Feeding experiments were begun to determine the food value of skim-milk as compared with corn meal, and the value of shelled corn as compared with corn meal. For this purpose six Poland-China barrows about 7 months old and varying in weight from 160 to 204 pounds were divided into three lots, so arranged that the variations in the lots were as small as possible, the greatest variation between any two lots being seventeen pounds. The lots were known as A, B, and C. For three weeks Lot A was fed as much shelled corn as it would eat. Lot B was fed like Lot A, except that the corn was made into a coarse meal; Lot C like Lot B, with the addition of a fixed ration of skim-milk, as large as experience showed they would drink without waste. All had water. I n order to determine that the result obtained by the addition of skim-milk was not due to individual differences in the pigs, at the end of three weeks, the skim-milk was given to Lot B instead of Lot C, the food of Lot A remaining the same, and the feeding was continued three weeks longer. THE VALUE OE SKIM-MILK. Lot B (see tables 2 and 3) ate in three weeks, 251 pounds of corn meal, equivalent to four and one-half bushels of shelled corn, or three-fourths of a bushel per pig a week and gained 60.5 pounds; or it required 4.15 pounds of corn meal to produce one pound of increase. Lot C consumed 243 pounds of corn meal and 414 pounds of skim-milk and gained 88.5 pounds. According to the amount required to produce a pound of increase in Lot B, 243 pounds of corn meal would produce 58.5 pounds of increase, leaving 30 pounds produced through the influence of the 414 pounds of skim-milk. It required, therefore,
