Effects Upon Egg Production.
toup is a disease that ordinarily
IS not accompanied by a high death
rate, although the mortality varies
considerably in individual flocks. In
Acks where a particularly viruleni
Afection is causing the trouble. and
where the resistance Of the birds Is
low, because OF faulty feeding. hous
ing, and management, the mortalit,
will run very high.
Although roup and pox are dis.
eases which ordinarily and under
good conditions are accompanied by
low death-rate. the effects upon
egg production are very marked
Usually, there is a marked decrease
in the egg production.
