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.

(2004) on feacal examination of 147 wild boars reported 58.5 percent of Eimeria oocysts and 83.67 percent of gastrointestinal nematodes (Oesophagostomum

Indeed, extensively managed pigs are reported to harbor intestinal helminthes and protozoans  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].
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%).
