| Abstract: | Atlantic salmon Salmo salar were given three dietary doses of vitamin D3 for a period of 11 weeks: diet groups I, II and III received a 0.04, 2.21 and 28.68 μg g−1 diet of vitamin D3, respectively. The tissue distribution of vitamin D3 was investigated, and between diet groups II and III, the level of vitamin D3 found in the tissues was increased by a factor similar to the increased level in the feed. No effects were observed on weight gain, survival, plasma level of calcium, red blood cell count or haematocrit, relative to the dietary levels of vitamin D3. The results showed that while the plasma concentration of 25(OH)D3 increased between diet groups II and III, the concentration of 1,25(OH)2D3 decreased. |
