EXPERIMENT A, 1912. 
The ration at Station 3 in 1912 was 3 parts of corn meal and 2 
parts of low-grade wheat flour throughout the season, with 25 per 
cent of shorts added from August 21 to September 8 and with about 
6 per cent of mixed feed added during September and November. 
The shorts and mixed feed gave fair results in warm weather, but no 
advantage was found when feeding them in cool weather. The 
specially prepared mixed feeds used in September cost $2.70 per 100 
pounds and were too expensive, but a mixed feed used later in the 
season cost only $1.60 per 100 pounds, which compares favorably in 
price with the other feeds. However, it would probably be advisable 
to substitute shorts for mixed feeds, as the latter are more apt to be 
adulterated. Lot 2 was fed 10 per cent of meat in addition to the 
regular ration, while lot 45 was fed a specially prepared mixture 
to note the effect of these feeds on feather picking, but no consistent 
results were obtained in these experiments. This subject is dis- 
cussed in detail under the heading " Feather picking." 
Condensed buttermilk, diluted with water and mixed with grain — 
13.5 gallons to 100 pounds — was fed throughout the season. This 
proportion of condensed buttermilk, while increasing the cost of 
the feeding, gave profitable results, as the general conditions at this 
station were not conducive to good results in fattening. The pro- 
portion of condensed milk to grain was double that used in Experi- 
ment C. The broilers and roasters were separated at this station 
and fed for different lengths of time. The results secured during 
November were very poor, there being an increased cost of gain 
compared with 1911,
