AvcrcKje Drj and Digesslible Nutricnlfi in Daily Rations {Pounds). 



The licrtl averaged about 900 pounds in weight. The amount 

 of dry matter and of total digestible nutrients fed in each ration 

 was substantially the same; the high-protein ration contained 

 about .4 of a pound more digestible protein than the low-protein 

 ration. The excess over the low-protein ration is not marked 

 and is very much less than that fed in experiments I. and II. , 

 previously mentioned. 



Both rations caused a gain in weight, the excess being in 

 favor of the high-protein ration. This may have been ex- 

 pected, as the low-protein ration had rather too wide a ratio 

 to be productive of the best results.
