Behaviour patterns of the cage-housed breeding flock of 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...

Effect of sight barriers in pens of breeding ring-necked pheasants (Phasianus colchicus): I. Behaviour and welfare.

1. The study investigated the effects of providing sight barriers in breeding pens on pheasant mortality, feather damage and behaviour. 2. Data were collected from 11 conventional pens (control) and 11 pens with additional sight barriers (barrier) over the course of a ten week breeding season. Each pen contained 8 males and 56 females at the beginning of the season. 3. There was a higher rate o...

Effects of spring supplementary feeding on population density and breeding success of released pheasants <i>Phasianus colchicus</i> in Britain

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) ...

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...
