Danish Pig-feeding Experiments.

We note that the pigs ate only a little more feed in winter than 

 in summer, and that it required 44 pounds or 11 per cent, more 

 feed in winter than in summer to produce 100 pounds of gain. 

 The figures given doubtless express the feed requirements of pigs 

 under ordinary conditions in Denmark. The climate of Denmark 

 is tempered by cool summers and is not excessively cold in win- 

 ter. The average temperatures observed during the trials are 

 given in the following table, the figures being for the air, stable 

 and feed:

The table shows there was an average difference of only 20 or 

 25 degrees Fahr. between the summer and winter temperature 

 when the experiments were conducted. These differences show 

 a narrower range than prevails in most parts of the United States. 



906. Light versus heavy feeding. In two series of experiments 

 with 60 animals in all, l the influence of the intensity of feeding 

 on gain was made a special object of investigation. One experi- 

 ment lasted 120 days, the other 210 days. The feeds used were 

 barley, buttermilk, skim milk and whey.
