Antineuritic Vitamin in Poultry Flesh and Eggs 
465 
From the data presented in Table I it will be noted that the average survival 
period of the pigeons in pens 1 and 2 receiving only autoclaved rice was 25 days, 
while the average survival period of the pigeons in pens 3 and 4 receiving rice 
supplemented with dried autoclaved beef, cod-liver oil or butterfat, and ash 
mixture was practically the same, or 26 \ days. The average loss in weight of 
the birds in pens 3 and 4 was somewhat less than that of the pigeons in pens 
1 and 2, being 16.4 per cent as compared with 22.6 per cent. The average 
survival period of all the pigeons in pens 1 to 4, inclusive, was 26 days, and 
the average loss in weight was 19.5 per cent, 
ANTINEURITIC VITAMIN IN THE FLESH OF FRYING CHICKENS' 
In Table II are presented the results of feeding tests with the dried flesh of 
frying chickens of three breeds, viz, Rhode Island Red, Barred Plymouth Rock, 
and White Leghorn. Each lot of dried flesh was fed to 4 pens of 4 pigeons each, 
the proportions of flesh in the several rations being 5, 10, 25, and 30 per cent. 
The data in the table show that each of the three lots of poultry (fryers) flesh 
had a rather low antineuritic value. The rations containing 5 and 10 per cent 
respectively, had no higher antineuritic value than the check rations reported in 
Table I, while the addition of even 25 or 30 per cent of the poultry flesh to the 
other rations gave them only slightly higher values. In no case did a ration 
containing even 30 per cent of fryer flesh protect an entire pen of pigeons against 
polyneuritis for 56 days, the maximum average survival period being 34 days. 
Only one pigeon (No. 154, pen 8) out of the 48 birds reported in Table II sur¬ 
vived the test period of 56 days, and this bird was much emaciated at the close, 
having lost 35.2 per cent in weight.
