title: Changes in serum pepsinogen and haemoglobin concentrations in calves infected with Haemonchus contortus.
abstract: In four calves given Haemonchus contortus larvae, the serum pepsinogen concentration rose quickly to reach a mean of 3.5 iu tyrosine on day 14 after infection. The mean concentration dropped to 1.8 iu tyrosine by day 23 and remained around 2.0 iu tyrosine until an anthelmintic was given on day 57, when concentrations returned to preinfection values.
