after weaning, required almost identical quantities of milk and meal 

 for the production of 100 Ib. net gain. The foodstuffs used were 

 maize meal, middlings, oats, barley, and skim milk, weaning taking 

 place when the young pigs were ten weeks old, and feeding being 

 continued for a further seven weeks. The average of twelve litters 

 showed that for TOO Ib. gain" the sow and pigs before weaning re- 

 quired 231 Ib. of meal and 534 Ib. of skim milk, while after wea- 

 ning the young pigs (eight litters) needed 230 Ib. of meal and 

 539 Ib. of skim milk. 



Henry showed at the Wisconsin Experiment Station that the 

 weight at birth of a large number of young pigs averaged 2.5 Ib., 

 the heaviest pig weighing 3.6 Ib. and the lightest 1.6 Ib. By 

 weighing the young pigs regularly for seventeen weeks it was 

 found that they gained in weight on the average 1.9 Ib. in the 

 first week, 3.1 Ib. in the fifth week, 4 Ib. in the seventh, 5.4 Ib. 

 in the tenth, 5.9 Ib. in the fourteenth, and 7.6 in the seventeenth 

 week. The average gain for the last seven weeks amounted to 

 6 Ib. per week per pig, and at the end of the seventeenth week 

 the pigs were gaining over i Ib. each per day. This will be clear 

 from the following table: "
