Winter Ostertagiasis in Swedish Cattle

  • Olle Nilsson
Part of the Current Topics in Veterinary Medicine and Animal Science book series (CTVM, volume 9)


Young cattle on permanent pastures in Sweden are exposed to substantial numbers of Ostertagia spp. larvae in the autumn, and these are inhibited at the fourth larval stage. Nevertheless, Type II ostertagiasis is regarded as an uncommon disease. One explanation for this may be that the condition has been overlooked hitherto because the resumption of development of the worms starts in May when the animals are at grass again.
