Inclusion Body Hepatitis (IBH) has emerged as an economic "thief" in livestock, causing sudden mortality and poor growth rates. Caused by Fowl Adenovirus (FAdV), IBH attacks the liver’s function. Its dual transmission routes—horizontal and vertical—and frequent subclinical cases make it particularly dangerous. Mortality ranges from 1% to 10%, climbing to 30% during outbreaks. Beyond direct losses, the virus suppresses immunity, increasing susceptibility to secondary infections like Newcastle Disease (ND) or Gumboro Disease. Economic damage is compounded by reduced feed intake and a higher Feed Conversion Ratio (FCR). Early and precise protection is therefore critical for sustainable farming.
Recognizing the need for effective solutions, Medion developed Medivac IBH Emulsion and Medivac ND T-IBH Emulsion as high-potency options. Medivac IBH Emulsion is specifically formulated with Fowl Adenovirus serotypes 8b and 11—highly homologous to prevalent field viruses in Asia, the Middle East, and Africa. This ensures a powerful defense against circulating threats.
Breeder Flock Protection: Vaccination of broiler breeders at 8, 12, and 18 weeks (observed from 3 to 10 weeks post-third vaccination) demonstrates a rapid and massive immune response. At 21 weeks, antibody titers reached 6,656 for FadV 8b and 7,168 for FadV 11, peaking at 24 weeks with a titer of 8,192 for both serotypes—significantly above the standard protective benchmark of 512. This long-lasting immunity is attributed to the optimized inactivated emulsion vaccine formulation, ensuring flock health throughout their productive life without clinical symptoms.
Progeny Protection: Trials on progenies from 28-week-old broiler breeders (10 weeks post third vaccination) confirm chicks inherit high maternal antibody titers (up to 4,096), remaining well above protective standards. This early-life protection is crucial for broilers during their vulnerable first weeks, minimizing mortality and reduced feed intake.
A trial on commercial broilers hatched from vaccinated breeders and subsequently vaccinated with Medivac ND T-IBH Emulsion at 7 days of age revealed that chicks inherited high antibody titers due to maternal antibodies. The immune response initiated at 2 weeks, providing full protection from 3 weeks onward. Medivac ND T-IBH Emulsion provides dual protection against both IBH and Newcastle Disease in a single injection .
Vaccination plays a critical role. However, optimal IBH control also requires environmental management and strict biosecurity—the first line of defense to minimize viral load. This integrated approach minimizes the threat of viral transmission, preventing losses and maximizing farm productivity.
Protecting Your Flock’s Potential: Don't let Inclusion Body Hepatitis steal your flock's potential. Medivac IBH Emulsion and Medivac ND T-IBH Emulsion provide effective protection, building a resilient foundation for optimal performance.
