In this study, 240 one-day-old male broiler chicks (Cobb 500) were randomly assigned to 48 battery cages. From day 1, these 48 cages were randomly subjected to four different treatment strategies: Control (wherein, their basal diet included 60 mg\/kg of ZnO), ZNONPs 40 (wherein basal diet included 40 mg\/kg of ZnONPs), ZnONPs 60 (basal diet included 60 mg\/kg of ZnONPs), and ZnONPs 100 (basal diet included 100 mg\/kg of ZnONPs). Thereafter, from day 22 to 42, the chickens from each dietary treatment group were subjected to different temperature stresses either normal (23 \u00b1 1 \u00b0C constant) or HS (34 \u00b1 1 \u00b0C for 6 h\/d), which divided them into eight different treatment groups. Our findings revealed that dietary ZnONPs altered the gene expression of cholecystokinin (ileum), heat stress proteins (HSP) 70 (jejunum and ileum), and HSP 90 (duodenum, jejunum, and ileum). The gene expression of ghrelin was affected by the interaction between the ZnONPs concentration and temperature in the duodenum and stomach. More studies are required to elucidate its complex physiological and biochemical functions of the regulation of gene expression within the intestine in heat-stressed broiler chickens.<\/jats:p>","DOI":"10.1093\/jas\/skaa300","type":"journal-article","created":{"date-parts":[[2020,9,16]],"date-time":"2020-09-16T14:07:44Z","timestamp":1600265264000},"source":"Crossref","is-referenced-by-count":18,"title":["Effects of zinc oxide nanoparticles on regulatory appetite and heat stress protein genes in broiler chickens subjected to heat stress"],"prefix":"10.1093","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0693-9436","authenticated-orcid":false,"given":"Suriya Kumari","family":"Ramiah","sequence":"first","affiliation":[{"name":"Institute of Tropical Agriculture and Food Security, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elmutaz","family":"Atta Awad","sequence":"additional","affiliation":[{"name":"Preclinical Department, Universiti Malaysia Kelantan, Pengkalan Chepa, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nur Izzah Mohd","family":"Hemly","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Faculty of Agriculture, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahdi","family":"Ebrahimi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Preclinical Sciences, Faculty of Veterinary Medicine, University Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olubodun","family":"Joshua","sequence":"additional","affiliation":[{"name":"Institute of Tropical Agriculture and Food Security, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Jamshed","sequence":"additional","affiliation":[{"name":"Institute of Tropical Agriculture and Food Security, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mookiah","family":"Saminathan","sequence":"additional","affiliation":[{"name":"Product Development and Advisory Services Division, Malaysian Palm Oil Board, Kajang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdoreza Farjam","family":"Soleimani","sequence":"additional","affiliation":[{"name":"Institute of Tropical Agriculture and Food Security, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zulkifli","family":"Idrus","sequence":"additional","affiliation":[{"name":"Institute of Tropical Agriculture and Food Security, Universiti Putra Malaysia, UPM Serdang, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"2020101708245472300_CIT0001","doi-asserted-by":"crossref","first-page":"1358","DOI":"10.3382\/ps.2008-00554","article-title":"Changes in heat shock protein 70 expression and blood characteristics in transported broiler chickens as affected by housing and early age feed restriction","volume":"88","author":"Al-Aqil","year":"2009","journal-title":"Poult.
