SKIM-MILK. 125 



is not the most' economical when cost of prod- 

 uct is considered, and that one pound to one 

 pound and a half of milk to one pound of corn- 

 meal is as much as can be profitably fed when 

 milk is valued at 20 to 25 cents per 100 ll)s. and 

 corn-meal at 75 cents per 100 lbs." 



Old and young animals. — The Wisconsin re- 

 port of 1889, page 24, gives some results of work 

 done to show the value of skim-milk fed to 

 mature versus growing hogs. 



With lot 1, hogs weighing 400 lbs., it required 

 1,430 lbs. of skim-milk and 301 lbs. of corn-meal 

 to produce 100 lbs. increase. Crediting the in- 

 crease at 4 cents per pound and charging 80 

 cents per 100 lbs. for the corn-meal, we have 11 

 cents per 100 lbs. left for the skim-milk fed. 



With lot 2, hogs weighing 144 lbs., it required 

 1,024 lbs. of skim-milk and 174 of corn-meal 

 to produce 100 lbs. live weight. Figuring this 

 on the same basis as lot 1, we secure 25 cents 

 per 100 lbs. for the skirh-milk. 



These figures illustrate the facts so often 

 brought out, that to do profitable work we 

 must have young and growing animals. 



Before and after weaning. — In the 1889 

 Wisconsin report is recorded some very valu- 

 able work in feeding pigs before and after 

 weaning. In these trials there were four lots 

 of pigs. The experiment made before weaning 

 continued from 55 to 64 days, the sows being
