For that, the quail hens were fed with three diets related to the methionine supplementation: methionine-deficient diet (Md); diet supplemented with the recommended methionine level (Met1); and diet supplemented with methionine above the recommended level (Met2). Their chicks were identified, weighed, and housed according to the maternal diet group from 1 to 14 d of age. On 15 d of age, chicks were weighed and divided into two groups: thermoneutral ambient (constant temperature of 23 °C) and intermittent heat stress ambient (daily exposure to 34Journal of animal scienceEffects of maternal methionine supplementation on the response of Japanese quail (Coturnix coturnix japonica) chicks to heat stress.PMC10103070001407669/2016-7de Souza Khatlab APereira AMFEGasparino EFernandes RPMDel Vesco APBarbosa LTLamont SJSantana TPfalseEffects of maternal methionine supplementation on the response of Japanese quail (Coturnix coturnix japonica) chicks to heat stress.This study investigated the hypothesis that methionine supplementation of Japanese quail (Coturnix coturnix japonica) hens can reduce the effects of oxidative stress and improve the performance of the offspring exposed to heat stress during growth.
