Calf Rearing Experiments. 



211 



each lot, and these ceased to receive milk after twelve weeks of 

 experimental feeding. The majority, however, were not weaned 

 until the end of the twentieth week of the experiment, and as 

 this longer period constitutes a fairer test of the influence of the 

 rearing rations, the results obtained from these calves are more 

 reliable and are here considered apart from the results obtained 

 in respect of the calves which received milk for only twelve 

 weeks. 



The calves under experiment were of the cross-bred short- 

 horn type. From May 27th, 1901, until June 12th, 1901, when 

 the calves were weighed for the first time, the rations of the 

 various batches were gradually changed to those which they 

 were to receive during the course of the experiment. The 

 rations fed to each lot of calves during the summer of 1901 and 

 up to the time weaning was completed are shown in the table 

 below. The last two columns deal with the actual weaning 

 period.
