Sažetak

This research aimed to determine the meat production indicators and carcass traits of Posavska crested hen, which is the Croatian indigenous chicken breed. The research was carried out on five strains of the Posavska crested hen breed: yellow vetch, vetch, red colourful, light gray, and golden brown. Feeding was ad libitum for the whole time, adapted to the age of the chickens from a nutritional point of view. Separation by sex was carried out at the age of four weeks, while slaughter of roosters and determination of carcass traits was done at the age of 18 weeks. The highest average body weight was achieved by roosters of light gray and yellow vetch strain (3542.63 and 3430.38 g, respectively) and light gray pullets (2562 g) at the age of 18 weeks. The lowest feed conversion ratio was achieved by the light gray strain (2.39) at four weeks of age, and by the the roosters of the light gray strain (4.07) and pullets of the light gray and golden brown strain (4.08) at 18 weeks of age. The average dressing percentage was 71.54%, while the highest average dressing percentage was established in the red colourful strain (72.48%). Regarding the proportion of individual parts of the carcass, a significant (P < 0.05) influence of the strain can be seen in the proportion of drumsticks in the carcass, the proportion of which was the highest in the yellow vetch strain (18.69%). A significant influence of the strain was also found regarding L* (P < 0.01) and a* (P < 0.05) skin color indicators. Considering the established differences between the strains, it is necessary to carry out further selection and work on the uniformity of the breed.
