چکیده
The objective of this study was to elucidate the optimum protocol timing thermal manipulation (TM) during embryogenesis, which underline genetic improvement muscle thermotolerance acquisition. For present study, 1,440 fertile eggs were divided randomly and equally into control (37.8 °C with 56% relative humidity) four thermally manipulated groups (TM1, TM2, TM3, TM4) subjected 39 for 18 h 65% humidity daily different embryonic periods. Then, at day 35 post-hatch, all [...]

Effects of thermal manipulation during early and late embryogenesis on thermotolerance and breast muscle characteristics in broiler chickens.
Genetic selection has significantly improved the muscle development of fast-growing broiler chickens in the last 50 yr. However, improvement in muscle growth has coincided with relatively poor development of visceral systems, resulting in impaired ability to cope with high environmental temperatures. The aim of this study was to elucidate the effects of thermal manipulation (TM) during differen...
