MISCELLANEOUS INVESTIGATIONS 139 



will be dropped from the standard in the course of time. This 

 remark is based upon certain experimental work, but the work 

 is not sufficiently advanced to warrant a definite statement. 



In the second place, the 'standard is very complex, and 

 it would be difficult for the busy farmer to calculate rations and 

 follow the intricacies of the standard. On the other hand, 

 Professor Dietrich deserves great credit for the thoroughness 

 of his investigations, and the standard is especially valuable 

 on account of the light it throws upon the protein requirement 

 of young pigs. There is no doubt that many a promising 

 litter has been stunted through ignorance of this important 

 point. No doubt the standard will eventually be modified and 

 simplified until it is brought within the reach of the average 

 intelligent feeder. 



HOGS FOLLOWING STEEES. 



Many farmers who fatten steers regard the hog as a neces- 

 sary adjunct to the business if a profit is to be obtained. 

 The hogs work over the droppings of the steers and fatten 

 upon the undigested grain in the manure of the cattle. 



Illinois. — The number of hogs per steer, which can be 

 used to advantage, will vary with the character of the ration 

 fed the steers. H. W. Mumford, in Bulletin 103 of the Illinois 

 Experiment Station, states : " Where enough pigs are provided 

 to consume undigested feed in the droppings of steers, it re- 

 quires fully twice as many where com is fed whole as it does 

 where meal is fed to the steers." The same writer secured 

 gains on hogs following steers ranging from 111.5' pounds of 

 pork to 6.3 pounds of pork per steer, in a feeding period of 

 six months. The largest gain was made by hogs following 

 steers fed shelled corn, and the smallest by hogs following 

 . steers fed com meal and silage.
