Digestive strongyles are parasitic diseases caused by strongylid nematodes that include a number of parasitic species, (such as Haemonchus, Ostertagia, Trichostrongylus, Cooperia, Nematodirus, Bunostomum,
Oesophagostomum, etc.) and are among the bovine parasites most commonly encountered in temperate regions.
En el cultivo de larvas de ovinos adultos de agosto de 2014 se obtuvieron las siguientes frecuencias:
Oesophagostomum columbianum 41%, Trichostrongylus columbiformis 25%, Chabertia ovina 13%, Ostertagia ovina 12 % y Teladorsagia circumcincta 9%.

Indeed, extensively managed pigs are reported to harbor intestinal helminthes and protozoans [7] while pigs raised in intensive operations though thought to be less prone to gastrointestinal infestation are infested as well; the large roundworm (Ascaris suum), whipworm (Trichuris suis), the nodular worms (
Oesophagostomum sp), and protozoa (Coccidia) are often found in intensive pig production [8, 9].
Los generos de nematodos identificados en los cultivos de larvas sin el previo enfriamiento de la heces correspondieron a Haemonchus (58.1%), Trichostrongylus (32.5%),
Oesophagostomum (5.8%) y Nematodirus (3.4%).
Raza et al.(2013) reported that age-wise prevalence of different GI nematodes in calf like Toxocara vitulorum was 25.64% while in adult animal it was 8.19%,
Oesophagostomum radiatum was 2.56% in calf as compared in adult animal (3.27%), Haemonchus placei was 2.56% in calf as compared to adult (0%) and Bunostomum phlebotomum was 2.56% in calf compared to adult (1.63%).
