was used up to that time. The supply of condensed buttermilk was 

 very limited, so that it was necessary to dilute it with a larger per cent 

 of water as the feeding season advanced. The amount of condensed 

 buttermilk fed per 100 pounds of grain was as follows: 10 gallons in 

 August, 7 gallons in September, 4.5 gallons in October, and 3.3 gallons 

 in November. The rather poor results secured at this station during 

 the last part of the season may have been partly due to this lack of 

 buttermilk, but the results were quite variable throughout the entire 

 season. 



The cost of feed was considerably higher in 1 912 than in 1911. The 

 broilers and roasters were not separated at this station during this 

 feeding season. The high cost of the gains during October on lots 

 fed from 11 to 15 days would indicate that the common practice of 

 dividing the lots into broilers and roasters about the 1st of October 

 and gradually reducing the length of the feeding period of the latter 

 was more profitable than to feed roasters for 14 days after the 1st of 

 October.
