14 Cattle Feeding Experiments. 



EXPERIMENT II. 



PROTEIN CONCENTRATES VS. ALFALFA FOR SUPPLEMENTING CORN 

 AND PRAIRIE HAY. 



This experiment was undertaken for the purpose of secur- 

 ing data on the relative values of Avheat bran, oil-meal, and 

 cottonseed-meal as sources of protein, in contrast also with 

 alfalfa hay. The cattle used in Experiment I were redivided 

 to make all lots average even in condition. This was accom- 

 plished by distributing the thinner steers of Lots 1 and 4 of 

 the former experiment among all six lots of the present ex- 

 periment. A period of three weeks between the two experi- 

 ments was used to get the lots on the new experimental ra- 

 tions, during which time snapped corn was gradually changed 

 to shelled corn. At the end of this interim of three weeks, 

 the beginning of Experiment II, February 15, 190G, each 

 steer in the several lots was receiving 17 pounds of corn per 

 day. As this was to be a period of heavy grain feeding, it 

 was thought favorable for testing protein concentrates. 

 Each lot was given a gradual increase of grain, the increase 

 being made according to the appetites of the cattle receiving 

 the several rations, tho the bran lot was purposely fed a little 

 more total grain than the other lots because of the greater 

 bulk and correspondingly less corn in a ration one-fourth 

 bran. 



RATIONS FED. 



The steers in the several lots Avere given rations as follows : 



Lot 1, corn and prairie hay. 



Lot 2, corn 75 per cent, bran 25 per cent, and prairie hay. 



Lot 3, corn 90 per cent, oil-meal 10 per cent, and prairie 

 hay. 



Lot 4, corn 90 per cent, cottonseed-meal 10 per cent, and 

 prairie hay. 



Lot 5, corn, alfalfa 50 per cent, prairie hay 50 per cent. 



Lot C, corn-and-cob meal, alfalfa 50 per cent, prairie hay 

 50 per rent.
