Effect of barley malt supplement on Newcastle disease vaccine antibody in Ross
broilers. Onl J Vet Res., 23
(7):675-678, 2019. Herbal extracts have been used to boost immunity in broilers. We
provided barley malt extract in drinking water to 1 day old Ross Broilers for
28 days to determine effect on antibody to Newcastle vaccine antibody. Groups
of 15 chicks were vaccinated Newcastle B1 strain intraocularly
and killed H9N2 subcutaneously at day 9 supplemented 0.2% , 0.3% or 0.5% malt
extract in drinking water. Controls were not
given extract or not vaccinated. Blood samples were taken before vaccination
and then at days 14, 21 and 28. Antibody titers (log2) were determined by Hemagglutination Inhibition test. Results suggested that 5%
barley malt supplement at all periods after
vaccination, enhanced the systemic antibody response to Newcastle disease
vaccine in Ross broilers.
