- Abstract
Japanese quail embryo thermal manipulation was known as an effective protocol in improving post-hatching growth performance parameters and thermotolerance acquisition which alleviates heat stress during rearing. The current study aimed to evaluate the effects of high incubation temperature protocols (41°C for 3 hours / 3 successive days) during early and late embryogenesis on quail embryo performance. Two hundreds of quail eggs was incubated at 37.7°C and 55% RH as control group. Two thermally treated groups (two hundreds eggs for each) were incubated intermittently at 41°C and 65% RH intermittently (3 hours / day): The early embryonic group was thermally treated during embryonic days (ED 6 - 8), while the late embryonic group was thermally treated during ED 12 -14. These thermal manipulation protocols did not affect embryo development, yolk consumption, hatchability and hatched chick quality.
