Digestibility

Effects of concentration of calcium and phosphorus and 1-alpha-hydroxycholecalciferol (1-α-OH-D3) on digestibility and retention of calcium and phosphorus and concentration of digestible energy in diets fed to sows in late-gestation

Absorption of Ca and P by active transport in the small intestine is regulated by calcitriol, which is the active form of vitamin D (1,25-dihydroxycholecalciferol) and the hormones calcitonin and PTH. One-alpha-hydroxycholecalciferol (1-α-OH-D3) is an active vitamin D3 analog that does not require the second hydroxylation step for vitamin D3 to be active. It is possible that supplementation of 1-α-OH-D3 may increase absorption of Ca and P.

The requirement for Ca and P by gestating sows increases in late gestation compared with early- and mid-gestation because of increased needs by the developing fetuses. It is also possible that dietary concentrations of Ca and P affect the rate of absorption of Ca and P in sows but data to demonstrate this have not been reported. Therefore, the objective of this experiment was to test the hypothesis that the Ca and P concentrations in diets fed to gestating sows in late gestation and supplementation of 1-α-OH-D3 affect apparent total tract digestibility (ATTD) and retention of Ca and P as well as the ATTD of GE and concentration of DE in diets. The second hypothesis was that there is an interaction between dietary Ca and P concentrations and supplementation of 1-α-OH-D3 in diets fed to gestating sows.
