The relationship between avian influenza disease vaccination and chicken mortality in Sukabumi District, West Java Province, Indonesia

Abstract

Vaccination program is an important aspect in the development of chicken industry. This paper aims to analyse the relationship between vaccination program and local chicken mortality during Poverty Alleviation Program in Sukabumi District, West Java Province. Total of 3579 households in two subdistricts namely Lengkong and Cikembar were involved in this study, who received superior local chicken KUB (improved local chicken) followed by Newcastle and Avian Influenza vaccination program. Monitoring of chicken population were done during March-November 2019, while households’ characteristics data were obtained from the Ministry of Social Affairs in 2017. Descriptive and regression analysis were used to identify households’ characteristic, coverage rate and relationship between vaccination and chicken mortality. The results showed that the number of vaccinated chickens during the program significantly increased chicken mortality by 0.381 times. Even though, the coverage rate of chicken vaccination in Cikembar was higher compared to that number in Lengkong, chicken mortality in Cikembar was much greater than the other. Probably, chickens were stress or sick during vaccination program, exacerbated by poor management practices (such as lack of water and feed) notably during dry season. In conclusion, a better understanding of chicken vaccination as well as a good management practices was required to lessen chicken mortality.
