Eighth Feeding Experiment. 



Six animals of a mixed breed, weighing from twenty-three 

 to twent^'-nine pounds, served in the experiment. The 

 latter began Nov. 8, 1887, and lasted until March 12, 1888, 

 or 124 days ; the average of the individual live weight had 

 reached 185 pounds. Skim milk, corn meal or corn and 

 cob meal, wheat bran and gluten meal, furnished the fodder 

 ingredients of the daily diet. The corn and cob meal took 

 the place of the clear corn meal on the 8th of January. 

 The daily ration of skim milk reached, within the first week, 

 six quarts per head. This amount, being the limit of our 

 home supply, was fed daily until the close of the experi- 

 ment. Skim milk and corn meal, two ounces of the latter 

 to one quart of the former, constituted the diet for about 

 three weeks, when the steadily increasing demand for food 

 was supplied by a gradually increasing quantity of a mix- 

 ture consisting of two weight parts of gluten meal and one 

 weight part of wheat bran. On the 3d of January, at the 

 beginning of the third month, the daily diet was changed ; 

 the latter consisted thereafter of six quarts of skim milk 

 and a mixture prepared of four weight parts of corn and cob 

 meal, one weight part of wheat bran, and one weight part 

 of gluten meal. The quantity required of the latter to meet 

 the daily wants of the animals began with forty-eight ounces 

 per head, and rose gradually to seventy-two ounces. (See, 

 for details, subsequent tabular statement.)
