Newcastle disease virus (NDV) infects most avian species. The serious consequence is the disease (frequently fatal) that occurs when virulent strains of the virus infect domestic chickens. The epidemiology of Newcastle disease (ND) in commercial chickens is fairly well understood. Infected chickens are the usual source of virus, which can be transported mechanically by fomites or by people. Pre...

Highly pathogenic avian influenza (HPAI), subtype H5N1, was first officially reported in Indonesia in 2004. Since then the disease has spread and is now endemic in large parts of the country. This study investigated the statistical relationship between a set of risk factors and the presence or absence of HPAI in Indonesia during 2006 and 2007. HPAI was evaluated through participatory disease su...

Participatory research on vaccination of village poultry against Newcastle disease (ND) was carried out in the village of Disaneng, in the North West Province of South Africa. Three application methods for ND Inkukhu vaccine were shown to induce sufficient levels of immunity in back-yard poultry when correctly administered. These are eye-droplet administration to individual fowls, in-feed and i...

This study examined constraints and adoption in poultry production in the Northern Agricultural Zone of Delta State, Nigeria. A sample size of 80 respondents comprising of Supervisors of selected farms was used for the study. Data were collected through the use of a structured and validated questionnaire. Data were collected in March 2017. Descriptive statistics such as frequency count, mean sc...

This study examined flock size and management, level of internal and external parasite burden and seroprevalence of antibodies to poultry pathogens in indigenous chickens in Bokaa village, Kgatleng district, Botswana. The mean flock size was 22.6 +/- 6.85 with a range of 11-34. The mean body weights of cocks and hens were 2.28 +/- 0.56 kg and 1.70 +/- 0.38 kg, respectively. Housing and commerci...

INTRODUCTION The Asia-Pacific region is the likeliest location for the next significant outbreak of highly pathogenic avian influenza (HPAI). Indonesia has experienced HPAI H5N1 outbreaks in poultry and humans each year since 2003 and has had the highest case fatality rate for human cases. The purposes of this study were to capture the knowledge of avian influenza and of poultry-raising practic...

Egg Drop Syndrome 1976 (EDS76) is a viral disease of laying birds characterized by a sudden drop in egg production, failure to achieve peak production and the laying of poor quality eggs. It has been reported to affect a wide range of birds including turkeys and layers and is a major constraint to the profitability of egg production in both commercial and village laying birds. This paper is a r...

This paper briefly reviews the advantages and limitations of the different vaccines available for use against Newcastle disease in village chickens. Inactivated vaccines give very good immunity without vaccinal reactions and have been widely used, but are relatively expensive and require training to apply. Live vaccines are easy to apply and relatively inexpensive, and give moderately good immu...
