The incidence of anemia and polycythemia was established in clinically ill Georgia broilers that were tested for packed cell volume (PCV) during 1988 and 1989. More than 66% (324/488 = 66.4%) of PCV-tested broiler chicks were anemic, and less than 2% (8/488 = 1.6%) of PCV-tested chicks were polycythemic. The incidence of anemia was significantly (P less than 0.001) higher than expected (2.5%) at age 7 days (56.9%), 14 days (83.9%), 21 days (74.7%), 28 days (58.7%), and 35 days (57.9%). The incidence of polycythemia was significantly (P less than 0.001) higher than expected (2.5%) in 35-day-old broilers (21.1%) but was not significantly different from the expected rate in broilers at age 7 days (0%), 14 days (1.8%), 21 days (0.3%), and 28 days (4.3%). The established rates for anemia were much higher than we would have hypothesized. This led us to believe that either 1) an etiology for anemia is present in epizootic proportions in Georgia broilers, or 2) the standard method for establishing reference intervals for anemia in animals does not apply to broiler chicks.
