Pullets Reared in Aviary Systems -
Anticoccidial Drugs

This information is NOT a housing management guide. These sections were created to help explain the relationship between housing and oocyst ingestion. Please consult your veterinarian and bird management guide from the breeding company for housing management information.

Brooding

General Good Barn Practice Provide chicks with clean, biosecure housing. Ensure that feed and water are readily available to the chicks when they are placed (1). Additionally, proper heat, ventilation and lighting as well as feed and water quality are required for good rearing management (1).

Physical Enriched Cage Environment During Brooding: Nipple Drinker Cups If nipple cups are attached to the drinkers this is a potential reservoir for oocysts.

General Good Practice for Coccidiosis Management During Rearing

Physical Enriched Cage Environment: Perches, Platforms and Dust Bath Areas - As the pullets grow to use the perches, platforms and dust bath areas fecal build-up may occur on or below these additions. Consequently, it is important to note these areas as potential reservoirs for oocysts. Additionally, this elevation may allow the birds defecate on each other which could be another way in which birds could ingest oocysts (2).

Figure 1. An example of a platform in an aviary pullet rearing system during use.  Fecal build-up can occur on this platform during rearing and if the feces are contaminated with infective oocysts this platform is another area where pullets can ingest oocysts.
