EXERCISE 51. FORMULATING RATIONS FOR DAIRY Cows 1 



1. Make up a ration from the following feeds for a dairy cow weighing 

 1150 pounds and yielding 25.4 pounds milk a day: 



Corn silage, mixed clover and timothy hay, gluten feed and wheat bran. 



Compare with feeding standards and calculate cost per day at current 

 market prices and feed cost per 100 pounds of milk and per pound of butter fat, 

 assuming the fat content of the milk to be 3. 8 per cent. 



2. Make up a ration from the following feeds for a dairy cow weighing 

 925 pounds and yielding 16.3 pounds milk (4.9 per cent fat) : 



Clover hay (limited supply), corn silage, corn meal, wheat middlings and 

 linseed meal (O. P.). Calculate cost of ration and average cost of milk and 

 butter fat as under No. 1. 



1 Study carefully points to be considered in formulating rations, in Productive Feeding, 

 close of Chapter VIII, before writing this and similar exercises given in the Manual. In 

 this and the following ration exercises draw forms similar to that used in Exercise 50.
