172 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



and fattening pigs. Without going into details, it may be 

 stated that an exclusive ration of beans is not regarded as 

 satisfactory. For growing pigs, a ration consisting of three 

 parts beans and four parts corn meal did not prove so satis- 

 factory as a mixture of two parts beans, two parts wheat 

 middlings, and three parts corn meal. The last-named mix- 

 ture gave an average daily gain per pig of about one and one- 

 third pounds per day, which is regarded as satisfactory. 



Three trials of beans compared with equal parts beans 

 and com meal were made with fattening hogs. The results 

 of the three trials are briefly summarized in the following

The addition of com meal increased the efficiency of the 

 ration about 3^/2 per cent. 



The relative cost of the two feeds and the cost of cooking 

 would have to be considered by the feeder in coming to a 

 decision regarding the economy of the rations. 



Wheat Middlings. — Wheat middlings, frequently called 

 " shorts," is one of the very best feeds for young pigs. It is 

 rich in bone- and muscle-forming constituents, and does not 

 tend to make growing pigs too fat. Its value as a supplement 

 to corn has already been noted, and it combines well with 

 almost any kind of meal. As a single feed for fattening, it 

 is not economical, but it is conducive to thrift and growth 

 when used as a part of a meal ration for fattening pigs. The
