Effects of 25‐hydroxyvitamin D3 on growth performance, serum parameters, fecal microbiota, and metabolites in weaned piglets fed diets with low calcium and phosphorus

BACKGROUND With the development of intensive farming, long‐term exposure of pigs to poor light conditions is not conducive to the production of vitamin D3, and vitamin D3 deficiency could affect absorption and metabolism of calcium (Ca) and phosphorus (P). 25‐Hydroxyvitamin D3 (25OHD3) has higher bi...

Description
Summary:BACKGROUND With the development of intensive farming, long‐term exposure of pigs to poor light conditions is not conducive to the production of vitamin D3, and vitamin D3 deficiency could affect absorption and metabolism of calcium (Ca) and phosphorus (P). 25‐Hydroxyvitamin D3 (25OHD3) has higher bioactivity than regular vitamin D3. This study investigated the effects of 25OHD3 on performance, serum parameters, fecal microbiota, and metabolites in weaned piglets fed with low Ca‐P diet. RESULTS It was found that a low Ca‐P diet supplemented with 50 μg/kg 25OHD3 (NC + 25‐D) improved (P
