RELATIVE VALUES OF FEEDING STUFFS

On the other hand, the effect of protein in increasing the di- 

 gestibility of the non-nitrogenous ingredients of rations contain- 

 ing an excess of carbohydrates is shared also by the non-pro- 

 teins, such comparatively simple substances as asparagin or 

 even ammonium salts having in a number of instances exerted 

 a marked influence of this sort. 



729. Influence of drying. The simple removal of water 

 from a feeding stuff affects its digestibility but slightly. Weiske l 

 compared the digestibility of green and dried alfalfa and espar- 

 cet by sheep. In these experiments the forage was mowed 

 daily, one-half of it fed and the other half dried without loss, 

 which was a comparatively easy task with the relatively small 

 amounts to be handled. In the second half of the experiment 

 the portions of dried forage were fed to the same animals in the
