The pregnant rats were fed a diet containing DBP (99% pure, Tokyo Kasei Kogyo, Tokyo, Japan) at a dose of 0.5, 1.0 or 2.0% ad libitum on day 11 though day 21 of pregnancy.

No independent confirmation of chemical purity or identity. The diet containing DBP was prepared fresh weekly. A predetermined amount of DBP was weighed and added to a small aliquot of ground basal diet and hand-blended. Average daily intake of DBP was calculated by the method described by Tyl et al. (1988). The control rats were fed a basal diet only ad libitum.
