• Therefore, during the simulation of our models, we take samples from individual calves according to the actual sampling dates.

• Therefore, we introduce calves into our models according to their actual dates of birth.

• Weaned beef and dairy calves have been reported to have a higher prevalence of infection than unweaned calves [22, 25, 44].

• Even more prominent differences were observed between calves infected with the above-mentioned isolates.

• The parasite mainly affects first grazing season calves causing diarrhoea, malabsorption of nutrients and, in severe cases, death.

• Evidence for genetic control of nematode eggshedding rates in calves.

• Nevertheless, calves from all groups developed serious disease following the challenge infection.

• Finally, although a substantial degree of immunity was induced by the primary infection, it was insufficient to protect calves from lungworm disease after challenge.

• Eight calves cloned from somatic cells of a single adult.

• Production of cloned calves following nuclear transfer with cultured adult mural granulosa cells.

• In addition, there were more than 50 young cattle over 1 year old and 28 calves under 1 year old.

• During this farm study, individual calves were born into the cohort at different times.

• Calves as well as piglets were obtained from commercial herds.

• To confirm the immune status of the calves, reductions in worm burdens were measured after treatment with benzimidazoles at housing and at subsequent challenge infection.

• Calves were considered to have seroconverted in the period immediately prior to their first positive sample.
