THE PIG 



required 357 pounds of feed for 100 pounds of gain with the 

 Poland-China, surpassing the Berkshire, Large Yorkshire, and 

 Duroc-Jersey. At the Iowa Experiment Station, in a breed trial 

 including sows and pigs before and after weaning, it cost ^3.15 

 per 100 pounds of gain before weaning and ^2.23 after wean- 

 ing with the Poland-China, materially surpassing the Berkshire, 

 Chester White, Duroc-Jersey, and Tamworth, being excelled by 

 the Yorkshire only. In feeding trials at the Ontario Agricultural 

 College the Poland-China made an average daily gain of .9 pound,

 the Illinois University. Photograph from Professor William Dietrich 



requiring 40 if pounds of grain for 100 pounds of gain. In the 

 Ontario trials the economy of gain by the Poland-China was 

 the poorest of any breed, which is rather an unusual result. The 

 following figures, published by Henry in Feeds and Feeding, 

 indicate the value of the Poland-China as a feeder.
