Nodular Worms

Oesophagostomum spp. are about an inch long when they reach their adult stage in the large intestine. This parasite is most common in herds where sows are outside during their gestation period or are in heavily bedded areas. The eggs of the nodular worm, which are passed in feces, are not as hardy as those of the roundworm and whipworm. They require bedding, manure, or some other form of protection from desiccation. When conditions are right the egg will form a larvae within a week that can then be swallowed by a pig. The larvae migrate to the large intestine and burrow into the walls forming nodules. This can decrease feed efficiency costing up to $3.69 per animal.

Infected pigs may have diarrhea, decreased appetite and poor weight gain. Piglets as young as two to three week of age can be infected leading to a grayish-yellow diarrhea. This problem can be corrected by treating infected sows and improving the hygiene of the farrowing crates
