Judging from the composition of sow's milk as shown by these 

 analyses, where cow's milk is fed to very young pigs some sugar 

 and cream should be added to make it resemble the milk they 

 would normally receive. 



829. Individual gain of young pigs. Since the student may wish 

 to know the individual gains of the members of the litter when 

 quite young, the following table is given showing weight and 

 gains of sow and pigs studied by the writer at the Wisconsin Sta- 

 tion. 1 The data cover 70 days before and 49 after weaning. 



Before the pigs were weaned the sow consumed 463 pounds of 

 corn meal and 1,207 pounds of skim milk. The pigs, fed at a 

 separate trough, during the same time consumed 122 pounds of 

 corn meal and 367 pounds of skim milk. During forty -nine days 

 immediately after weaning, the pigs consumed 651 pounds of corn 

 meal and 1,953 pounds of skim milk.
