These experiments in connection with those previously made 

 show that the rations containing less than half the concentrates 

 in the form of oil cake were nearly as effective as a pure grain 

 ration, and that increasing the quantity of oil cake fed produced 

 poorer results, the difference being greater when skim milk was 

 fed than when feeding whey. When roots were fed in both 

 rations the effect of the oil cake was stUl not so good, so far as 

 gain in live weight goes, as in case of pure grain feeding. These 

 results are of pectdiar interest, since the higher protein content of 

 the oU cakes would a priori indicate a higher feeding value for 

 them than 13ie cereals possess. In feeding trials with cows at the 

 same Station (647) and elsewhere, oU cake has always been 

 found superior to grain in nutritive value. They show that oil 

 in feeds has not the high nutritive value with pigs assigned it by 

 trials with the ruminants. While we accept these results and 

 should act upon them in the practical feeding of the pig, we 

 await the studies of the investigators to show why oil in feeds is 

 less valuable with this animal than with the cow.
