figures, however, show that both lots throve on the rations 

 supplied to them, and the increase in live-weight in lot I. 

 would no doubt have been greater than it is, had it not been 

 that two of the cows, Nos. 85 and 93, were " off their food " 

 for some days during the period, when they both actually 

 lost weight. The two cows were not ailing at the same time, 

 and it should be stated that their condition did not, apparently, 

 affect the milk in any way. 



EXPERIMENT B. 



At the end of four weeks from the completion of Experi- 

 ment A just described, a second experiment was commenced 

 with the same cows. In this case they were out on grass, but 

 received an allowance of concentrated food in addition, the 

 two lots of cows being reversed as already explained, lot I. 

 receiving the heavier ration. 



Table VI. gives the yield of milk by the two lots for 12 

 weeks.
