Abstract

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.<br>Durante um ciclo completo de postura foram avaliados o comportamento e o desempenho de duas linhagens de poedeiras comerciais, 180 ISA Brown e 120 Hy line W98, alojadas com 17 semanas de idade em gaiolas enriquecidas com ninho, poleiros, banho de areia e dispositivos de desgaste de unhas. Em ambas as linhagens, Isa Brown e Hy line W98, o modelo de gaiola estudado foi apropriado em termos de desempenho produtivo. O estudo sugeriu que a linhagem teve efeito significativo sobre a condição da plumagem e sobre alguns aspectos comportamentais, particularmente, aqueles relacionados ao uso do banho de areia
