Description:
When hens are raised to sexual maturity from hatching with 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] as their sole source of cholecalciferol (vitamin D3), fertile eggs appear to develop normally but fail to hatch. When hens receive a combination of 1,25(OH)2D3 and 24R,25-dihydroxyvitamin D3 [24,25(OH)2D3], hatchability equivalent to that with hens given vitamin D3 is obtained. These results suggest a biological role for 24,25(OH)2D3 not previously recognized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henry, H L -- Norman, A W -- New York, N.Y. -- Science. 1978 Sep 1;201(4358):835-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/684411" target="_blank"〉PubMed〈/a〉
