Variation of body nitrogen--body water ratio of Sprague-Dawley rats as a function of the dietary protein quality and quantity.
Forty-two male Sprague-Dawley rats aged 45 days were analyzed for total body nitrogen and body water, and the correlation between the body nitrogen:body water ratio according to the type and level of protein was found lowest body nitrogen:body water ratios (0.021-0.033) in rats maintained on protein-free diet, or in diets in which protein was derived from French bread. Highest body nitrogen:body water ratios were found in rats maintained on either 7.2 or 7.9% or diets, based on casein protein + dl-methionine.
