O estudo sugeriu que a linhagem teve efeito significativo sobre a condiÃ§Ã£o da plumagem e sobre alguns aspectos comportamentais, particularmente, aqueles relacionados ao uso do banho de areia.Įffect of Î³-Aminobutyric Acid-producing Strain on Laying Performance, Egg Quality and Serum Enzyme Activity in Hy-Line Brown Hens under Heat Stressįull Text Available Heat-stress remains a costly issue for animal production, especially for poultry as they lack sweat glands, and alleviating heat-stress is necessary for ensuring animal production in hot environment. Em ambas as linhagens, Isa Brown e Hy line W98, o modelo de gaiola estudado foi apropriado em termos de desempenho produtivo. 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.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. Based on productive parameters, the model of furnished cages studied is suitable for both, Isa Brown and Hy line hens.
