiment, the feed additive at 1 kg/t was evaluated in coccidiosis-challenged broilers. Experimental treatments were as follows: non-challenged, control-challenged, and supplemented-challenged treatments. Coccidiosis negatively impact performance and modify histomorphometry and microbiota (p ≤ 0. 05). The feed additive increased crypt depth at 7 days post-inoculation and goblet cell count at 14 days post-inoculation (p ≤ 0. 05). Further, supplementation interacted with the microbiota modification led by the coccidiosis (p ≤ 0. 05). These results suggest that this feed additive could be a useful strategy to reinforce the gut barrier, especially for birds under coccidiosis-challenge treatments.
