SOME EXPERIMENTS IN PIG-FEEDING. 29 

sufficient number in each lot and by exercising due care at 
HemourermmrielG «selection. | | hey practice, of making 
preliminary tests of the character described is therefore 
commended by Professor Campbell to all engaged in experi- 
mental work in the feeding of animals; that such precaution- 
ary trials are necessary is, he thinks, amply proved by the 
merited scepticism with which reports on feeding experiments 
have been so often received by farmers. | 
The main experiment began on December igth last, when 
the pigs in each lot were fed on the following rations :—Lot 
I., two parts barley meal, two parts sharps, and one part 
gluten; Lot II., one part barley meal, and one part maize; 
Lot III., one part barley meal and one part sharps. In each 
of these three lots the ration was given with four times its 
weight of water. In the case of Lot IV. the ration was 
similar to that of Lot III., one part barley meal and one part 
Sharps, but it was given with only twice its weight of water 
so that while the food given to Lot III. was in the usual 
sloppy condition, that given to Lot IV. was of the consistency 
of oatmeal porridge. The pigs in each lot were given as much 
as they would eat. The experiment was continued for eight 
weeks, and the principal results are shown below :—

The effect of adding maize and sharps respectively to the 
ordinary ration of barley meal is shown by the results 
obtained with Lots II. and III. The pigs receiving sharps 
yielded a higher percentage of pork, and each pound of
