EXERCISE 55. FORMULATING RATIONS FOR DAIRY Cows 



1. A cow consumed the following amounts of feed during one year: 1000 

 pounds of mixed hay, 100 pounds alfalfa hay, 6000 pounds corn silage, 600 

 pounds of soiling crops (green sorghum), 600 pounds each of wheat bran and 

 corn meal, 80 pounds of linseed meal, and 365 pounds distillers' grains. She 

 was on limited pasture 150 days. Her production for the year was 7 180 pounds 

 milk and 306 pounds butter fat; average body weight 1040 pounds. 



Calculate total feed units eaten, estimating one pasture day equal to 8 

 feed units; also average feed units per day, feed units per 100 pounds milk 

 and per pound butter fat. 



Calculate cost of ration at average local feed prices; also feed cost per 

 100 pounds milk and per pound butter fat.
