The levels of vitamin A in the starter and grower diets of the control group were 7168 and 5213 IU\/kg diet, but &lt;1000 IU\/kg in the experimental ones. Vitamin A and uric acid contents were measured in the serum, while liver samples were taken to determine the vitamin A content. Parts of the central nervous system and some internal organs were examined histologically. In the sixth week, ruffled feathers and uncoordinated gait were the earliest signs seen in the experimental group. The vitamin A content in the liver samples significantly decreased in the experimental group (0.09 mg\/kg vs. 29.5 mg\/kg). The serum level of uric acid in the experimental group was significantly higher (12.8 mg\/dL vs. 3.38 mg\/dL). Birds in the experimental group showed squamous metaplasia in the oesophagus. No histopathological alterations were seen in the central nervous system. The elevated uric acid level in the serum is worth mentioning.<\/jats:p>","DOI":"10.3390\/vetsci4040049","type":"journal-article","created":{"date-parts":[[2017,10,2]],"date-time":"2017-10-02T13:10:05Z","timestamp":1506949805000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Outcome of an Experimental Study in Growing Turkeys Suspected of Having a Diet Related, Uncommon and Uncoordinated Gait"],"prefix":"10.3390","volume":"4","author":[{"given":"Amr","family":"Abd El-Wahab","sequence":"first","affiliation":[{"name":"Department of Nutrition and Nutritional Deficiency Diseases, Faculty of Veterinary Medicine, Mansoura University, Mansoura 35516, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Visscher","sequence":"additional","affiliation":[{"name":"Institute for Animal Nutrition, University of Veterinary Medicine Hannover, Foundation, Hannover 30173, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Ratert","sequence":"additional","affiliation":[{"name":"Institute for Animal Nutrition, University of Veterinary Medicine Hannover, Foundation, Hannover 30173, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mareike","family":"K\u00f6lln","sequence":"additional","affiliation":[{"name":"Institute for Animal Nutrition, University of Veterinary Medicine Hannover, Foundation, Hannover 30173, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Diephaus","sequence":"additional","affiliation":[{"name":"Tierarztpraxis Am Dorfteich, Cloppenburg 49661, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrease","family":"Beineke","sequence":"additional","affiliation":[{"name":"Institute for Pathology, University of Veterinary Medicine Hannover, Foundation, 30559, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josef","family":"Kamphues","sequence":"additional","affiliation":[{"name":"Institute for Animal Nutrition, University of Veterinary Medicine Hannover, Foundation, Hannover 30173, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1177\/104063870601800514","article-title":"Vitamin A deficiency in turkey poults","volume":"18","author":"Cortes","year":"2006","journal-title":"J.
