PIG-FEEDING EXPERIMENT. 



On April 28, 1915, a pig-feeding experiment was commenced with 

 the object of determining the comparative feeding value of a ration 

 composed of native feed and that of a ration consisting of imported 

 feed. The eight pigs used in the experiment were of the Berkshire 

 native cross, six months of age, but somewhat undersized although 

 in a healthy condition. Six sows and 2 barrows were used, 3 sows 

 and 1 barrow being contained in each lot. (See PL V.) The ex- 

 periment was run for 64 days and each lot received 10 pounds of
