Lohmann gumboro vaccine show positive sero-response in poultry
Veterinarians have found that by inducing Lohmann's AviPro IBD Xtreme earlier, there are results of higher sero-response in poultry as it was able to break through the high maternal antibodies when used earlier.
Production parameters of AviPro IBD Xtreme-vaccinated broilers were comparable with those of broilers vaccinated with other intermediate-plus vaccines.
Veterinarian Herman Block said infectious bursal disease (IBD), also known as gumboro, is one of Germany's major problems in the poultry industry and could cause significant economic losses for farmers, adding that vaccination is encouraged.
Block commented that depending on maternal immunity, they were able to use the vaccination between one and two days earlier which provided good protection without any loss of performance.
Block and his colleagues take 49,000 blood samples a year in northern Germany to determine the optimum time for vaccination.
Field studies were carried out involving 3 commercial intermediate-plus vaccines to investigate their efficacy on 3 separate broiler farms.
