本文介绍了奇布托村家禽的管理措施和2005年1月至2008年8月期间进行的纽卡斯尔病疫苗接种计划的影响。在莫桑比克Chibuto参与纽卡斯尔病疫苗接种计划的11个村庄进行了一项51个问题的调查。平均羊群规模显着较高的家庭，为他们的鸡提供饲料（15.0）比鸡，只清除（8.7; P = 0.0001）。平均鸡群规模显着高于家庭接种疫苗的鸡（16.9）比那些未接种疫苗的鸡（10.0; P = 0.0005）。在最近一次育雏期间孵化的小鸡的平均数量显着高于家庭喂养他们的鸡（9.2）比鸡，只孵化（6.9; P = 0.0335）。平均孵化率显着较高的家庭接种疫苗的鸡（0.8）比那些未接种疫苗的鸡（0.7; P = 0.0324）。经测定，未接种疫苗的鸡死于纽卡斯尔病的风险约为未接种疫苗的鸡的5倍（比值比= 4.79）。本研究支持I-2纽卡斯尔病疫苗的有效性，表现为平均鸡群规模增加和纽卡斯尔病导致的鸡死亡率降低。农民的参与程度和社区疫苗接种人员的持续承诺表明，Chibuto疫苗接种计划可能在中长期内可持续。
This paper describes the management practices of village poultry in Chibuto and the impact of the Newcastle disease vaccination program conducted between January 2005 and August 2008. A 51-question survey was conducted in 11 villages involved in the Newcastle disease vaccination program in Chibuto, Mozambique. The mean flock size was significantly higher in households that provided their chickens with feed (15.0) than chickens that only scavenged (8.7; P = 0.0001). The mean flock size was significantly higher in households with vaccinated chickens (16.9) than those with unvaccinated chickens (10.0; P = 0.0005). The average number of chicks hatched during the most recent brooding was significantly higher in households that fed their chickens (9.2) than chickens that only scavenge (6.9; P = 0.0335). The mean hatch rate was significantly higher in households with vaccinated chickens (0.8) than those with unvaccinated chickens (0.7; P = 0.0324). It was determined that unvaccinated chickens are approximately five times more at risk to die of Newcastle disease (odds ratio = 4.79). This study supported the efficacy of the I-2 Newcastle disease vaccine as shown by the increased average flock size and decreased incidence of chicken mortality due to Newcastle disease. The level of farmer involvement and ongoing commitment by community vaccinators suggest that the Chibuto vaccination program is likely to be sustainable in the medium- to long-term.
