[The prophylactic effect of a morantel sustained release bolus (Paratect) on lungworm infections in vaccinated and non-vaccinated calves].
Groups of four calves received a vaccination, a vaccination combined with a morantel sustained release bolus (Paratect) together with the second vaccination dose, a vaccination combined with a Paratect bolus 14 days after the second dose, a Paratect bolus alone or remained untreated. From the faecal, serological and clinical observations it was concluded that the larval output, the course of the antibody titers against lungworm and the clinical picture of the calves which had received a bolus after or together with the vaccination did not differ from the observations in the only vaccinated calves. Calves provided with a Paratect bolus were excreting lungworm larvae in the faeces and showed mild symptoms of parasitic bronchitis. It was not necessary to treat these calves in contrast with the untreated controls.
