Abstract

Relationships among short-term fasting heat stress and response to infectious bursal disease (IBD) vaccinations were studied in broiler chicks. Commencing from 28 days of age birds fasted from 0900h to 1700h or fed ad libitum were exposed to high ambient temperatures (362C) from 1200h to 1700 h or unheated (minimum 25C; maximum 34C) as controls. Live IBD vaccine (Nobilif strain D78 Intervet International B. V. Boxmeer Holland) was given intraocularly at 14 and 28 days of age. On day 35 while feeding regimen had negligible effect on immune response the heat treatment suppressed antibody titers. On Day 42 feed-restricted chicks had higher antibody response to IBD vaccinations than those fed ad libtitum in response to the heat exposure.
