Abstract
Royal jelly fed to 5 vitamin E deficient pregnant [male] rats in amounts as high as 20 g. per rat during the first 5 days of gestation failed to prevent complete resorption of embryos. Bee bread was consumed by vitamin E deficient [male] rats in amounts of 25 to 37.5 g. each during the first 5 days of gestation. In 2 cases out of 10 pregnancies, 1 living embryo was found at the end of gestation. 7 rats showed complete resorption, and in 1 rat at parturition, there was 1 recently dead embryo, several partly resorbed embryos and a number of complete resorptions. The experiment indicates that royal jelly is probably devoid of vitamin E. However, this vitamin is present in bee bread, but in insignificant amounts.This publication has 1 reference indexed in Scilit:
