The analyses given for the feces represent their composition when moist 
(Table X). Heifer 301, which consumed less hay and more water than 
did heifer 298, produced the feces with the higher moisture content. 
The bulk of the feces evidently depends to a large extent on the amount 
of water consumed.

Table XI again demonstrates the similarity between the powers of the 
two heifers for using roughage and also indicates that their powers of 
digestion are very nearly equal.

This shows that the nutrients in Sudan-grass hay are all fairly easily 
digested. The digestion coefficients range from 47.4 per cent in the case 
of the protein to 70.6 per cent for the crude fiber, while that for the total 
dry matter is 64.9 per cent.
