158 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



" Tankage ranked second to skim-milk, followed very 

 closely by middlings, soy-bean meal, and linseed meal as sup- 

 plements to corn meal.' 7 



" There was less cash outlay for tankage than for any other 

 commercial nitrogenous feed, and a greater proportion of corn 

 could be used with it." 



" The -value of skim-milk was found to be : 



26.5 cents per cwt. as compared with linseed meal at $1.50 per cwt. 



24. cents per cwt. as compared with soy-bean meal at $1.50 per cwt. 



22.9 cents per cwt. as compared with tankage at $2.00 per cwt. 



28. cents per cwt. as compared with middlings at 1.25 per cwt. 



" Skim-milk has proved to be the most efficient supplement 

 to shelled corn or corn meal used in the experimental feed 

 lots at the station for the past five years in fattening hogs." 



" Tankage has been the most efficient commercial feed 

 used as a supplement to corn in fattening hogs under market 

 conditions prevailing during the past five years." 



Shorts, Skim-Milk, Tankage, Ground Bone, Alfalfa 

 Pasture. The Nebraska Experiment Station conducted a 

 series of experiments with shorts, skim-milk, Swift's digester 

 tankage, and steamed ground bone. 



Following are the rations used: 



Corn meal alone. 



Corn meal 75 per cent, shorts 25 per cent. 



Corn meal 25 per cent, skim-milk 75 per cent. 



Corn meal 90 per cent, tankage 10 per cent. 



Corn meal 95 per cent, tankage 5 per cent. 



Corn meal 90 per cent, steamed ground bone 10 per cent. 



During part of the time the hogs were on alfalfa pasture, 

 so that it is possible to study the effect of alfalfa with corn. 

 The last experiment brings out the comparison very clearly, 

 as is shown in the following table:
