THE CHESTER WHITE 501 



modern breeding has been toward refinement and smaller size, 

 so that the Chester White does not naturally develop excessive 

 size. Mature boars in fair flesh should weigh about 600 pounds 

 and sows 450, while barrows at six to eight months should feed 

 to weigh 350 pounds. 



The Chester White as a feeder ranks high. The barrow of this 

 breed will compare favorably with any breed in returning results 

 for grain fed. The writer has supervised the feeding of many 

 Chester Whites at the Indiana Experiment Station, when very 

 rapid and profitable fattening resulted, average gains of one pound

 made daily in feeding experiments of several months' duration. 

 In breed tests with pure-breds at various stations the Chester 

 White has made a good record. At the Vermont station in a 

 172 days' test Chester Whites made an average daily gain of 1.36 

 pounds, dressing out 84.5 per cent carcass. At the Maine station 

 a daily average of 1.15 pounds was secured for 140 days, and of 

 i .05 pounds for 117 days at the Ontario Agricultural College, 

 dressing out 77. 10 per cent carcass. In other experiments at the 

 Ontario Agricultural College Professor Day reports that it 

 required 3.37 pounds food for a pound of gain with Chester
