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.
