EXERCISE 52. FORMULATING RATIONS FOR DAIRY Cows 



1. Formulate a ration for the dairy herd made up of home-grown feeds 

 only. Show how it may be modified by the purchase of a commercial feeding 

 stuff; (a) with regard to nutritive effect only, (b) with regard to both cost 

 and nutritive effect. 



2. Five tons of alfalfa hay and 4 tons beets (mangels) make a sufficient 

 amount of feed for a cow producing 300 pounds of butter fat in a year. Cal- 

 culate the average daily ration, and compare with the Wolff-Lehmann and 

 Armsby standards. Suggest a modification of the ration that you may con- 

 sider will tend to increase its efficiency.
