A total of 490 seven\u2010day\u2010old Arbor Acres chicks were randomly distributed into 7 experimental groups each in 10 replicates of 7 birds each. The groups were control, 500\u00a0ppb Cr<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>, 1,000\u00a0ppb Cr<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>, 500\u00a0ppb Cr\u2010Met, 1,000\u00a0ppb Cr\u2010Met, 500\u00a0ppb Cr\u2010yeast, and 1,000\u00a0ppb Cr\u2010yeast. The results showed significant superiority of the organic chromium sources (Cr\u2010Met or Cr\u2010yeast) concerning body weight and weight gain, the group supplemented with 1,000\u00a0ppb Cr\u2010yeast consumed the lowest feed (3,185\u00a0g) and had the best feed conversion ratio (1.60) compared to the control (1.73). The chromium treatments recorded significantly better protein and lipid profile, antioxidant status, and immunological parameters than the control group. Similarly, dietary chromium supplementation increased carcass yield and decreased intestinal pathogenic bacteria. In conclusion, supplementing broiler diets with organic chromium sources at 1,000\u00a0ppb promotes growth performance, physiological traits, and carcass characteristics; such chromium treatments enhanced the antioxidant status and immunity levels of broilers.<\/jats:p>","DOI":"10.1111\/asj.13448","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T06:26:02Z","timestamp":1598595962000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effects of different sources and levels of dietary chromium supplementation on performance of broiler chicks"],"prefix":"10.1111","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0622-318X","authenticated-orcid":false,"given":"Assem Mohamed","family":"Safwat","sequence":"first","affiliation":[{"name":"Poultry Production Department Faculty of Agriculture (El\u2010Shatby) Alexandria University Alexandria Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4995-0213","authenticated-orcid":false,"given":"Asmaa Shawkey","family":"Elnaggar","sequence":"additional","affiliation":[{"name":"Animal and Poultry Production Department Faculty of Agriculture Damanhour University Damanhour Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4196-3965","authenticated-orcid":false,"given":"Osama Ahmed","family":"Elghalid","sequence":"additional","affiliation":[{"name":"Poultry Production Department Faculty of Agriculture (El\u2010Shatby) Alexandria University Alexandria Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0416-9367","authenticated-orcid":false,"given":"Waleed Salah","family":"EL\u2010Tahawy","sequence":"additional","affiliation":[{"name":"Animal and Poultry Production Department Faculty of Agriculture Damanhour University Damanhour Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,20]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"267","volume-title":"Biotechnology in feed industry","author":"Anderson R.
