Thus, our aim in this study is to examine whether nutritional supplementation (probiotics and clove essential oils) will help mitigate the negative effect of heat stress on the bird by modifying the microbial content, boosting immunity, oxidative status, metabolic, and growth. In this study, three hundred one-day-old broiler chicks (Ross 308) were fed the following experimental diet: (CON) basal diet (control diet); (CEO) CON with clove essential oils (300\u00a0mg\/kg); (PRO) CON with probiotics (2\u00a0g\/kg); (PC) CON with probiotics and clove essential oils. Our results showed a significant improvement (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.05) in body weight gain, feed conversion ratio, nutrient digestibility, and digestive enzymes activities in broilers fed on PC, CEO, and PRO compared to the control group. Moreover, a significant decrease was recorded in the abdominal fat content and an increase in the relative weight of bursa of Fabricius, and higher antibody levels against Newcastle disease virus, as well as, there was an increase (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.05) in interleukin 10 (IL-10) in all treated groups. Meanwhile, there was a decrease in tumor necrosis factor-\u03b1 (TNF-\u03b1) in all supplemented groups compared with the control group. Serum triglycerides, cholesterol, low-density lipoprotein concentrations, and alanine aminotransferase activities were significantly lower in the treated groups. Superoxide dismutase and glutathione peroxidase levels were elevated (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.05) and the malondialdehyde level value significantly decreased in all supplemented groups. The treated groups enhanced the ileum structure by increasing\n                    <jats:italic>Lactobacillus<\/jats:italic>\n                    , decreasing\n                    <jats:italic>E. coli<\/jats:italic>\n                    , and improving the morphometrically (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.05). This study strongly suggests that clove essential oil and probiotic mixture can be used as a feed supplement to reduce the effects of heat stress by improving the growth performance and enhancing immuno-antioxidant status, ileum morphometric, as well as modifying the microbial community structure of the ileum of broilers.\n                  <\/jats:p>","DOI":"10.1038\/s41598-023-45868-9","type":"journal-article","created":{"date-parts":[[2023,11,1]],"date-time":"2023-11-01T12:04:13Z","timestamp":1698840253000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Effectiveness of probiotics and clove essential oils in improving growth performance, immuno-antioxidant status, ileum morphometric, and microbial community structure for heat-stressed broilers"],"prefix":"10.1038","volume":"13","author":[{"given":"Ahmed M.","family":"Elbaz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eman S.","family":"Ashmawy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Safaa A.
