Sažetak

The aim of this study was to determine the productivity of Croatian breed of hens Hrvatica in free-range raising. Hens aged 20 weeks were housed in 11 family farms, with were two flocks of 10 hens in each. Monitoring production results lasted 32 weeks. All hens were fed complete feed mixtures (15% protein and 11.28 MJ/ME), and they had access to a grass area (10m2/hen). Data on the number and
weight of eggs and feed consumption were collected. The strength of the shell, yolk colour and Hough’s unit values of 10 eggs of each flock in the 10th week of investigation were determined. Cost-benefit analysis was done to calculate the economic indicators of production. The average number of eggs per hen was 130.98 eggs, feed conversion 3.46 kg/kg of egg mass and average egg weight was 51.4 grams.
The strength of the shell was 3.10 kp/cm2, yolk colour at La Roche scale was 11 and the value of Haugh’s unit was 66.02. Total income included amounts received by selling eggs and government incentives amounted to €7674.80, while the variable costs were €2773.10. Contribution to cover all 11 family farms costs was € 4901.70
or € 445.61 /farm. According to the above, we conclude that the hen Hrvatica can be fully recommended for free-range raising on small family farms in Croatia while there are government incentives.
