Abstract

파유미 종 닭에 계두 및 구두 백신을 접종하고 2종의 백신에 대한 방어 능력을 방글라대쉬의 야외의 닭 사육 조건에서 비교하였다. 'Take reaction'의 수율을 평가하여 이것을 더 나은 면역 반응과 관련지어 해석하였으며, 그룹 B와 그룹 C의 닭은 각각 93.33%와 100%의 면역 반응을 보여주었다. 1차 예방접종에 따른 평균 PHA 항체가는 B와 C 그룹에서 각각 <TEX>$32{\pm}14.81$</TEX>과 <TEX>$33{\pm}13.66$</TEX>으로 나타났다. 보강 접종 후 평균 PHA 항체가는 B 및 C 그룹의 전 처리군에서는 <TEX>$46.93{\pm}16.52$</TEX>와 <TEX>$55.46{\pm}14.64$</TEX>이었으며, 공격접종 2주 후 시점에서 향체가는 각각 <TEX>$93.86{\pm}33.04$</TEX>와 <TEX>$110.93{\pm}29.29$</TEX>로 나타났다. PHA 항체가는 백신 접종 후와 접종 후 처치군들에서 백신접종 전 항체가에 비해 현저하게 증가함을 보여주었다. 이렇게 현저한 PHA 항체가의 차이는 사용한 백신의 종류가 다양함으로 인해 발생되는 것이기도 하였으나, 백신 접종을 받은 모든 닭들은 감염에 대한 저항력을 보여주었다. Fayoumi chicks were vaccinated with fowl pox virus vaccine and pigeon pox virus vaccine. The protective potentiality of the two vaccines was compared in field condition in Bangladesh. The percentage of 'take reaction' was assessed to conclude its relationship with better immune response and recorded 93.33% and 100% in birds of group B and group C, respectively. The mean passive hemagglutination (PHA) antibody titre after primary vaccination was <TEX>$32{\pm}14.81$</TEX> in group B and <TEX>$33{\pm}13.66$</TEX> in group C. Following booster vaccination, the mean PHA titres level at pre challenge of group B was <TEX>$46.93{\pm}16.52\;and\;55.46{\pm}14.64$</TEX> in group C. The PHA titre of group B and C at two weeks post challenge recorded <TEX>$93.86{\pm}33.04\;and\;110.93{\pm}29.29$</TEX>, respectively. PHA titre significantly (P<0.01) increased after vaccination and post challenge compared to pre- vaccination titre. There was significant variation (p<0.01) of PHA titre at pre challenge in these groups using different vaccine combinations, but all the vaccinated birds resisted challenge infection.
