average of the individual live weight had reached 185 lbs. Skim milk, 

 corn meal or corn and cob meal, wheat bran and gluten meal furnish- 

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

 the place of the clear corn meal on the eighth 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 experiment. 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 sup- 

 plied by a gradually increasing quantity of a mixture consisting of two 

 weight [)arts of gluten meal and one weight part of wheat I)ran. On the 

 3d of January, at the beginning of the third month, tlie daily diet was 

 changed ; the latter consisted hereafter of six quarts of skim milk and 

 a mixture pi-epared 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. 



The entire experiment was managed, as far as [)racticable, to serve 

 as a repetition of our seventh feeding experiment. The substitution 

 of the corn and cob meal of our own production from a superior home 

 raised corn, for the clear corn meal of our general market, may well be 

 considered of but little consequence. This view is fully supported 

 by a careful analysis of botii. The financial result of the eighth 

 experiment, like those of the seventh, are superior to those o!)tauied 

 in the pieceding five feeding experiments. This fact becomes still 

 more worthy of notice, when considering that the seventh experiment 

 was carried on during a warmer period of the year, and thus under 

 more favorable circumstances than the eighth experiment. Our late 

 results seem to confirm the conclusions arrived at in oui- [jrevious 

 experiments, namely : 



First — A gradual periodical change from a rich nitrogenous diet to 

 that of a wider ratio between the digestible uitrogeuious and non- 

 nitrogenous food constituents of the feed, is recommendable in the 

 interest of good economy. 



Second — Tlie feeding effect of one and the same diet changes with 

 the advancing growth of the animal on trial. 



Third — The power of assimilating food and of converting it into 

 live weight decreases with the progress in age. 



Fourth — It is not good economy to raise pigs for the meat market 

 to an exceptional high weight. To go beyond from 175 to 180 

 [)ounds is only advisable when exceptionally high market prices for 

 dressed pork can be secured. In addition to what has been said on 

 this particular point in previous communications, 1 insert here, in a 

 tabular form, the estimated cost of feed used for the production of 

 one pound of live weight during the succeeding stages of the growth 

 of the entire lot of pigs vhich served in the eightii experiment.
