The experiment also aimed to determine the effect of type of chickens and age of exposure to litter on the level of viral infectivity. The bioassay detected chicken anaemia virus, infectious bursal disease virus and fowl adenovirus from chicken litters. SPF chickens showed higher sensitivity than commercial broiler chickens without any effect of age of exposure, however, the assay was more sensitive in broiler chickens when exposed at day 8. We conclude that the bioassay based on exposure of day-old SPF chickens is a viable assay of viral infectivity of poultry litter. | Publication Type: | Conference Publication | Conference Details: | APSS 2009: 20th Annual Australian Poultry Science Symposium, Sydney, Australia, 9th - 11th February, 2009 | Source of Publication: | Proceedings of the Australian Poultry Science Symposium, v.20, p. 176-179 | Publisher: | University of Sydney | Place of Publication: | Sydney, Australia | ISSN: | 1034-6260 1034-3466 |
