NUTRITION OF FARM ANIMALS 



Thus at a comparatively small additional expense we are 

 able to improve the ration materially by adding the lacking

 or shortening the feeding period. 



802. Computing a ration from given feeding stuffs. There 

 are available for a dairy herd field-cured corn forage (including 

 the ears), clover hay, corn meal, wheat bran and gluten feed. 

 Table VII shows that these feeding stuffs, if of good average 

 quality, will furnish in 100 pounds : 



The cows average 850 pounds per head and have produced in 

 previous years an average of 20 pounds of milk per day testing 

 4 per cent of fat. According to Table I, the maintenance 

 requirement of such animals per day and head would be 

 approximately : 



Digestible protein 0.43 pound 



Net energy 5.40 Therms
