Excerpt from The Nutritive Value of the Nonprotein of Feeding Stuffs Voltz' has reported three series of experiments upon dogs. In the first he compared the effect of adding to the basal ration consumed b a mature dog, on the one hand, 1 gram of nitrogen in the form Of protein of various kinds and on the other hand one-half gram in the form of protein and the remainder as asparagin. As regards the rel ative values of the proteins, the experiments are open to the criticism that the protein content of the basal ration was too high. The latter contained -to gram total nitrogen per kilogram live weight, as compared with the to gram per kilogram which apparently suffices for maintenance.2 In other words, surplus protein was being katabolized in the body in these experiments. It is not surprising to find, therefore, that the effects upon the nitrogen balance of adding more protein to the ration were irregular and difficult to interpret. The asparagin, however, in every case was found to be inferior to protein in its power of maintaining or increasing the body protein. It may be noted also in passing that the asparagin increased the nitro gen content of the feces. If we may judge from the results upon herbivora, to be considered subsequently, this may be ascribed to an increase in the so-called metabolic products, especially mucus and epithelial detritus.
