An experiment was carried out to examine the significance of resistance to Cooperia spp. for the weight gain performance of calves under conditions of severe re-infection with several species. Part of the variation in weight gains could be explained by variation in resistance. Resistant animals that showed a transient growth-depression after primary infection, ultimately performed better.
