16 Cattle Feeding Experiments. 



COST OF FOODS USED IN EXPERIMENT JI. 



, Shelled corn, 35 cents per bushel (62^ cents per hundred) . 



Corn-and-cob meal, 38 cents per bushel (68 cents per hun- 

 dred). 



Wheat bran, f 15.00 per ton. 



Oil-meal, f 32.00 per ton. 



Cottonseed-meal, |32.00 per ton. 



Alfalfa hay, $6.00 per ton. 



Prairie hay, $6.00 per ton. 



The pork produced as a by-product was figured at market 

 price, viz., $5.75 per hundred. 



COMMENTS ON THE RESULTS. 



The table shows that shelled corn, oil-meal and prairie 

 hay gave the largest gains and that shelled corn, alfalfa, and 

 prairie hay gave cheapest gains. In this experiment the lat- 

 ter ration gave as large gains as were made on corn and cot- 

 tonseed-meal with prairie hay. 



Here again, as in three preceding experiments, corn and 

 prairie hay gave the smallest and most expensive gains. A 

 much larger amount of grain per pound of gain was con- 

 sumed by the steers of this lot, which explains in part at 

 least why more pork was produced for each pound of gain 

 made by those steers. 



The figures show that the use of oil-meal with corn and 

 prairie hay effected a saving of 35 per cent of the grain con- 

 sumed for one pound of gain made on corn and prairie hay 

 without oil-meal. The saving was 14 per cent by the use of 

 bran, 29 per cent with cottonseed-meal and 33 per cent with 

 alfalfa hay. 



Giving full credit for all pork produced, the net cost of 

 producing gains was 4.4 per cent less by the use of bran than 

 with corn alone, 19 per cent less with oil-meal, 8.9 per cent 

 less with cottonseed-meal, and 27 per cent less with alfalfa 

 hay.
