SUPPLEMENTARY FEEDS 59 



some nitrogenous feed either concentrate or roughage. 

 Cottonseed meal, ground linseed cake or oil meal, and 

 gluten meal are among the most common nitrogenous 

 concentrates, while alfalfa, clover, and cow-pea. hay are 

 nitrogenous roughages. Whether or not it will pay to 

 buy nitrogenous concentrates where good clover or 

 alfalfa hay is available depends upon the age of the cattle 

 to be fed, the price of corn, and the price of cotton seed 

 meal, oil meal, or some other available nitrogenous 

 concentrate. 



AN ILLINOIS FEEDING EXPERIMENT 

 During the winter season of 1903-1904 the Illinois 

 Experiment Station fed one carload of two-year-old 

 choice feeding cattle on broken ear corn and clover 

 hay and another carload of cattle of the same age and 

 grade on broken ear corn, clover hay, gluten meal, and 

 oil meal (pea size ground linseed cake). These cattle 

 were fed for a six-months' feeding period and were well 

 finished at time of sale. Feeds were charged at the 

 following prices: Per ton 



Ear corn, 35c. per bushel, broken ear corn $10.20 



Oil meal (ground linseed cake, pea size) 24.00 



Gluten meal 29.00 



Clover hay 8.00 



With a ration of broken ear corn and clover hay re- 

 sults were as follows : 

 Average daily gain per steer in pounds (186 days) . . 2.08 



Pounds pork per steer made by hogs following 62.60 



Pounds gain on steers per bushel corn fed 6.69 



Pounds gain on steers and pigs per bushel corn fed . *7.98 



Net cost of 1 pound gain on steers $.059 



Cost per cwt. of feeders in feed lot $4.53 



Value per cwt. when marketed $5.95 



Net profit per steer, corn 35c, clover hay $8 per ton. 



Gains in pork credited at $5 per cwt 9.84 



Net profit per steer, corn 40c, clover hay $10 5.68 



*With each bushel of corn fed in this lot there was an ayerage of 

 approximately ten pounds of oil meal or gluten meal fed in addition 

 to the corn, which of course was not the case where corn was not 

 supplemented with a nitrogenous concentrate.
