Avaliação de programas de iluminação sobre o desempenho zootécnico de poedeiras leves

Abstract: RESUMOFoi avaliado o efeito de programas de iluminação sobre o desempenho zootécnico de poedeiras leves ao final de produção, em experimento realizado no Departamento de Zootecnia da Universidade Federal de Lavras -UFLA. Foram testados um programa de iluminação intermitente e outro com apenas iluminação natural, em dias de luminosidade crescente, em comparação com um programa contínuo com a utilização de 288 poedeiras leves da linhagem Leghorn branca. As aves foram alojadas em galpão dividido em 3 ambientes, p… Show more

“…Evaluating the effect of intermittent lighting programs on layer performance, Morris (1973) concluded that they can be applied in commercial egg production, and should be further explored. Freitas et al (2005) compared the effects of an intermittent lighting program, natural lighting on days of increasing lighting, and a continuous lighting program on the performance of layers at the end of the laying cycle. The authors concluded that the intermittent lighting program or only natural lighting on days of increasing lighting can be applied in opensided houses to maintain performance.…”

“…The artificial light is routinely used in lighting systems for commercial laying hens which may delay or accelerate sexual maturity, stimulate egg laying and improve weight gain in laying poultry and arrays (Freitas et al, 2005;Araujo et al, 2011). The delay in the beginning of the egg production through light control determines a better quality of shell, less eggs with two yolks or deformed eggs, and lower mortality due to prolapse (Araujo et al, 2011).…”

“…Em aves de postura, já é bastante conhecida a função da luz com o objetivo de aumentar o fotoperíodo e estimular a produção de ovos (FREITAS, 2009). Entretanto, pesquisas sobre os efeitos da luz sobre as funções reprodutivas do macho são limitadas (MACIEL et al, 2009).…”
