Limited in vivo conversion of dietary D3 to 25-OH-D3 in rainbow trout and undetectable endogenous photo-production of D3 in indoor-raised fish

Vitamin D is essential for salmonids and is routinely supplemented in feeds as cholecalciferol (D3). As an intermediate metabolite in the in vivo conversion of D3 to active vitamin D (1,25-OH-D3), directly adding calcifediol (25-OH-D3) to feed may improve vitamin D status. An 84-day feeding trial wa...
