The Role of Boron in the Diet of the Rat.

Abstract

A synthetic diet is described which has a boron content of 163 μg per kg. This diet supports good growth and development in the rat. Food consumption compares well with that of animals on good purified diets used in this laboratory. The reproductive processes are normal. The young born to mothers on this boron-low diet appear normal and are successfully raised. Pathological studies showed the tissues of these rats to be normal. No evidence is obtained under the experimental conditions that boron is essential in the nutrition of the rat.
