EXERCISE 50. A STUDY OF RATIONS FOR DAIRY Cows 



A herd of milch cows, weighing on the average about 1100 pounds, are 

 each fed 10 pounds corn stover, 24 pounds corn silage, and 4 pounds corn meal 

 per head daily, yielding on this feed with blue-grass pasture in summer, an 

 average of 175 pounds of butter fat for the year. Suggest a change in the 

 system of feeding which will bring the ration closer to the standard and 

 increase the production of the cows. Calculate the cost per 100 pounds of 

 milk and one pound butter fat, assuming that the herd milk tested 4.2 per cent 

 for fat. 



Discuss variation from standard, and suggest further improvement in 

 the composition of the ration.
