ABSTRACT
An acute upper respiratory disease was observed in two broad-breasted white (BBW) turkey primary breeder flocks. Associated clinical signs included sneezing, depression, and a deep dry cough originating from large conducting airways. Morbidity reached approximately 15-20% of the hens in an affected house. None of the turkeys died, and total feed consumption was not affected. A minimal effect upon egg production was noticed. Sera from an acutely affected flock exhibited a marked rise in titer to Bordetella avium compared with preinfection sera samples. In Case 1, B. avium was isolated in pure culture from affected birds. In Case 2, B. avium was diagnosed by serological results and clinical signs; bacteriological examination was not attempted. The findings presented here are consistent with an acute clinical outbreak of B. avium-induced turkey rhinotracheitis (turkey coryza) in BBW turkey breeder hens.

Several blood parameters were determined for 12 1-year-old and 12 7-year-old partridges to establish base line values on blood chemistry of this species. After taking blood samples, the 7-year-old birds were killed and necropsied for gross examination. With aging, there was a significant increase in plasma glucose, glutamic-oxalacetic transaminase (GOT), potassium, cholesterol, uric acid, and albumin. Males generally had a significantly lower lactic dehydrogenase (LDH) than females. The 7-year-old males had a significantly higher plasma cholesterol and GOT than 1-year-old males. There were no differences in plasma potassium, sodium, and calcium between partridges and data previously reported for chickens. Blood glucose levels in young and old partridge appear to be twice that for chickens, whereas cholesterol and lactic dehydrogenase levels were much lower in chickens.

Poults were protected against challenge with Arizona hinshawii 7:1,7,8 inoculated into the yolk sac 30 hours post-hatching by preincubation streptomycin treatment of turkey eggs, administered by temperature-differential egg dipping in a solution composed of 250 ppm of a quaternary ammonium compound, 10 ppm of ethylenediaminetraacetate and streptomycin at 9 mg per ml. Mortalities at 17 hours and 22 days postchallenge were respectively 8% and 44% in poults from treated eggs vs 47% and 93% from untreated eggs. Liver isolation rates at 17 hours and 22 days postchallenge were respectively 0% and 16% in poults from treated eggs, vs 71% and 80% from untreated eggs.
