AB  - Egg producers in the EU had more than a decade to adapt to Directive 1999/74/EC which prohibits keeping laying hens in battery cages after 2012. Meanwhile, numerous studies have been conducted in order to assess the socio-economic implications of this ban and to evaluate consumers' willingness to support improvement in layer welfare by paying a higher price for eggs produced in alternative systems. The adoption of such regulations in Serbia with the implementation timeframe of less than two years, and without any assessment of consumers' willingness to pay a higher price for eggs from alternative systems, places the burden of animal welfare on producers. Considering the overall difficult financial situation of egg producers, this poses a risk that a large number of egg producers in Serbia will leave the sector after 2012.

AB  - The aim of this work was to evaluate production traits, egg quality parameters and welfare indicators of two strains of layers (Hisex White and Hy Line Brown) kept in different housing systems. In each housing system both strains of layers were housed and that made 6 treatments in 2 x 3 factorial design (2 genotypes x 3 cage types). A) conventional battery-cages with 5 hens per cage providing 500 cm(2) of floor space per bird (n = 180 (90 white and 90 brown layers), 36 cages in total, 5 hens/cage, floor space = 500 cm(2)/hen); 13) enlarged battery-cages with 5 hens per cage providing 650 cm(2) of floor space per bird (n = 120 (60 white and 60 brown layers), 24 cages in total, 5 hens/cage, floor space = 650 cm(2)/hen); C) enriched cages with 60 hens per compartment providing 750 cm(2) of floor space per bird (n = 360 (180 white and 180 brown layers), 6 cages in total, 60 hens/cage, floor space = 750 cm(2)/hen). Examination of egg quality parameters was carried out in 8 lour-week periods, starting from 32 weeks of rage on the random sample of 30 eegs per treatment. Condition of feathers ware evaluated by scoring system at the end of the production cycle (70 weeks of age), and at the same time duration of tonic immobility was measured. The results showed that white layers in conventional cages achieved the best production results. The highest number of eges was achieved with white layers in B and the lowest with the brown layers in C. White layers laid considerably more eggs compared to brown layers and had the best shell quality in all of the three housing systems. The birds in enriched cages laid significantly less eggs compared to other two cage types. The worst feather condition at the end of the production cycle was noticed in conventional cages (A) in both hybrids. Generally, brown layers suffered from more severe feather damage in all cage types compared to the white layers. The results showed a significant effect of cage type (p (lt) 0.01) and hybrid type (p (lt) 0.05) on duration of tonic immobility (TI) indicating that fearfulness of the birds was highly affected by, housing system and genotype. Birds from both genotypes kept in conventional cages showed a shorter duration of TI than the birds kept in enriched cages and the white layers showed longer duration of TI than the brown layers.
