| This study was carried out throughout a laying period to compare the behaviour and performance of two groups of commercial layers, 180 ISA Brown and 120 Hy line W98, housed at 17 weeks of age in furnished cages with a nest box, perches, dust-bath, and claw shortening device. Based on productive parameters, the model of furnished cages studied is suitable for both, Isa Brown and Hy line hens. The study suggested that strain has a significant effect on feather condition and on some behavioural displays, particularly those related to the use of a dust-bath. |

| The influences of floor and cage-rearing on behavioural adaptation to furnished cages were investigated in laying hens. Two groups of 180 Isa Brown commercial layer pullets were reared in cages (CR) or floor pens (FR) and transferred to furnished cages, where their behavioural adaptation was observed throughout the laying period (18-78 wks of age). At 17 weeks of age, hens were placed in one of the 36 furnished cages with 10 birds in each cage, each containing a nest box, perches, a dust bath, and abrasive strips. At 50 and 54 weeks of age, direct visual observation and video recording were used to assess hens behaviour. From 21 weeks of age, the dust-bath activities of leg-banded hens in eight cages per treatment were recorded. The amount of time spent... |
