younger the pig the greater the value derived from feeding 

 middlings. 



Wheat Bran. Bran is too bulky and fibrous to constitute 

 a large part of a pig's ration, but is useful for mature animals, 

 such as stock boars and breeding sows, or where it is desired 

 to give bulk to a ration that is considered too heavy in char- 

 acter. As a rule, however, middlings can be used to better 

 advantage than bran for the purposes mentioned. 



Flour. Various brands of low-grade flour are occasionally 

 put upon the market. Low-grade flour has a higher feeding 

 value than middlings, but is entirely unsuitable for feeding 

 alone, owing to its pasty nature. The writer's experience is 

 that it will cause digestive derangement when fed alone, and 

 must be diluted to a large extent with other feeds. Bulletin 

 167 of the Virginia Experiment Station reports better results 

 from soaking low-grade flour than from feeding it freshly 

 mixed with water. 



Hominy Feed. Purdue Experiment Station reports three 

 tests, with hominy feed and shorts compared with corn meal 

 and shorts. The meal was mixed in the proportion of two 

 parts of hominy feed or corn to one part of 'shorts. " Hominy 

 feed or chop consists of bran coating, germ, and part of the 

 starch portions of the corn kernel secured as a by-product in 

 the manufacture of hominy." According to analyses made at 

 Purdue, hominy feed contains about the same per cent of 

 protein as corn, but a higher per cent of fat and a slightly 

 lower per cent of carbohydrates. 



The average of three trials shows the following result: 



Hominy feed. Corn meal.
