Calf Rearing Experiments. 



215 



weights and gains of the various lots during each of these 

 periods is shown in the table above. 



Some of the cattle were sold on February 17th and the rest 

 on March 17th, 1903, at an average price of 34s. per cwt. live 

 weight. They were not sold in a fat condition, but were sent 

 by the buyers to Scotland to be finished. Reckoned at this 

 price per cwt. on the average live weight on February 16th, 

 1903, the average value per head of the cattle in the various 

 lots was as follows : — Lot I., £13 12s. 6d. ; Lot II., £12 18s. ; 

 Lot III., £\2 14s. ; and Lot IV., £12 17s.

At the end of the experiment Lot I. were therefore worth 

 from 1 8s. 6d. to 14s. 6d. more per head than the cattle reared 

 on separated milk and a cream substitute. This superiority in 

 value bears, however, no proportion to the extra cost incurred 

 in rearing Lot I., as shown above. 



As already stated, the tests described above refer to the 

 calves which were not weaned until the end of the twentieth 

 week ; but some of the oldest calves in each lot began to be 

 weaned after August 7th, 1901, and these formed the subject 

 of the second experiment. Up to this time the feeding of 

 these calves was exactly the same as for those in the corre- 

 sponding batches of the experiment recorded above. 



There were four calves in each of the first three lots, and
