Short summary
Heat stress is a global issue that negatively affects the performance of farm animals. In this study, we investigated the effects of zinc from an organic source on some performance parameters of broiler chickens. We demonstrated organic zinc supplementation at a rate of 100 % of the organic zinc in the basal diet of broilers under hot conditions improved villus height and absorptive surface area in the duodenum and jejunum and increased the percentage of intestinal weight vs. body weight.
