A CALENDAR OF LIVESTOCK PARASITES tt 
NOVEMBER 
Control worms in chickens. 
Take continued precautions against trichinosis. 
Make certain that houses to be occupied by 
livestock during winter are clean, well drained, 
and well ventilated. 
If your chickens have worms (fig. 18), as revealed by a post- 
mortem examination of one or several of them, use 2 per cent by 
weight of finely powdered tobacco dust, containing at least 1.5 per 
cent nicotine, in the dry mash to control roundworms and cecum 
worms in the flock and thus diminish the danger to young chicks 
Fic. 18.— The large 
roundworm of the 
small intestine of 
the chicken, and the 
small cecum Worm. 
Natural size 
and poults next spring. The cecum worm carries blackhead. Con- 
sult Farmers’ Bulletin No. 1330 (8). 
Beware of raw or inadequately cooked pork products! Read the 
calendar for last month and continue to take precautions to pro- 
tect yourself and your family against trichinosis. 
November is an excellent month for putting all buildings that 
are to be occupied by livestock in good condition for the winter. 
Give special attention to cleanliness, drainage, and ventilation. 
Manure is the greatest source of danger from the eggs and young of 
parasitic worms and the cysts of coccidia. Old and well-rotted 
manure may be regarded as safe so far as these parasites are con- 
cerned, and fresh manure must be regarded as dangerous. If manure 
is kept until well rotted, it should be under conditions which prevent 
fly breeding. If it is spread on the field while still fresh it should be 
plowed under promptly.
