tiling is true of other liiglily nitrogenous bye-fodders, e. g,^ 

 all kinds of oil cake, the legumes, brewers' grains, etc. 



The results of these determinations of the digestibility 

 of bye-fodders are included in Table II. of the Appendix. 

 As the general result of the experiments, we can say that 

 nitrogenous lye-fodders do not deemme the digestibility of 

 the coarse fodder with which they are med. 



The G-rains. — The influence of the grains, i. e,^ of con- 

 centrated fodders with a medium nutritive ratio (1 : 5-8), 

 on the digestibility of coarse fodders has received compar- 

 atively little attention, 



Oats have been the subject of experiments by Ilof- 

 meister &IIaubner* and by Wolff f on sheep. In both 

 investigations it was fomid that an addition of oats to 

 the coarse fodder did not essentially alter its digestibility. 

 Wolff obtained the following results, on the assumption 

 that the digestibility of the coarse fodder (hay) was not 

 altered :

 Batio of feay to oats. Pot cent. 



1 : 1,76 78 



1 : 8 09 78 4 



1 : 3 30 78 5 



The constancy of the digestion coefficient for oats shows, 

 as explained above, that the assumption of unaltered diges- 

 tibility of the coarse fodder is probably correct, and can at 

 least serve as a basis for the calculation of rations. Ilof- 

 meister & Ilaubner's results were, on the same assumption, 

 as follows :
