Remember that adult animals harbor various 
parasites and may show little evidence of them; 
but such pests soon spread to young stock, caus- 
ing heavy losses. 
Put young animals on clean, safe pastures. 
Keep young chicks away from turkeys and areas occupied by 
turkeys if you want to avoid losses by gapes, as turkeys commonly 
harbor gapeworms (fig. 5) even though they show no signs of gapes. 
Adult and young turkeys may carry gapeworms without evident 
bad effects in many cases, and hence 
serve as carriers, but adult chickens 
are practically immune and can not 
serve as carriers. Chicks are highly 
susceptible to gapeworm infection 
as a rule, acquiring the infection 
from turkeys; the worms are deadly 
to chicks. Write for Farmers’ Bul- 
letin No. 1337 (7). 
If birds are lousy, treat sitting 
hens before chicks hatch. 
Early hatching helps to diminish 
losses from parasites. 
Put all young livestock—lambs, 
calves, colts, etc.—on clean, safe,

and away from areas occupied by 
older animals during the past year or which have not been sown to 
a fresh crop since so occupied. The older animals usually harbor 
worms and may show little evidence of the fact, but young animals 
are highly susceptible to worm infections and to the bad effects 
from them. The infective material (worm eggs and young worms) 
passes in the manure on to the pasture, and hence contaminated pas- 
tures are dangerous to young animals. 
If you allow your dog or cat to play with your child, keep the 
animal as free from worms as you keep the child. Certain dog and 
cat tapeworms, in association with fleas and biting lice, are com- 
municable to man and are most commonly found in children who 
associate with dogs and cats. Certain roundworms of dogs and cats 
are sometimes found in man, usually in children. Your veterimarian 
can tell you whether your dog or cat has worms.
