CHAPTER XXVII 

 FEEDING DAIRY CATTLE 



The most careful study has been given to the feeding of 

 dairy cattle. The experiment stations have done exten- 

 sive work in feeding, and many practical dairymen have 

 used feeding standards and made up carefully balanced 

 rations in efforts to work out their home problems. 



The feeding standards for dairy cattle cover young and 

 growing animals and those producing milk. There is not 

 much difference in the growth requirements of dairy and 

 beef cattle. Slightly more protein is recommended for the 

 latter, with about equal amounts of carbohydrates. The 

 amount of food given to milk-producing cows depends largely 

 on the yield of milk. The Wolf-Lehmann tables here quoted 

 are from Feeds and Feeding, by Henry and Morrison.
