Assessment of immune response to a lyophilized peste-des-petits-ruminants virus vaccine in three different breeds of goats

AIM: Immune response to a lyophilized peste-des-petits-ruminants virus (PPRV) vaccine was evaluated in three different breeds of goats. MATERIALS AND METHODS: Three breeds of goats consisting six number of animals in three groups, i.e., Group A (local Assam hill goat), Group B (cross-bred), and Group C (Beetal goats) were randomly selected for evaluating the immune response to a lyophilized PPRV vaccine. RESULTS: A higher rise in the overall mean serum antibody titer was observed in Group A (40.50±3.74) than in Group B (37.58±37.58) and Group C (35.90±3.29) during the study period. CONCLUSION: Initially, a negative PPRV specific serum antibody titer was recorded in all the groups at 0(th) day of vaccination. Serum antibody titer in the vaccinated goats started rising gradually from the 14(th) day post vaccination. Later higher rise in the overall mean serum antibody titer in Group A (local Assam hill goat) lead to the conclusion that higher serum antibody titer in local non-descript breed might be due to their better adaptation to the environmental condition.
