Abstract
The poultry industry is the most important livestock sector in Malaysia, producing a reliable and cost-effective animal protein source supporting the country’s growing population. Besides the rising production cost due to the increase in poultry feed price, infectious diseases, especially emergence and re-emergence diseases, also pose significant threats to the commercial poultry industry. Chicken astrovirus (CAstV) is one of the new emerging viruses affecting poultry birds globally. This disease has been reported in commercial poultry farms worldwide, including in several major poultry producing countries such as the United States of America, China, Brazil, India, and Europe. However, the prevalence of CAstV in commercial chickens in South-East Asia countries, including Malaysia, is not well studied. This study aims to determine the seroprevalence of CAstV in selected commercial broiler breeder farms in Peninsular Malaysia. A total of 415 archived serum samples from broiler breeders of different ages available at the Avian Diagnostic Unit, Institute of Bioscience, Universiti Putra Malaysia, were used in this study. A commercially available indirect enzyme-linked immunosorbent assay (ELISA) that detects Group B CAstV was used to determine the antibody levels against CAstV. The ELISA antibody titers were then analysed by using One-way ANOVA. The study revealed all the tested samples were tested positive for CAstV. Statistically, there was a significant difference (p ≤ 0.05) in the antibody titers of chickens of age group 40 to 50 weeks compared to the chicken of age group less than 40 weeks age and chicken of age group more than 50 weeks of age. However, the antibody titer of chicken of the age group less than 40 weeks and more than 50 weeks were not significantly different. Since the vaccination against CastV is not available in Malaysia, and all the farms do not practice vaccination against CastV, the high incidence of CAstV indicates the flocks have been exposed to the virus. Thus, this study has provided some insight and valuable information for further research towards developing proper prevention and control measures of CAstV in poultry farms in Malaysia.
