diet, gives unsatisfactory results with fattening swine. 



The work for the past year was conducted in three series. 



First Feeding Trial of the Year. 



This consisted of twenty-four pigs, farrowed in July, Au- 

 gust, and September, 1905, and averaging 68 pounds in weight 

 when the trial began.. Previous to the trial, these pigs were 

 fed on skim milk, middlings, and a little corn. They were 

 divided into two lots, as nearly equal as possible in regard to 

 breed, age, weight, and condition. 



Lot I contained six pure-bred Poland Chinas, five pure-bred 

 Berkshires, and one cross-bred Poland-China-Berkshire. Seven 

 were barrows and five sows. 



Lot II consisted of six Poland-Chinas, four Berkshires, and 

 two cross-bred Poland-China-Berkshires. Nine were barrows 

 and three were sows. 



All lots were kept in pens, 10 feet by 12 feet in area, open- 

 ing into small yards on the south, which were protected by the 

 surrounding buildings. The pigs were fed in adjoining pens 

 constructed for feeding purposes, and used only at meal times. 

 The sleeping pens were kept well cleaned and well bedded 

 Both lots of pigs had free access to charcoal, wood ashes, and 

 salt. 



The experiment began January 20, 1906. Lot I was fed 

 shelled corn and heavy wheat middlings, equal parts by weight, 

 with two pounds of skim milk daily per head. The shelled 

 corn was fed first, and after it was consumed, the mixed mid- 

 dlings and skim milk were fed as a slop. Lot II was fed the 

 same ration, except that corn meal, made from the same lot 

 of corn was fed Lot I, was substituted for the shelled corn. 

 The corn meal, wheat middlings, and skim milk were mixed 

 together and fed as a slop. The water added m making the 

 slop was slightly warmed. Each lot had its ration weighed 

 out twice daily, and was given what it would eat. The corn 

 used in these trials was a yellow dent, grown near Madison in 

 1905. The following analysis of this corn was made by the
