ABSTRACT This study examined the impact of a 37.5 °C temperature on chick embryos during the hatching period (18-21 days of incubation) and its subsequent effect on hatchery results and the thermotolerance of broiler chicks from 28-40 days of rearing. For hatchery results, the study involved 16 trays per treatment. For performance, the study involved 360 broiler chicks from two distinct hatching temperature conditions: a control group (36.5 °C and 65% relative humidity (RH)) and a thermal manipulation group (37.5 […]

This study was run to evaluate the physiological response and expression of hepatic and brain Hsp70, of 20 Naked neck (Na/na) and Hubbard-Petersen broiler chicks (2 to 5 days of age), exposed or not to 36-37°C. The trial was conducted during four days and the birds were exposed to high temperature during 5 hours. Liver and brain tissue samples were collected at the end of the stress period and analyzed for Western Blotting for determination of Hsp70 level. No association […]
