VITAMIN B IN EDIBLE TISSUES OF OX, SHEEP, AND HOG. 40 
Til. EFFECT OF HEATING UPON THE ANTINEURITIC PROPERTIES OF OX LIVER, HEART, AND 
KIDNEY. 
The results of the tests which have been reported in this bulletin 
are summarized in Table 29. The data indicate that ox liver, 
heart, and kidney suffered material reduction in their antineuritic 
properties on cooking, the extent of the damage depending upon 
the temperature and time of cooking. However, fried and baked 
ox liver and cooked ox heart and kidney still had very fair anti- 
neuritic values.

hog), fed with polished rice.

1 The term “‘test period” indicates the duration of a feeding test which includes a number of pens of pig- 
eons, and the term is not synonymous with “survival period” which has already been defined. The sur- 
vival period ofa pigeon must be considered in relation to the length of the test period as well as to the change 
in weight of the bird in order to appraise the antineuritic value of the ration fed. In the earlier work with 
animal tissues, test periods of different length were employed, but in recent work an eight-week test has 
been adopted as standard.
