1,25-Dihydroxycholecalciferol Improved the Growth Performance and Upregulated the Calcium Transporter Gene Expression Levels in the Small Intestine of Broiler Chickens.

ABSTRACT: 1,25-Dihydroxycholecalciferol (1,25-(OH)₂-D₃) is the final active product of vitamin D. This study aimed to investigate the effects of 1,25-(OH)₂-D₃ on growth performance, bone development, and calcium (Ca) transporter gene expression levels in the small intestine of broiler chickens. On the day of hatching, 140 female Ross 308 broilers were randomly allotted into two treatments with five replicates (14 birds per replicate). Two levels of 1,25-(OH)₂-D₃ (0 and 1.25 µg/kg) were added to the basal diet without vitamin D. Results showed that the addition of 1.25 µg/kg 1,25-(OH)₂-D₃ increased the average daily feed intake and the average daily gain and decreased the feed conversion ratio and mortality in 1-
