Cattle Feeding Expcr.ment. 15 



(2) By feeding alfalfa hay, which is a protein-rich rough- 

 ness extremely palatable and readily masticated, in place of 

 prairie hay with corn alone, 14 per cent less grain was "re- 

 quired for each pound of gain on two-year-olds and 27 

 per cent less on yearlings. 



(3) Alfalfa hay, fed once per day in connection with corn 

 and well-cured cornstalks, furnished sufficient protein for 

 two-year-olds to make the three foods a combination pro- 

 ducing heavy and very economical gains more economical 

 than any other ration in the experiment. 



. (4) Corn and oil-meal mixed at the rate of one pound of 

 oil-meal to nine of corn, fed with cured cornstalks for rough- 

 age, made an efficient combination for yearlings, and one 

 quite as economical a,s corn and alfalfa, oil-meal at that time 

 being worth $25 per ton. 



(5) Sorghum hay fed with corn 90 per cent and oil-meal 

 10 per cent, the latter to supply needed protein, made a good 

 fattening ration for both two-year-olds and yearlings, though, 

 less economical than cornstalks, the latter being cheaper 

 because a by-product in corn production. 



(6) Though less profitable in the end, the cost of produ- 

 cing one pound of gain on two-year-olds was approximately 

 the same without the use of oil-meal as when the oil-meal 

 formed 10 per cent of the grain ration in connection with 

 corn and prairie hay and cost $28 per ton. On yearlings the 

 cost of producing one pound of gain was 17 per cent less with 

 10 per cent of oil-meal than without oil-meal when the latter 

 was worth $25 per ton. 



(7) The use of cornstalks, worth $2.50 per ton, in Lot 4, 

 as a substitute for one-half the alfalfa, worth $6 per ton, as 

 fed in Lot 3, reduced the cost of gains on two-year-olds 6 per 

 cent. 



(8) Thin two-year-olds from the 'range made practically 

 as large gains for food consumed as did yearling steers in 

 good grass flesh at the beginning of the experiment.
