Poultry Egg Incubation: Integrating and Optimizing Production Efficiency
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
Due to its central position in the production chain, in-ovo development is influenced by pre-incubation factors that affect the quality of embryonated eggs and incubation conditions themselves, and both may influence egg ...
Effect of temperature on incubation period, embryonic mortality, hatch rate, egg water loss and partridge chick weight (Rhynchotus rufescens)
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2003-05-01)
The aim of this study was to determine the effects of incubation temperature (34.5; 35.5; 36.5; 37.5 and 38.5ºC), on incubation period, embryonic mortality, hatching rate, water loss and chick weight at hatch, using daily ...

Effect of breeder age on eggshell thickness, surface temperature, hatchability and chick weigh
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2012-03-01)
Two experiments were carried out to study the effect of breeder age on incubation parameters (hatchability, eggshell thickness, egg surface temperature and chick weight). In Exp. 1, fertile eggs (30- and 60-wk-old breeders) ...

Incubation and rearing temperature effects on Hsp70 levels and heat stress response in broilers
(Agricultural Inst Canada, 2003-06-01)
Incubation temperature (IT) was changed to evaluate if 6-wk-old birds become more tolerant to heat stress. After 13 d of incubation, 470 eggs were submitted to low (36.8degreesC), normal (37.8degreesC) and high (38.8degreesC) ...
Effects of incubation temperature and relative humidity on embryonic development in eggs of red-winged tinamou (Rhynchotus rufescens)
(2012-01-01)
This study was conducted to assess the effects of incubation temperature (34°C, 36°C and 38°C) and relative humidity (RH, 50% and 60%) on egg weight loss, embryo mortality, hatchability, incubation time and chick weight ...
Effect of High Incubation Temperature on the Blood Parameters of Layer Chicks
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
Adequate environmental temperature control is essential for incubation efficiency. Layer breeder eggs (n=360) were weighed and distributed in a completely randomized experimental design with two treatments, consisting of ...
