Dustbathing in Relation to Early Pecking Experience in Game Pheasants (Phasianus colchicus)

Growth and development of young game pheasants (Phasianus colchicus)

Fifty game pheasants were kept to 8 weeks in confinement housing and later maintained outdoors in a partially roofed aviary. Pheasants received commercial feed mixtures ad libitum. Body weight and dimensions were determined every 4 weeks. Ten pheasants were selected for slaughter at the end of 18 and 20 weeks each. After slaughter, their heads, shanks, feathers, blood, inedible viscera and majo...

Serological evidence of exposure to zoonotic tick-borne bacteria in pheasants (Phasianus colchicus).

INTRODUCTION AND OBJECTIVE Previous studies on tick-borne pathogens in the avian population have focused mainly on the detection of the agents in ticks collected from birds, but data about the presence of tick-borne bacteria in these animals are scant. The aim of the presented study was to verify the exposure to some zoonotic tick-borne bacteria, in particular, Anaplasma phagocytophilum, Borrel...

Consequences of prenatal androgen exposure for the reproductive performance of female pheasants (Phasianus colchicus).

Maternal hormones in vertebrate eggs can mediate important forms of maternal effects. However, the function of hormone transfer to the eggs is still debated, especially because long-term fitness consequences have been little studied. We investigated the effect of prenatal exposure to physiologically elevated yolk testosterone (T) levels on reproduction of female pheasants (Phasianus colchicus) ...

An outbreak of avian tuberculosis in peafowl (Pavo cristatus) and pheasants (Phasianus colchicus) in a zoological aviary in Turkey

Avian tuberculosis was diagnosed histopathologically and microbiologically in two pheasants (Phasianus colchicus) and two peafowl (Pavo cristatus) kept in the same aviary. The incidence of avian tuberculosis in the aviary was 6%. Non-mineralized caseogranulomas were present in the liver (3 cases), spleen (3 cases), intestine (2 cases), lung (2 cases), and cloaca (1 case). Granulomas in the lung...
