Synbiotic enhances immune responses against infectious bronchitis, infectious bursal disease, Newcastle disease and avian influenza in broiler chickens
Increased susceptibility of birds to avian pathogens in intensive husbandry system has emphasized on necessity of improvement of innate and specific immune responses of birds by the fast establishment of a beneficial microflora and immune stimulator factors to guarantee healthy and low-price products. During this study, 192 one-day-old broiler chicks (Ross-380) in four groups with three replica...
متن کاملCharacterization of variant infectious bursal disease virus from a broiler farm in Japan using immunized sentinel chickens
We attempted the isolation of variant infectious bursal disease (IBD) viruses by using sentinel chickens immunized with inactivated classical-type IBD vaccine. Immunized sentinel chickens with high levels of neutralizing antibodies and non-immunized sentinel chickens were raised together with broiler chickens in a commercial farm. Severe atrophy of the bursa of Fabricius was observed from the s...
متن کاملNewcastle Disease Virus Vectored Bivalent Vaccine against Virulent Infectious Bursal Disease and Newcastle Disease of Chickens
Newcastle disease virus (NDV) strain F is a lentogenic vaccine strain used for primary vaccination in day-old chickens against Newcastle disease (ND) in India and Southeast Asian countries. Recombinant NDV-F virus and another recombinant NDV harboring the major capsid protein VP2 gene of a very virulent infectious bursal disease virus (IBDV); namely rNDV-F and rNDV-F/VP2, respectively, were gen...

متن کاملConjugated linoleic acids alleviate infectious bursal disease virus-induced immunosuppression in broiler chickens.
The immunoregulatory actions of conjugated linoleic acid (CLA) of relevance to viral disease pathogenesis and immune responses were investigated. To test the hypothesis that CLA ameliorates immunosuppression, we developed a viral challenge model by infecting chickens with infectious bursal disease virus (IBDV). After 14 d of dietary supplementation with either soybean oil or CLA, half of the ch...
