" In the flrsst period of the first experiment 5 parts of middlings were added to the 

 ration. 



It is concluded that the tests with soy-bean meal indicate that it is possible 

 to grow in Indiana a feed which is equal in value to linseed meal as a supple- 

 ment to corn for fattening growing hogs in a dry lot. Corn should be the basis 

 of all rations for fattening hogs, but a larger proportion may be used with 

 tankage than when linseed meal is used as a supplement. With tankage the 

 hogs consumed more feed, made a more rapid gain, and were better finished 

 than when linseed meal was used. Soy-bean meal proved to l)e a more efficient 

 supplement than linseed meal both as regards the rate and cost of gain. 



Hog feeding, W. J. Quick and A. P. Spencer (Virginia Sta. Bui. 116, pp. 

 3-14, figs. 2). — In 70-day tests with 4 lots of 5 Berkshire hogs, 5 months of age, 

 skim milk was compared with blood meal as a supplement to corn, and well- 

 seasoned, hard, and flinty corn was compared with new corn coming directly 

 from the shock. With a basal ration of skim milk and middlings, the lot receiv- 

 ing new corn made an average daily gain of 1.47 lbs. per day at a cost of 5.99 

 cts. per pound of gain, whereas the lot receiving old corn made an average 

 daily gain of 1.5 lbs. at a cost of 5.6 cts. per pound of gain. With blood meal 

 and middlings for a basal ration, the average daily gain of the lot receiving 

 new corn was 1.37 lbs. at a cost of 5.9 cts. per pound, whereas the lot receiving 

 old corn made a daily gain of 1.4 lbs., costing 5.7 cts. per pound of gain. Analy- 

 ses of the feeds are given. 



" The profit made during the entire experiment differs less than one dollar. 

 From this data we concluded that blood meal and skimmed milk have a similar 

 feeding value when fed on the basis of an equal number of pounds of protein, 

 and as supplements to either old or new corn."
