Lot 5 was fed in December, January, and February. Lot 6 was fed 
from March io, when there was considerable grass, etc., in the yards. 
This enabled the animals to obtain food aside from the cottonseed mix¬ 
ture, and possibly explains why deaths were not so frequent as during 
a similar period in lot 5. 
GENERAL EFFECT ON HEALTH OF HENS 
Dr. Kaupp comments on the lots at the termination of the experiment 
as follows: 
Lots 5 and 6 suffered with pendulous crops, became sick of the feed, and all of lot 
5 died. Lot 6 was following a similar route when discontinued. The birds in this 
lot were down in vitality. 
Lot 1 was in good physical condition except hen 8, which was suffering from pendu¬ 
lous crop. All the birds in lots 2 and 3 were in good physical condition. The birds 
of lot 4 suffered from pendulous crops, hen 19 being the worst. All the birds affected 
fully recovered, and were in good physical condition after a few days’ feeding of 
normal rations for fowls. 
There seems to be variance of opinion as to whether cottonseed meal 
is injurious to fowls. We may suggest that this is due to the use of 
different cottonseed meals. Thus, Hartwell and Lichtenthaeler (j), 
Clayton (i), and Osborne and Mendel (7) found no sign of toxicity. 
Kaupp (4), of this Station, has reported a high death rate among birds 
receiving large amounts'of cottonseed meal, compared with control 
fowls fed on similar diets containing linseed meal.
