MATTITAL OF CATTLE-FEEDING. 



The slight decrease in the digestibility of the protein of 

 tlie haj becomes so exceedingly small, when calculated on 

 the whole ration, as to be of no practical signiiicanee, 

 while the gluten exerted practically no influence on that 

 of the remaining nutrients. Thus, these results show not 

 only that even these large additions of albuminoids to the 

 fodder produced no essential alteration of digestibility, but 

 also tlmt the gluten was almost completely digestible. 



Yery similar results were obtained in a series of experi- 

 ments, executed at Ilohenheim,^' on the digestibility of 

 " flesh meal " by swine. It was fed in varying quanti- 

 ties along with potatoes. Assuming that the digestibility 

 of the potatoes was not altered by the addition 'of the 

 highly nitrogenous flesh meal, the following numbers were 

 obtained for the digestibility of the latter :
