INTRODUCTION. 
Last year the first bulletin containing experiments on digestibility 
of cattle foods was issued. In it was recorded the work done to 
determine the digestibility of cotton-seed hulls alone, and of the 
same fed with cotton-seed meal in a ration. 
A statement of how a digestion experiment is made was included 
with that bulletin,* and need not be repeated here. 
This bulletin records another year’s progress in the work of deter¬ 
mining the true value of these distinctively Southern cattle foods, 
in order that they may be the better appreciated, and fed for more 
economical production, in a rational system, than is possible by hap¬ 
hazard methods without these determinations. 
The digestion work accomplished and here reported, together with 
deductions therefrom, includes determinations on— 
1. Pulled Fodder (corn leaves alone) with two animals. 
2. Crimson Clover Hay with two animals. 
3. Cowpea-vine Hay with two animals. 
4. Soja Bean Silage with two animals. 
5. Corn Silage with one animal. 
6. Corn Silage and Raw Cotton-seed with one animal, duplicated. 
7. Corn Silage and Roasted Cotton-seed with two animals. 
8. Corn Silage and Cotton-seed Meal (ratio 12 to 1) with two 
animals. 
9. Corn Silage and Cotton-seed Meal (ratio 8 to 1) with two 
animals. 
10. Cotton-seed Hulls alone with three animals. 
11. Cotton-seed Hulls and Cotton-seed Meal (ratio 7 to 1) with one 
animal. 
12. Cotton-seed Hulls and Cotton-seed Meal (ratio 6 to 1) with 
two animals. 
13. Cotton-seed Hulls and Cotton-seed Meal (ratio 4 to 1) with 
two animals.
