Efeito da manipulação térmica durante a incubação sobre as variáveis hematológicas, bioquímica sérica e morfometria da bolsa cloacal de codornas japonesas submetidas ao estresse crônico por calor

Abstract: RESUMO Objetivou-se avaliar os efeitos da manipulação da temperatura de incubação sobre a resposta imune de codornas desafiadas termicamente após eclosão. Para isso, foram utilizados 540 ovos, distribuídos em três incubadoras, com temperatura de 37,8°C e umidade de 60%. A partir do sexto dia de incubação até a eclosão, as temperaturas foram ajustadas em 37,8°C (padrão), 38,5°C (intermediária) e 39,5°C (alta). Após a eclosão as codornas foram pesadas e distribuídas, em delineamento inteiramente ao acaso, com tr… Show more

“…Another recent study on quail found that intermittent TM (+1.7°C, 12 h/d) during ED0‐13 improved thermotolerance during heat challenge (36°C for 7 h) at 35 days of age (Vitorino Carvalho et al, 2020). Similar to chicken but not identical, quails physiologically cope with the heat stress, with a modification of several metabolic and haematologic parameters, including an elevation in plasma corticosterone concentration and a reduction in plasma thyroid hormone levels (Abdel‐Fattah, 2019; El‐Daly et al, 2013; Porto & Fontenele‐Neto, 2020; Vitorino Carvalho et al, 2020). Correspondingly, the surface temperature of the shank was decreased, suggesting a modulation of the blood flow to sustain the interior temperature.…”
