As cottonseed meal is chiefly used in this State to supplement 

 feeding stuffs poor in protein, this constituent is of the first 

 importance. The very low grade meal (D) carried about one- 

 half as much protein as the best grade. The uniform relation 

 between the protein content of the meal and that of woody fiber 

 is noteworthy ; as the crude fiber increases, the protein decreases. 



THE DIGESTIBILITY OE DIEFERENT GRADES OE COTTONSEED 



MEAL. 



The chemical analysis of a feeding stuff helps to an under- 

 standing of its food value, but the real value is more clearly 

 brought out by actual feeding trials. The four grades of meal 

 were fed to sheep and their differences in digestibility and feed- 

 ing values are shown in the tables which follow. 



The digestion coefficients obtained on the different grades of 

 cottonseed meal with sheep.
