Fourth Feeding Expeeimsnt (C, D). 



Five animals served in the experiment ; their live weights 

 varied from 30 to 38 pounds when entering upon the trial ; 

 they were of a similar mixed breed as those selected for the 

 third experiment. The daily diet of the entire lot consisted, 

 from December 8 to February 15, of four quarts of skim- 

 milk and eight ounces of corn meal, besides a mixture con- 

 sisting of two weight parts of gluten meal and one weight 

 part of wheat bran ; the increase demand for feed was sup- 

 plied by this mixture, which was moistened with water 

 before being fed. The daily quantity needed per head 

 amounted in the beginning of the trial to three ounces and 

 rose towards the close of that period to 12 ounces. Subse- 

 quently — until the 11th of May — another mixture, consist- 

 ing of equal weights of corn meal, gluten meal and wheat 

 bran, was substituted in its place. After May 11 until 

 the close of the experiment, May 31, a larger proportion 

 of corn meal was fed. The daily diet consisted, during that 

 period, of four quarts of skim-milk and a mixture of dry 

 feed, consisting of seven parts of corn meal, one part of 

 gluten meal and one part of wheat bran. On the 12th of 

 May the daily diet consisted, on* an average per head, of 

 four quarts of skim-milk, twenty-eight ounces of corn meal, 

 four ounces of gluten meal and four ounces of wheat In-an.
