Vol. XII. No. a 



tion was due both to a slight toxicity of the extracted kernels and to the 

 restricted diet. This condition was remedied, as previously described. 

 The animal was continued on the outdoor turf lot for 35 days and then 

 removed to a small indoor pen, where for 70 days longer she gained 

 steadily. 



Throughout the experiment the daily feed was maintained at i per 

 cent (of body weight) of extracted kernels plus 3 per cent of corn supple- 

 ment.

Two Other small pigs, No. 7 and 8, were also fed on this diet of ex- 

 tracted kernels and corn meal on the same basis as in the previous case. 

 On a few days it was necessary to use whole or cracked corn in place of 

 corn meal, owing to a lack of meal. The results in general were the same. 

 There was fair growth, but after six or eight weeks the pigs lost their 

 keen appetites and developed a tendency to squat on their hindquarters 

 and to walk stiffly. The growth curves in figure 3 show the general 

 results. The gain was fair, 0.581 pound per day for the female and 

 0.556 pound for the male pig. The experiment was discontinued on 

 the eighty-eighth day.
