These results indicate a tendency toward a poorer utilization of 

 the feed in the heavier feeding, tho the difference is not great. 



827. Winter v. summer feeding.— While there are no available 

 data on the comparative economy of summer and winter swine feed- 

 ing for America, the Copenhagen (Denmark) Station^ records 199 

 trials with about 2,500 summer- and winter-fed pigs. In these 

 Danish trials all the skim milk, whey, roots, etc., fed have been re- 

 duced to their grain equivalent to facilitate the comparison. 



Feed required to fatten Danish pigs in winter and in summer. 



♦Danish pound=l.l avoirdupois lbs. 



It is shown that winter-fed pigs required 444 lbs. feed for 100 

 lbs. gain, or 11 per ct. more than summer-fed pigs. In Denmark 

 the summers are cool, and the winters more or less damp but not 

 excessively cold. It is fair to hold that in the northern parts of 

 America the difference between winter and summer feeding is some- 

 what greater than the Danish figures indicate, while over the greater 

 part of our country there is no greater difference and often no dif- 

 ference at all. (503) 



828. Wintering pigs in single-board cabins. — At the Ottawa Sta- 

 tion^ Grisdale kept lots, each of from 4 to 7 pigs weighing about 

 70 lbs. per head, during 60 days in winter in small board houses,
