pounds of dry grain or meal, a difference of 7 per cent, in favor 

 of using wet or soaked meal. 



The results show that the soaking of corn is about as useful in 

 increasing its feeding value as grinding. Experiment Stations 

 should give more data on both these important matters. 



838. Value of exercise.— At the Utah Station, ^ Mills gathered 

 data on this subject with pigs during trials lasting four years. 

 Some of the animals were confined in small pens, others in yards, 

 while still others had the run of pastures. The pigs used were the 

 common stock of the region, weighing about 75 pounds each when 

 the trials began. A summary of these trials is as follows: 

 Results of four years' trials with pigs confined in pens and allowed

 of gain. 



Pigs confined in small pens 90 lbs. 512 lbs. 



Pigs allowed exercise in yards and run of pastures. 1 . 10 lbs. 420 lbs. 



These figures show .2 of a pound greater daily gain, and a sav- 

 ing of 92 pounds of grain, or 18 per cent, of the feed, in making 

 100 pounds of gain, in favor of yard and pasture over close con- 

 finement. The reader should remember that the results were 

 obtained with shotes, and that the pastures should be credited 

 with the food they furnished, which is of course an unknown 

 amount. (903) 



839. Value of shelter.— At the Kansas Agricultural College, » 

 Shelton tested the value of shelter during winter with ten pure- 

 bred Berkshires, weighing from 200 to 250 pounds each, divided 

 into two lots of five each. One lot was placed in a warm base- 

 ment, each pig occupying a pen by itself. The pigs in the other 

 lot were likewise kept in separate pens, but in an open yard, the 

 only protection being a board fence on the north. The trial began 

 November 27, lasting ten weeks. The outdoor temperature ranged 

 from 12 degrees below to 31 above zero, Fahr., and the indoor tem- 

 perature from 19 to 42 degrees above. The pigs were given all the
