Feeds and Feeding. 



B, getting less water. As the results are practically equal, it 

 cannot be said tliat the addition of water to the skim milk was a 

 disadvantage in these trials. 



905. Winter and summer feeding compared. — Pig-feeding ex- 

 periments conducted by the Copenhagen Station ^ since 1887 have 

 been sununarized with a view of obtaining information concern- 

 ing the amount of feed required for 100 pounds of growth in 

 winter and in summer. In all trials the skim milk, whey, roots, 

 etc., fed have been reduced to their grain equivalent as deter- 

 mined by the various trials. The animals were separated into 

 three groups, according to their live weight. The following 

 average results as to feed eaten for one hundred pounds of 

 increased live weight were obtained: 



Feed consumed for one hundred pounds increase with pigs in winter 

 and in summer — Copenhagen Station. 



The table gives the average results of 100 experiments in win- 

 ter and 99 in summer. Since each trial included from 20 to 30 

 animals, or more, we have the average results obtained with 

 feeding at least 2,500 animals. The feed for one pound of gain, 

 given in ''totals and averages," is the arithmetical mean of each 

 set of three figures in the different columns, the data for each 

 period of growth being considered of equal value without regard 

 to the number of experiments included in each, since all the 

 groups contain an ample number of experiments to give a true 

 expression of the feed requirements of the animals embraced 

 within each period.
