Two commercial Lasota strain Newcastle Disease (ND) vaccines namely Lasota vaccine-1 and vaccine-2 and two
Mukteswar Newcastle disease vaccines namely Mukteswar vaccine-1 and vaccine-2 were evaluated fort their efficacy
and influence on productive performance of broilers. For this purpose, total of 75 broilers day-old chicks were
distributed into five equal groups tagged as A, B, C, D and E respectively, each group was further divided into 3
subgroups containing 5 birds per subgroup respectively. The birds in groups B, C, D and E were actively immunized
against ND with Lasota-1, Lasota-2, Mukteswar-1 and Mukteswar-2 respectively, on days 10 and 21 through ocular
route, leaving A as control group leaved unvaccinated. The serum HI antibody response to these four vaccines was
determined on day 21st and 35th day of the experiment. According to th.. View More»
