  1. Data (mean ± SD) representing worm burden by sieving, percentage males and female fecundity based on the number of eggs in utero from 16 female worms per animal. The calves were experimentally infected with Ostertagia ostertagi and Cooperia oncophora and fed a tannin-rich diet (Group SF) or a control diet (Group CO)
  2. aindicates a significant difference between the groups (GLH-test: Z = -2.34, P = 0.019; Tukey)
