Condições ambientais em galpão convencional telado para galinhas poedeiras hyline W-36

Abstract: RESUMO:Devido às ocorrências dos vírus de influenza aviária (H5N1 e H7N2), estudos relacionados à biosseguridade têm-se intensificado, e uma das soluções discutidas é o uso de tela para cercar completamente o perímetro dos galpões, visando a evitar o contato das galinhas poedeiras alojadas com outras aves. Desta forma, o presente trabalho teve como objetivo avaliar e comparar a utilização de tela cercando o perímetro de galpões convencionais de poedeiras, sobre o ambiente acústico e aéreo no interior da instal… Show more

“…Average noise levels inside commercial laying hen housing have been reported as 59.7-63.4 dB (Lourenconi et al, 2015).The maximum sound pressure level recorded for flocks of pullets and hens housed in barn or free-range systems was 72 dB, with an average level of 58.3 dB (with sound levels in some flocks showing wide variation levels during the period of measurement (Gilani et al, 2013)). The probability of severe feather pecking in adult flocks was increased when pullets had been reared in environments with more variable sound levels (Gilani et al, 2013).…”

“…Enquanto em ambientes internos de instalações para animais, o limite máximo recomendado de CO2 é de 3000 ppm (WATHES, 1999). Várias pesquisas já foram conduzidas na avicultura (LIMA et al, 2014;LOURENÇONI et al, 2015;MENEGALI et al, 2009;OLIVEIRA, PAULO ARMANDO V. DE;ANGNES;COLDBELLA, 2020;VIGODERIS et al, 2010) visando quantificar o CO2 e relacionar a sua concentração com a condição térmica da instalação (Tabela 1).…”
