HATCH EXPERIMENT STATION. 



[Jan. 



Details of Experiment II. 



The object of this experiment was to compare the nutritive 

 effect of corn meal with oat feed. Six grade Chester AVhite 

 pigs, all from the same litter, were used. The pigs were 

 kept in the same pens and handled in the same way as de- 

 scribed in the previous experiment. They had been in the 

 pens over a month before the experiment began. 



Feeding. — The pigs were each fed at the beginning 5 

 quarts of milk together with 3 ounces of meal to each quart 

 of milk, and increased in this proportion till 8 quarts of 

 milk were fed ; the grains were then still further increased 

 from time to time to satisfy the appetites of the animals. 



Feeds. — The skim-milk and corn meal were of the same 

 average quality as reported in the previous experiment. Oat 

 feed is the refuse from factories engaged in the preparation 

 of oat meal for human consumption. It consists of the poor 

 oats, oat hulls and some of the bran and starch which are 

 removed in the process of manufacture. It is, as the corn 

 meal, a heat-producing rather than a flesh-forming feed. 

 Oat feed varies very much in composition, and consequently 

 in feeding value. The sample used may be considered an 

 average one.

The presence of the high })ercentage of fiber in the oat 

 feed is indicative of a considerable amount of hulls.
