Experimental coryza in broiler chickens. I. Effects of vaccination with Haemophilus gallinarum bacterin and its components on weight gains and resistance to infection.

Abstract

Effects of a Haemophilus gallinarum bacterin and its components were studied in young broiler chickens. When the bacterin was administered subcutaneously in the dorsal neck region at 2 weeks of age, no significant differences in weight gains of vaccinated and control birds were detected at eight weeks of age. In four groups vaccinated at 1, 2, 3, or 4 weeks of age and challenged with virulent haemophilus organisms 3 weeks later, the incidence of clinical signs was 30% in the vaccinates and 60% in controls. The bacterin was equally protective at the four ages of administration. Caseous plugs were found at the vaccination sites in all birds which had received adjuvant either alone or in the complete bacterin. Signs of depression lasting about 24 hours were observed in the youngest birds injected with the bacterin, but overall weight gains were normal.
