Evaluation of Antibody Production against Newcastle Disease Virus after Immunization with Different Vaccines in Fayoumi Chicks

Evaluation of maternal antibody levels for establishing the vaccination program against Newcastle disease in ostrich chicks

  Newcastle disease virus (NDV) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in Iran. Therefore, establishing a routine vaccination program against ND in ostrich flocks would be useful in order to reduce the danger of this infection. Newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losse...

Effects of High Dietary Levels of Selenium and Copper on Growth Performance, Selected Blood Biochemical Parameters and Antibody Production Against Newcastle Disease Vaccine Virus in Broiler Chickens

An experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against Newcastle disease vaccine (NDV) virus in broiler chickens. A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

Evaluation of Quality of Two Commercial Oil-Emulsion Newcastle Disease Vaccines In-vivo and In-vitro

Background and Aims: Newcastle disease (ND) is a highly contagious disease in poultry with economic losses in the world. Vaccination is one of the most important ways for prevention and control of NDV, but there are reports of ND outbreaks in vaccinated chickens. Poor quality of the vaccines is one of the reasons of vaccine failure. In this study the quality of two commercial oil-emulsion Newca...
