FOODS— ANIMAL PRODUCTION. 



The influence of the addition of fat and starch to a ration 

 upon the digestibility of the nutrients of the food and upon the 

 metabolism of nitrogen, A. Wicke and H. Weiske {^Ztschr. physiol. 

 Cliem., J2:J (1896), ^^o. 2, pp. 137-152). 



Synopsis. — In an experiment with sheep it was found that the addition of starch to 

 the ration diuiinished the digestiltility of ]>rotcin and fat; the addition of fat 

 did not aftect the digestibility and resorption of protein and fat, but diminished 

 that of nitrogen-free extract. Starch was found to be a better i)rotector of 

 protein than isodynamic quantities of fat. 



The expeiiuient, wliich is a coiitinuatioii of work previously reported,' 

 was made with 2 sheep weighing 52 k,u. and 41 kg., respectively. The 



iZtschr. physiol. Chem., 21 (18!).")), p. 42 (E. S. R., 7, p. 336).
