ANTINEURITIC VITAMIN IN THE FLESH OF HENS 
In Table III are shown the .results of feeding tests with the dried flesh of 
Rhode Island Red, Barred Plymouth Rock, and White Leghorn hens as the 
source of vitamin B in the rations. The percentages of dried flesh in the several 
rations ranged from 15 to 30. The results of these experiments show that the 
flesh of each of the three lots of hens had a very low antineuritic value. The 
pigeons in pen 20 which were fed a ration containing 15 per cent of Rhode Island 
Red hen flesh show the maximum survival period, 28 days, while those in pen 
18 which were fed a ration containing 20 per cent of Barred Plymouth Rock 
hen flesh show the minimum average survival period of 19 days. Not a pigeon 
survived the test period of 56 days, the maximum survival period for an indi¬ 
vidual bird being 37 days. All pigeons receiving the hen-flesh rations lost in 
weight, the individual losses ranging from 3.7 to 41.4 per cent, and the average 
pen losses from 15.1 to 28.1 per cent. 
On the whole, it appears that the flesh of the hens had an appreciably lower 
content of the anitneuritic vitamin than did that of the frying chickens. This 
difference is probably due to the fact that the young chickens were on free range 
and received a greater abundance of green feed than the hens which were con¬ 
fined in yards, although the latter received a certain amount of green feed.
