Sažetak
Zagorje turkey breed is a local Croatian breed with breeding tradition more than five century. Today this breed is in state of renewal and protection. In the year 2009 were 2615 birds and 224 breeders included in herdbook of Zagorje turkey. The aim of this study was to present some morphometric traits of bones femoris, humerus and sternum (weight (W) length (L), circumference (CC) and breadth of corpus (BC) and epihysis proximalis (BP) and epiphisis distalis (BD), sternum breadth). In addition, it was analysed the carcass composition of male and female. The birds (136 birds; 68 ♂ and 68 ♀) were reared in two phases. During the first phase (from 1st day to 8th week of age) the poults were reared indoor under controlled microclimatic conditions and during the second phase (from 8th to 26th week of age) were kept on grassland in outdoor production system. The significant differences (P≤ 0.05) were observed in live weight and carcass weight between the male (6.77 kg and 4.59 kg) and female (3.96 kg and 2.68 kg) while the proportion of body parts (breast, thigh, drumstick, thigh loin and abdominal fat) were not different between male and female. As could be expected male turkey showed higher value of all morphometric traits of femur, humerus and sternum than female. These results contribute to knowledge about characteristics of skeleton and carcass composition of Zagorje turkey because there is not data about these traits.
