mentioned on page 507. The increments allotted for work must be 

 large when the work is heavy. 



Although it would be more accurate perhaps to report energy allow- 

 ances for domestic animals in terms of the available food energy, in- 

 dividual and species variations and specific dietary effects make this 

 difficult. As a practical compromise, it is customary to use digestible 

 niurients as the index of energy content and to set daily allowances 

 in these terms. Recommended levels of digestible nutrients are listed 

 in the Appendix for beef and dairy cattle, sheep, horses, and swine. 

 Tables of the digestible nutrients of various stock feeds are also in- 

 cluded.
