PREVIOUS EXPERIMENTS. 



During the winter of 1910-11 (November 17 to March 17) this 

 bureau, working in cooperation with the Alabama Experiment Sta- 

 tion, carried on an experiment in fattening calves on various rations. 

 These results are published in Bulletin 147 of the Bureau of Animal 

 Industry and in Bulletin 158 of the Alabama Experiment Station. 

 The first lot of calves was fattened on a ration of cottonseed meal, 

 hulls, and alfalfa hay. The second lot was given a one-third ration 

 of corn-and-cob meal in conjunction with the cottonseed meal, hulls, 

 and hay. The third lot was given a liberal allowance of corn-and-cob

 ration. As the work reported in the present bulletin is really a dupli- 



1 This work was done in cooperation with the Alabama Experiment Station, J. F. 

 Duggar, director, and the Mississippi Experiment Station, E. R. Lloyd, director. G. A. 

 Scott, of the Animal Husbandry Division, U. S. Department of Agriculture, assisted in 

 preparing computations.
