The study was undertaken to evaluate the effect of naked neck gene on mortality, cell
mediated and humoral immune response in white plumage broiler population. The mortality
of homozygous naked neck (Na/Na) broilers (11.71%) was comparatively lower than that of
heterozygous naked neck (Na/na)(12.28%) and normally feathered (na/na)(13.59%)
broilers. The humoral immune response was measured against (1% v/v) sheep red blood
cells (SRBC) for total haemagglutinin (HA) antibody, 2-mercaptoethanol resistance (MER) or …
