Feeding Experiments with Dairy Cows^ 



By J. F. DuGGAR and R. W. Clark. 



Summary. 



With cotton seed at |8 per ton, cotton seed meal at 

 |20, cotton seed hulls at 14, and sorghum hay at |6.67, 

 butter was produced at a loAver cost per pound on a 

 ration consisting chiefly of raAV cotton seed and hay 

 than on one made up principally of cotton seed meal; 

 and hulls. 



The cows did not greatly relish cotton seed and hence 

 ate less than was desirable of the ration containing this ;. 

 hence on the larger amounts eaten the oil mill ration- 

 afforded a larger daily yield of both milk and butter 

 than did the farm-grown ration. 



In two experiments the average daily amount of milk 

 per cow was 17.5 pounds from the cotton seed ration and. 

 24.3 pounds from the cotton seed meal ration ; the dailT 

 production of butter per cow averaged .93 of a pound 

 with the cotton seed and 1.19 with the oil mill ration,, 

 this being an increase of 38 per cent in milk, and 28 perr 

 cent in butter. ^Nevertheless the low^ cost of the cot tort' 

 seed ration made it the more economical, the average 

 cost of the food required to make a pound of butter being: 

 only 10.1 cents when this ration was given and 15.3 cents^ 

 when the hulls and meal ration was employed. 



On account of the larger amounts of food consumed,, 

 the cows while receiving the cotton seed meal ration, 

 gained nearly half a pound a day in weight, while the 

 cows eating cotton seed in smaller amounts lost .8 of a 

 pound per day.
