Poult Enteritis V. A. Bowes
During late winter of 1991, many local turkey growers in the Fraser Valley began experiencing health problems in their recently placed poults. Birds were both local hatch and U.S. imported. The early first-week mortality was high with an increased number of weak and cull poults. High mortality rates persisted and around 10 days of age, many flocks ran into problems with diarrhea. At this time several infectious agents were recovered from the birds, the most significant being several species of Salmonella and coronavirus. The histological lesion was varying degrees of blunting of the intestinal villi. Several antibiotic and vitamin treatment regimes were implemented with variable clinical response. Following the bout of diarrhea, which would last 5-6 days, many flocks continued to have high culling losses due to leg weakness and field rickets. Once the majority of affected birds were removed, the rest of the flock did well.
