Additional 18 cattle were used as controls for gastrin study.The blood and faecal samples were collected from each animal before slaughtering , also abomasal samples with their contents were collected from each animal after slaughtering.Sample~ were subjected to parasitological, haematological ,biochemical and histopathological examination. The prevalenceand intensity of infestation, the complete blood picture, profiles of serum iron, serum proteins, serum gastrin, gastric acidity and the abomasal histopathological changes were studied.The result~ revealed that the abomasal nematodes were found in both cattle and buffaloes, but were more highlyprevalent and intensive in cattle than in buffaloes.
