Cl. Girard et al., Response of serum concentrations of folates to dietary supplements of folic acid given to ewes during gestation, CAN J ANIM, 79(3), 1999, pp. 387-389
Serum folates were determined during the 24 h following the ingestion of 0,
130, 280 or 520 mg of folic acid at 12, 61 and 131 d of gestation in 38 ew
es. The response of serum folates increased with the dose ingested (P < 0.0
001) but decreased as gestation progressed (P < 0.005).
