52 



cent, of the feeding value of wheat bran, one ton of this 

 hay being equal to 1720 pounds of wheat bran. 



When wheat bran w^as worth |20.00 per ton cowpea 

 hay was worth |17.20 and vetch hay |20.00. 



The monthly profits per cow were |4,65 on the vetch 

 ration and 14.35 on the cowpea ration. 



One of the Jersey cows used in this test produced 

 butter at a cost for food of onh^ 8 1-3 cents per pounJ, 

 when fed on the vetch ration. 



Kunning cowpea hay through a feed cutter did nofc 

 decrease the waste in feeding this food. 



Pour and a half per cent more butter was produced 

 with soybean hay than with cowpea hay, if we take ac- 

 count of the portion of each actually eaten; however a 

 larger proportion of the coarse stems of the soybean 

 hay was left uneaten. 



When corn hearts was substituted for wheat bran the 

 yield of butter was increased by 8 per cent. 



The following combinations of food stuffs made sat- 

 isfactory daily rations for Jersey cows weighing be- 

 tween 700 and 800 pounds and producing a little more 

 than a pound of butter per day: 



(a) 4 lbs. cotton seed. 



2 lbs. wheat bran. ' 



11.8 lbs. vetch ha v. 

 Total 17.8 lbs. 



(b) 6.5 lbs. cowpea hay. 



9.6 lbs. cotton seed hulls. 

 4.8 lbs, cotton seed. 

 2.4 lbs. cotton seed meal. 

 2.4 lbs. wheat bran. 

 Total 25.7 lbs. 



(c) 6.6 lbs. soybean hay. 



8.6 lbs. cotton seed hulls.
