Cecal Worms
"The Cecal worm is a common parasite of backyard poultry flocks. As the name implies, the cecal worm
inhabits the cecum of the bird. Cecal worms cause little or no damage to chicken flocks but the cecal
worm can carry the organism that causes blackhead disease in turkeys.
Earthworms ingest the infected cecal worm egg from poultry litter; turkeys that consume the earthworms
become infected with the blackhead organism. Turkeys can also become infected with the blackhead
organism from direct oral contact with the infected cecal worms. Turkeys and chickens shouldn’t be
housed together and turkeys shouldn’t range where chickens have ranged.
Leviamisole and
Ivermectin are both effective in the control of cecal worms, though both require a
veterinarian’s prescription for use in poultry"
Studies show that ivermectin is
*not* an effective poultry wormer, so not sure why they have that in their article. Per the recommendation of my vet, I treat cecal worms with Safeguard (fenbendazole) at 0.23 ml per *pound*.
