Sažetak
The aim of this study was to compare the slaughter dressing and the
dressing of characteristic organs and tissues of six breeds of wildfowl: wild turkey (Meleagris gallopavo), guinea-fowl (Numida meleagris), chukor (Alectoris chucar), Japanese quail (Coturnix coturnix japonica), common pheasant (Phasianus colchicus) and grey partridge (Perdix perdix). For the purpose of the study, in January 2007, 10 birds of each species were slaughtered (5 males and 5 females)and analysed. The birds were bred in equal conditions in the breeding centre of the Veterinary and Pharmaceutical Faculty, University in Brno. The birds were bred in roosts applying equal system of feeding and watering systems and were randomly
selected for the study. Immediately following the selection the birds were weighed, slaughtered and processed in the conventional method, similar to that in chickens intended for slaughter. A special attention was paid to the weight of the trunk, neck, heart, liver, stomach, abdominal fat, breast muscles, drumsticks (with and without skin), upper legs and the muscles of the upper legs and drumsticks. On the ground of the data obtained with respect to the
live weights of the birds, slaughter dressing and the dressing of individual organs and tissue were calculated. The results obtained show that differences in slaughter dressing and the dressing of the investigated organs and tissue between some breeds are significant (P<0,05). The highest slaughter dressing was faund in Japanese quail (71.14 %), slightly lower in guinea fowl (70.62 %), common pheasant (69.74 %), grey partridge (69.09 %) and chukor (68.92 %) and the lowest in wild turkey (67.99 %). Statistically significant differences (P<0.05) in average values were established between quail and turkey, quail and chukor, guinea fowl and turkey and guinea fowl and the chukor. Differences between individual fowl breeds were also considered with respect to indicators of slaughtering processed trunk.
