The deposition of dietary supplemented folic acid (FA) into the chicken egg is likely regulated by its absorption in the intestine. Therefore, factors affecting the intestinal transport of FA in the laying hen may influence the level of egg folate concentrations. To this end, a series of experiments using intestinal everted sacs were conducted to characterize the different aspects of the intest...

The effect of vitamin D source and time of feeding 25-OH vitamin D3 (HyD r ) on broiler production efficiency and carcass composition was studied. The first hydroxylation of vitamin D in the liver results in 25-OH vitamin D3 (25-OHD3); providing dietary 25-OHD3 to the bird reduces the need for this hydroxylation, potentially allowing for a more efficient use of vitamin D. The dietary treatments...
