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,

requiring 401! 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.
