Description:
As shown previously, laying hens given 1,25-dihydroxyvitamin D3 as their sole source of vitamin D produce fertile eggs having normal shells, but only 35 to 55 percent of the embryos are normal. Giving these hens additional 25-hydroxyvitamin D3, 24,25-dihydroxyvitamin D3, or 24,24-difluoro-25-hydroxyvitamin D3 at 1.25 nanomoles per day resulted in 90 to 100 percent normal embryos, and hence, hatchability. Since 24,24-difluoro-25-hydroxyvitamin D3 cannot be 24-hydroxylated, 24-hydroxylation is not required for this function of 25-hydroxyvitamin D3.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ameenuddin, S -- Sunde, M -- DeLuca, H F -- Ikekawa, N -- Kobayashi, Y -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):451-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6979782" target="_blank"〉PubMed〈/a〉
