Danish Pig-feeding Experiments.

into 77 lots, each containing at least 5 pigs. The experiments 

 lasted from 65 to 140 days, averaging 110 days. Sunflower-seed 

 cake, hemp -seed cake, palm- nut meal, peanut meal and blood 

 bread were each fed against rye or barley. The oil cake was fed 

 in connection with skim milk in some of the experiments, and with 

 whey in others. The lots fed grain and oil cake received half 

 their concentrates in the form of oil cake; those fed grain only, 

 received skim milk or whey in addition. The averages of these 

 extensive trials in which whey or barley meal was fed in oppo- 

 sition to oil cakes are shown in the following table, which con- 

 denses the results so that they may be easily compared by the 

 student:

These results prove conclusively, it would seem, that a pound 

 of oil cake has no more value for pigs than a pound of rye or 

 barley, no matter with what other substance or under what con- 

 ditions it may be fed. (206)

 Sunflower-seed cake and hemp-seed cake fed in connection with 

 skiin milk produced a soft quality of pork, which would com- 

 mand a lower price in the general market than that produced by
