Tlw foi-pg-oing tablo sIioavs tli;ii wlun (lio gluten meal, containing' 

 larger amounts of protein and tat, was fed there was an increase both 

 ill tlir prrrcntagr of total solids and fat and in the total amount of fat 

 ]»roduced duiiiig the period in the ease of every eow. While tlieie were 

 slight changes in the percentag<' of solids-not-fat, these changes seemed 

 to he independent of the food, for in the case of every cow except No. 

 ■>"» there was a steady increase in the percentage of scdids-not-fat from 

 the beginning to the close of the exjx'riment regardless of the clianges 

 made in the grain food. The proportion of the fat to the solids-not fat 

 Avas noticeably larger with gluten meal. This would seem to be a case 

 of a one-sided increase of the fat, such as has been previously noticed 

 in a few isolated cases only. The increase in the percentage of fat when 

 the cows were changed from the corn-and-cob meal to the gluten meal 

 amounted in some instances to O.Gl and 0.70 per cent; and when they 

 were changed trom gluten meal to corn-and-cob meal there was a 

 (le(*rease of from 0.54 to 0.82 per cent in the fat. The interest of the 

 subject renders additional data for a larger numl)er of animals very 

 desirable. 



(Jalf-feeding experiment, J. Wilson, C. P. Citrtiss, B. S. A., 

 1). A. Kent, B. S., and G. E. Patrick, M. S. (pp. 143-151).— A com- 

 ]>arison of whole milk and skim milk for young calves. Four calves, 

 two Shorthorns and two Holsteins, a bull and a heifer of each, were 

 used for the trial. They varied in age from 33 to 64 days, and were fed 

 from April 1 1^ June 30 — 91 days. ]i^ach day the milk from three cows 

 was divided into two erpial parts, one half being divided equally 

 between the two bulls, and the other half set for Iii hours ami then 

 skimmed, and the skim milk fed to the two heifers. An attempt was 

 made to make the skim-milk ration approximately equal to the whole- 

 milk ration by adding- 1.5 pounds of ground flaxseed per day to the skim 

 milk of each animal. All of the calves received grain (a mixture of equal 

 ]>arts of ground oats, ground barley, corn meal, and wheat bran) and 

 clover hay in addition to the milk. The amount of these was the same 

 for each calf, and was increased with the growth. The rations fed and 

 gains made during periods of 15 days, together with a summary for the 

 01 days- feeding, are tabulated. During the whole ex]»eriment the 

 gains on the whole-milk ration were. Shorthorn 178 pounds and Hol- 

 stein 234 pounds ; and on the skim-milk rati(»n. Shorthorn 155 pounds, 

 and Holstein 171 pounds. 



The best results as to gain came from the whole milk, but taking all things into- 

 lonsidfration we regard the outcome of the experiment as quite favorable to the 

 skim milk and flaxseed ration. If the calves were to be judged by their coudition 

 as to thrift and general appearance, omitting the test of the scales, the verdict 

 would be in favor of the skim milk and flaxseed. * «* ^^ Heredity may or may 

 lint have tigured in the results, but if it did it was agaiust the skim-uiilk ration. 

 Both skim-milk calves were iu better condition than either of the others. At the 

 <ud of the experiment the milk was taken away from all of the calves and they wen; 

 jiiit f»n pasture and equal grain rations. Here again the results were in fiivor of tliei 

 hkim-milk calves. » » »
