The availability and quality of brood habitat influences survival of gallinaceous
chicks (Hurst, 1972; Everett et al.
TIDE was not included in the best supported model for gallinaceous
species (Table 1).
Strains that are highly pathogenic in gallinaceous
species may cause a range of clinical signs in other avian species, from mild illness to highly contagious and fatal disease.
When viruses harbored by ducks are transmitted to gallinaceous
species, such as chickens, severe clinical signs and high death rates can occur (10).
Cutaneous mast cell tumors have previously been documented in owls (30,31) and gallinaceous
30,31) Results of several studies have recorded differences in cell populations and morphology of marrow in gallinaceous
species compared with that of mammals, which may explain this result.
Black swans were the most susceptible species to HPAI virus (H5N1) infection, with illness, deaths, and viral distribution similar to results for gallinaceous
24,25) However, clinical disease in gallinaceous
birds has been described.
poultry are considered to be highly susceptible, whereas waterfowl may show variable clinical signs depending on the strain of infecting virus.
Growth rate in three gallinaceous
species fed diets imbalanced in calcium, phosphorus, and protein.
10) Neoplasms that affect the reproductive tract, such as oviduct-associated fibroid tumors, leiomyomas, leiomyosarcomas, adenomas, and adenocarcinomas, seem to be best documented in gallinaceous
species like domestic chickens and turkeys (Meleagris gallopavo).
TBEV has been isolated, or serologically indicated, from several bird species, especially anatids and gallinaceous
birds, and most often from Eastern Europe or Russia (9).
