Suggestions for Pig-Feeders. [Jan., 



Skim milk has also been compared with grain alone and 

 with a mixed ration of skim milk and grain, and three results 

 may be quoted * : —

None of the pigs getting milk only attained over 100 lb. in 

 weight, and milk alone is not suitable for pig feeding, but 

 the result is an emphatic demonstration of the superiority 

 and economy of grain and milk over grain alone. 



In 1904 experiments were made at the Central Experimental 

 Farm, Ottawa, f young pigs varying from 43 to 80 lb. in 

 weight being fed on a number of different rations. In each 

 case the best and most economical gains were made by the 

 lots in which skim milk formed part of the ration. The 

 chief results of the most economical lots may be given 

 thus : —
