Immunomodulatory Effects of Lisovit in Response to Newcastle Disease and Infectious Bursal Disease Vaccines in Broilers
The present study was designed to investigate effects of Lisovit (Biomin, Austria) on the immune system of broiler chickens. For this purpose, 270 (day-old) broiler chicks were randomly divided into three groups A, B and C of 90 birds each. The birds were vaccinated against Newcastle Disease (ND) on day 3 (intraocular) and day 18 (drinking water) of age and against Infectious Bursal Disease (IB...
متن کاملSynbiotic 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 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 کاملComparison of Pathogenicity and Serologic Response of Four Commercial Infectious Bursal Disease Live Vaccines.
Various commercial vaccines for immunization of broiler chickens against infectious bursal disease (IBD) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. In this study the pathogenicity and serologic response of four IBD vaccines, cloned D78®, Bursine-2®, Bursimune® and Cevac Gambo-L®, were evaluated in specific pathogen f...
متن کاملInfectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines
The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed at evaluating the pathogenicity and immunogenic...
