Poultry intestinal ascaris
Intestinal parasites are insects phylogenically adapted to internal environments and, in consequence, antiparasitics are toxic substances that, moreover than affecting the parasite, also do the same with birds liver, laying and fertility too. This is why antiparasitic programs should combine with a correct management of litter
to decrease parasitic reinfestation. Notice in the photos, moreover than ascaris, yellow foam and the named "mucose of bar", typical for intestine parasitic status.
