Body Weight and Some Biometrical Traits of Ring-necked Pheasants (Phasianus colchicus) at Different Ages (original) (raw)
Body weight and some biometrical traits of ring-necked pheasants (Phasianus colchicus) at different ages. Folia biologica (Kraków) 60: 79-84. Although the growth of pheasants is an important issue, there are few publications providing information on body weight and morphometrics of pheasants at different ages. The aim of this study was to investigate body weight, tarsus length, wing length and wingspan in farmed pheasants aged 3-16 weeks. The study was carried out on 50 pheasants (31 females and 19 males). All one-day old birds were marked and kept until the 16 JD week of life. In the 3 H@ , 8 JD , 12 JD and 16 JD weeks of life all pheasants were weighted and tarsus length, wing length and wingspan were measured. Male chicks appeared to be significantly heavier than females (P#0.01) already in the third week of life. Also their wings were longer and their wingspan attained higher values (P#0.05). Absolute gains of the majority of traits also differed between sexes (being larger in males) in all studied periods. Values of body weight, tarsus length and wingspan noted in the third week of life were significantly correlated with all later measurements. Thus body weight and some biometrical traits of pheasant chicks measured already at the 3 H@ week of life could be applied as predictors of future body weight and size.
