THE DIGESTIBILITY OF CATTLE FOODS. 



Ill 



Cottonseed Feed Meal, Crcaino Brand. 

 This product consists of a mixture of high-grade cottonseed 

 meal and cottonseed hull bran, the latter being the cottonseed 

 hull from which the lint has been removed. 



Summary of Coefficients, Cottonseed Feed Meal, Creamo Brand, Series 



XVII., Period III. 



The digestion coefhcients in this experiment agreed closely 

 except for fiber. The fiber coefficient was, however, low in 

 both instances, as was to be expected because of the tough, 

 woody character of the hull. This material contains only about 

 three-fourths of the total digestible dry matter of cottonseed 

 meal of good quality. Furthermore, since it contains much less 

 digestible protein, and two and one-half times as much total 

 fiber as genuine cottonseed meal, it is not worth more than one- 

 half as much for animal feeding. In fact, the northern farmer 

 cannot afford to purchase it at present prices in place of the 

 genuine article. 



Wheat Screenings. 

 Wheat screenings consist of the light wheat seed, weed seeds, 

 chaflF and dirt separated from the grain as it comes to the mill 

 in preparing the wheat for the manufacture of flour. Their 

 composition depends upon the kind of seeds predominating and 

 upon the amount of dirt and chaflf present. They necessarily 

 vary so much in composition that no general statement as to 

 their nutritive value can be made, and the figures reported 

 below should not be understood as applying to all wheat screen-
