Adverse effects of heat stress on intestinal integrity may account for reported higher translocation of Salmonella enteritidis, resulting in intestinal inflammation and increased Salmonella counts in tissues after heat stress. Additionally, nutrient digestibility was reduced during heat stress, which supports the need to use feed ingredients with a higher digestibility (and therefore dietary nutrient concentration will require the use of high quality feedstuffs) or feed additives that support nutrient digestion.
