Convenient – A single vaccination is all that is required for the lifetime of the animal. No boosters or annual revaccination is required.
Dual action – Gudair Vaccine has been extensively trialled and proven to reduce Johne’s deaths by at least 90% in field trials1,2. Gudair Vaccine reduces the shedding of Johne’s bacteria in the faeces of infected animals by at least 90%1,2, thereby reducing disease transmission and new infections.
Cost effective – Field experience in NZ and Australia shows that Johne’s losses become insignificant in vaccinated stock. A positive return on investment is expected in flocks experiencing 1% losses or greater.
Well tolerated – Gudair Vaccine can be used in sheep from one month of age.
Nil withhold – Gudair Vaccine has the added advantage of a nil milk and meat withhold period.
Gudair Vaccine is an inactivated vaccine containing a suspension of the micro-organism, Mycobacterium paratuberculosis, strain 316F, inactivated by heat and adjuvanted with mineral oil in a multiple emulsion. It contains 2.5mg of dried micro-organism per mL. Thiomersal is used as a preservative.
Gudair Vaccine is presented in 100mL and 250mL pillow packs.
Animals treated with this vaccine are likely to give positive results when tested for tuberculosis or Johne's Disease. After vaccination a firm swelling develops at the site of injection. Therefore, as a result of the vaccination, it is normal for a nodule to appear after 7–15 days and it may become greater than 5cm in diameter. When this vaccine is injected into infected animals, a more intense local reaction (secondary immune response) should be expected. In some animals the swelling may develop into an abscess and burst. This may attract flies and vaccinated animals should be checked regularly for flystrike and be treated where necessary. Vaccinated animals, if sent for slaughter, may be subject to downgrading due to vaccination site reaction in the regional lymph nodes. Attention to good vaccination technique will minimise the risk of this occurring.
