Feeds and Feeding. 



Feed was supplied to each animal separately, and a record kept 

 of everything consumed except the pasture grass. The weight 

 and gain of the pigs during the trial of 224 days are given in the 

 table: 



Weight and gain of pure-bred Berkshire and Poland- China pigs 

 Wisconsin Station. 



As these pigs were to be used for breeding purposes they were 

 supplied with a variety of nutritious foods, shorts, corn meal, 

 oil meal, with some milk and whey, the purpose being to secure 

 good bone and muscle rather than fat. In calculating results five 

 pounds of skim milk and ten pounds of whey were counted equal 

 to one pound of grain. The total gain and the feed required for 

 100 pounds of gain are as follows: 



Poland-Chinas. Berkshires. 



Total gain of lot l,1681bs. l,167lbs. 



Feed for 100 pounds of gain 524 Ibs. 512 Ibs. 



It will be seen that the Poland -Chinas gained one pound more 

 than the Berkshires, and required 12 pounds more grain for 100 

 pounds of gain. At the close of the trial the Berkshire sows, 

 ranging between 305 and 342 pounds in weight, were practically 

 mature in bone and muscle and carried considerable fat. The 

 Poland- China sows ranged from 333 to 366 pounds and were not 

 fully developed, being of a larger type than the Berkshires. To 

 have fed them to the same degree of maturity as the Berkshires 

 would have necessitated a farther gain in weight of from 25 to 50 

 pounds each. Having carefully watched the animals throughout
