XXXVII. FEEDING EXPERIMENTS WITH PIGS. 



It will now be interesting to examine any experi- 

 mental evidence there is available, with regard to the 

 suitability or value of various foods for fattening of 

 pigs for the production of bacon. 



(a) Liquids. 



Separated Milk v. Whey. Kellner gave the com- 

 parative values of these two foods as 8 to 6 i.e., the 

 value of the former was one and one-third times as 

 great as the latter. 



In the West of Scotland Agricultural College 

 experiments at Kilmarnock (1905-8), the relative 

 values came out as 8J to 6, which come very near 

 Kellner's figures. 



The Danish standard for these two liquids gives 

 separated milk double the value of whey for fattening 

 purposes (i.e. 6 Ibs. skim milk, or 12 Ibs. whey are equal 

 to i Ib. meal). This difference is most likely due to 

 the fact that in the Kilmarnock experiments skim 

 milk and whey were fed in approximately equal 

 quantities per head per day, whereas in Denmark 

 only half the quantity of skim milk is given as com- 

 pared with whey. Few pig-feeders would be able to 

 make an average daily allowance of 4 galls, separated 

 milk per head, as half of this is generally considered 

 liberal ; consequently the Danish figure had better be 

 adhered to in this case for skim milk, viz., that it is 

 double the value of whey. At the Central Experimental 

 Farm, Ottawa, 6 Ibs. separated milk was found to be 

 equivalent to I Ib. meal, which confirms the Danish 

 figure.
