BULLETIN 21, U. S. DEPARTMENT OE AGRICULTURE. 



A ration composed of about 1 part of shorts, 2 of low-grade flour, 

 and 3 of corn meal was fed until August 12, when it was changed to 1 

 part of shorts, 1 of flour, and 2 of meal. On August 23 another change 

 was made to 1 of shorts, 2 of flour, and 4 of meal, which was again 

 changed on October 8 to 1 of shorts, 3 of flour, and 9 of meal, which 

 was fed to the end of the season. The gains and cost were quite con- 

 sistent, as the variation was due largely, if not entirely, to conditions 

 other than feed. Chickens will use a larger per cent of corn meal more 

 efficiently during cool weather, as the feeding season progresses. 

 These records show a marked decrease in gains during the hot weather 

 in August, and an extremely high cost of gains during November and 

 December. The poor results obtained hi August were due partly to 

 overcrowding and perhaps partly to feeding a mixture which was too 

 thick during the extremely hot weather.
