DANISH PIG-FEEDING EXPERIMENTS. 



I. Trials with Various Feeds. 



884. The work of Fjord and Friis. Since the year 1880 a large 

 number of pig- feeding experiments have been conducted by the 

 Danish Experiment Station at Copenhagen, under the direction 

 of the late Professor J. N. Fjord and his successor, F. Friis. 

 These experiments are exceedingly valuable because of the vari- 

 ety of conditions under which they were conducted, the large 

 number of animals included, and the care bestowed on the details 

 of the work. 



The feeding was conducted on the co-operative plan on a num- 

 ber of Danish estates, or large farms, under the direct supervis- 

 ion of the officials of the Station, who planned the experiments, 

 made the weighings, sampled and analyzed the feeds and con- 

 ducted the slaughtering tests. In these trials the pigs were 

 divided into selected even lots composed of five to ten animals 

 each, the different lots being so fed as to express the comparative 

 value of the feeds under examination. In a majority of cases 

 the object in view was the relative feeding value of different 

 swine foods under good farm conditions. Incidentally a number 

 of other problems were included, such as the value of shel- 

 ter, the influence of water on fattening, breed experiments, ques- 

 tion of sex in fattening, influence of season on fattening, etc. 

 The results of these experiments have been published in the 

 periodical reports (Beretninger) of the Station, of which thirty- 

 nine have appeared to date. 



The Danish pound equals 1.1 pounds avoirdupois. As the 

 results stated are nearly always relative, they are given in Danish 

 pounds, as they appear in the original reports. Wherever avoir- 

 dupois pounds are given, it is so stated.
