چکیده
Materials and methods: Two hundred litters of piglets on a commercial breeder farm (Site One) were randomly allocated to two treatment groups: nonvaccinated or vaccinated with MH vaccine at 4 days of age and at weaning (off-label use of the vaccine). At weaning, treatment groups were commingled in two nursery barns on Site Two, segregated by gender (875 castrates, 911 females). At 8 weeks, vaccinates and nonvaccinates were randomly was greater in vaccinates by AU$5.14 per pig.

متن کاملEfficacy of Mycoplasma hyopneumoniae vaccination before and at weaning against experimental challenge infection in pigs
BACKGROUND Commercial bacterins are widely used at weaning to control Mycoplasma hyopneumoniae infections in pigs. However, it is not known whether the efficacy of vaccinating against M. hyopneumoniae can be influenced by the weaning process when vaccination is applied at the day of weaning. The present study assessed the efficacy of a single M. hyopneumoniae vaccination (Ingelvac MycoFLEX®) th...

BACKGROUND Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary agent of enzootic pneumonia in pigs. Pigs are often infected with different M. hyopneumoniae strains. This study assessed the efficacy of vaccination against experimental infection with two genetically different M. hyopneumoniae strains in weaned piglets. At 33 days of age (D0), 45 M. hyopneumoniae-free piglets were randomly ...
