BULLOCK FEEDING EXPERIMENT. 199 

five pigs each, the difference in the total live weights of the 
two sets being only 4lbs. The experiment commenced on 
September rst and finished on November 21st, 1899. Both 
lots received the same amounts of separated milk and meal 
(principally maize-meal), but to Lot I. the separated milk was 
given sour, while Lot II. received sweet separated milk. The 
manner of housing and general treatment were as described 
in the preceding experiment. 
At the commencement of the experiment Lot I. weighed 
700 lbs., and Lot II. 704 lbs., whilst on November 21st they 
had increased to 1,407 lbs. and 1,422 lbs. respectively. 
Both lots of pigs were killed on the conclusion of the 
experiment and sold for 8s. 9d. per score of 20 lbs. The 
dressed weight of Lot I. was 1,020 lbs., which at 8s. 9d. pro- 
duced £22 6s. 3d.; Lot II. weighed exactly 20 lbs. more than 
Lot I., so that the cash difference in favour of Lot II. was 
8s. od. 
From this difference must be deducted ts. 9d., the estimated 
value of the 4 lbs. extra weight of Lot II. at the commence- 
ment of the trial. A balance of 7s. is thus left in favour of the 
use of sweet separated milk. The butcher's report was 
that both lots were of equally good quality. 
It would seem therefore from this experiment that the 
feeding value of separated milk is not increased by souring, 
but that, if anything, its feeding properties are slightly 
impaired. 

FEEDING EXPERIMENT WITH BULLOCKS. 
An experiment to compare the feeding values of maize 
meal and barley meal was carried out by the University 
College of North Wales, Bangor, during the months of 
January, February, and March, 1900. Two lots of Welsh 
bullocks, two-and-a-half years old (four in each lot), which 
had been grazed on the College farm during the previous 
summer, were selected for the purpose. ‘They were put in 
the stalls towards the end of December, and were similarly
