Question 1
1.1 Internal parasites of pigs, excluding tapeworms, and their location
Parasite Location in body
Small intestine (sometimes biliary ducts and
Ascaris suum (large roundworm)
stomach)
Oesophagostomum spp.
Large intestine
(nodular worms)
Metastrongylus apri (lungworm) Lungs
Trichuris suis (whipworm) Large intestine
Strongyloides ransomi Small intestine
Stephanurus dentatus (kidney Kidneys and peri-renal fat (also liver, pancreas,
worm) ureters, sometimes spinal cord)
Gastrodiscus aegyptiacus (fluke) Small intestine and colon
1.2 Internal parasites transmitted to the young via mother's milk
• Strongyloides westeri (horses) — "Foals are infected primarily through milk"
• Strongyloides ransomi (pigs) — "the parasite is transmitted chiefly through the
milk"
1.3 Influence of internal parasites on performance
From the guide's introduction: worms significantly affect intensively farmed pigs,
chickens and ostriches if animals are sold even a few days later than planned due to
infestation, the farmer's profit is much smaller. In horses, worm infestation
detrimentally affects performance as working animals and can seriously affect
racehorses. In all species, heavy infestation can even cause death, resulting in direct
losses.
