THE DANISH EXPERIMENTS 



Elaborate swine feeding experiments involving nu- 

 merous problems have been conducted by the Danish 

 experiment station at Copenhagen. These experiments 

 were extensive and on the co-operative plan ; the animals 

 were kept upon estates and fed in the ordinary way by 

 farmers, but the tests were arranged and results observed 

 by officials of the experiment station. The large num- 

 ber of hogs, in some series practically a thousand, gave 

 a certainty to the averages which made the experiments 

 of unusual value. The author of "Feeds and Feeding" 

 painstakingly worked over the 39 periodical reports on 

 the Danish experiments which had been issued prior to 

 the publication of his work, and one of its chapters is 

 devoted to results obtained by the Copenhagen station. 

 In referring to the extensive Danish trials in root feed- 

 ing, Professor Henry has said : 



"In the Danish experiments such roots as mangels 

 and other beets, turnips and carrots, were usually fed 

 uncooked. In one series of experiments it was found 

 that from eight to ten pounds of mangels equaled one 

 pound of grain. The quality of pork from pigs given 

 mangels and other roots was satisfactory. Even when 

 one-fourth of the nutriment furnished consisted of roots 

 the pork was still of good quality. In one group of ex- 

 periments in which 204 pigs were used, four kinds of 

 roots were fed in addition to dairy refuse and grain. 

 The conclusions were tliat jYi pouiids of Eckendorf 

 mangels. 6^ pounds of Elvetham mangels, five pounds 

 of fodder beets and four pounds of sugar beets were
