The aim of this study was to investigate the effects of UV\u2010b radiation on plasma 25\u2010hydroxyvitamin D\n                    <jats:sub>3<\/jats:sub>\n                    levels and ionised calcium concentrations in ball pythons (Python regius). Blood samples were taken from 14 ball pythons, which had never been exposed to UV\u2010b light, to obtain baseline 25\u2010hydroxyvitamin D\n                    <jats:sub>3<\/jats:sub>\n                    levels and ionised calcium concentrations. Blood samples were then taken again from the same snakes 70\u00a0days later after one group (Group 1, n=6 females) were exposed to UV\u2010b radiation daily, and the other group (Group 2, n=5\u00a0males and 3 females) were exposed to no UV\u2010b radiation. Mean\u00b1sd 25\u2010hydroxyvitamin D\n                    <jats:sub>3<\/jats:sub>\n                    levels on day 0\u00a0in Group 1 were 197\u00b135\u00a0nmol\/l, and on day 70 were 203.5\u00b113.8\u00a0nmol\/l. Mean\u00b1sd 25\u2010hydroxyvitamin D\n                    <jats:sub>3<\/jats:sub>\n                    levels in Group 2 on day 0 were 77.7\u00b141.5\u00a0nmol\/l, and on day 70 were 83.0\u00b141.9\u00a0nmol\/l. Mean\u00b1sd ionised calcium levels at day 0 were 1.84\u00b10.05\u00a0mmol\/l for Group 1, and on day 70 were 1.78\u00b10.07\u00a0mmol\/l. Mean\u00b1sd ionised calcium levels at day 0 were 1.79\u00b10.07\u00a0mmol\/l for Group 2, and on day 70 were 1.81\u00b10.05\u00a0mmol\/l. No association was demonstrated between exposure to UV\u2010b radiation and plasma 25\u2010hydroxyvitamin D\n                    <jats:sub>3<\/jats:sub>\n                    and ionised calcium concentrations. These results may provide baseline parameters for future studies in this and other snake species to determine ability to utilise UV\u2010b light for vitamin D production.\n                  <\/jats:p>","DOI":"10.1136\/vr.101555","type":"journal-article","created":{"date-parts":[[2013,9,25]],"date-time":"2013-09-25T23:51:20Z","timestamp":1380153080000},"page":"345-345","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":20,"title":["The effects of UV light on calcium metabolism in ball pythons (Python regius)"],"prefix":"10.1002","volume":"173","author":[{"given":"J.","family":"Hedley","sequence":"first","affiliation":[{"name":"Royal (Dick) School of Veterinary Studies and The Roslin Institute The University of Edinburgh Hospital for Small Animals Easter Bush Veterinary Centre Roslin Midlothian EH25 9RG UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Eatwell","sequence":"additional","affiliation":[{"name":"Royal (Dick) School of Veterinary Studies and The Roslin Institute The University of Edinburgh Hospital for Small Animals Easter Bush Veterinary Centre Roslin Midlothian EH25 9RG UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,10,12]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.67.12.2046"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.69.2.294"},{"key":"e_1_2_6_4_1","first-page":"218","volume-title":"Comparative Vertebrate Endocrinology","author":"Bentley P.
