Abstract
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 0th day of vaccination. Serum antibody titer in the vaccinated goats started rising gradually from the 14th 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.
Highlights
Peste-des-petits-ruminants (PPR) is an important contagious viral disease of goats and sheep, often associated with high morbidity and mortality and was first reported in sheep and goats, in 1942, in Côte d’Ivoire, West Africa

Summary
Peste-des-petits-ruminants (PPR) is an important contagious viral disease of goats and sheep, often associated with high morbidity and mortality and was first reported in sheep and goats, in 1942, in Côte d’Ivoire, West Africa. It is emerging in new regions of the world, causing significant economic losses [1] and threatens the food security and sustainable livelihood of farmers across Africa, the Middle East, and Asia [2].
