Abstract

Daily changes in serum gastrin and pepsinogen concentration were studied during 2 types of infection with O. ostertagi in calves. In a first experiment 2 calves were trickle infected (10 times 10 000 L3 Ostertagia) and 2 animals received a single infection of 100 000 L3 Ostertagia. Gastrin and...

Four groups of calves were infected with either 5000 (Group A), 10 000 (Group B), 20 000 (Group C) or 40 000 (Group D) infective larvae (O. ostertagi L3)...
