The influence of a Mg-deficient diet on blood pressure and various hormonal systems was examined in Wistar rats (WR) and spontaneously hypertensive rats (SHR). The WR and SHR were individually divided into 2 groups. The Mg-deficient diet was given to one group, and a Mg-containing diet was given to the other group for 3 weeks. During this experimental period, the body weight, blood pressure, ur...

Diethylstilbestrol (DES) has been associated with vaginal neoplasia and malformations in humans. We have studied a test population of 504 female Wistar rats given diethylstilbestrol at from 0.0 to 0.5 mg/kg maternal body weight on days 18, 19, and 20 of gestation. Animals were euthanized in extremis, or at 2 years of age. The incidence of vaginal epithelial tumors was dose related. The types of...

The objective of this study was to evaluate the effects of Rumensin and Tylan in feedlot diets containing wet distillers grains plus solubles. Eight hundred beef steers (329 ± 25 kg) were blocked by initial BW and randomly assigned to one of five treatments (20 steers per pen, 8 pens per treatment). Treatments consisted of a corn-based diet with Rumensin and Tylan (CORN+RT) and four treatments ...
