purpose, very often produces better results than whole 

 corn. If an excess of feed, especially of protein, is fed, 

 and the factor of waste is established, it is decidedly 

 harmful both to the pig and to the gains in live weight 

 that may be made. It seems to be a comparatively easy 

 matter to feed a pig to death on nitrogenous feeds. This 

 nutrient very often is found in feeds that are highly con- 

 centrated in this regard and also are very digestible, thus 

 enabling a pig easily to eat an excess. Furthermore, a 

 pig has the power to digest more of this nutrient than he 

 can assimilate. Consequently, if a pig is put on full feed 

 on nitrogenous concentrates, he may eat enough to kill, 

 or at least seriously to injure him. If he eats a little less, 

 or not enough to kill him, he may eat enough so that he 

 will become permanently stunted or runty. 



If nitrogenous concentrates are fed separately to a 

 bunch of pigs, those that get to the trough first, or those 

 that are largest and strongest and can crowd out the 

 smaller or weaker ones, are likely to eat too much. Cases 

 have come to notice where breeders thought they had hog 

 cholera in their herds when probably it was nothing but 

 over-feeding on protein in this form. It was noticed that 

 the largest and best pigs were the ones that would die. 

 This is true, because they are the ones that would eat the 

 largest quantity, hence get the greatest excess, which re- 

 sulted fatally. 



In order to overcome these difficulties, it is very essen- 

 tial that each pig in a bunch receive its proportionate 

 share of the ration, especially of the nitrogenous concen- 

 trates. For this reason it is advised that the feeds of a 

 ration be combined in such a manner that this difficulty 

 is reduced to a minimum. The nitrogenous concentr;ates 

 should be diluted with the carbonaceous concentrates as
