“…More recent studies have shown that a gradual increase in CO 2 levels up to 1.5% in the first 10 days of incubation enhanced embryo growth, stimulated early hatching and increased hatchability of chicken or turkey eggs (Gildersleeve and Boeschen, 1983;Hogg, 1997;De Smit et al, 2006;Tona et al, 2006). Saddler et al (1954) reported that 4% CO 2 stimulated embryo growth by as much as 20% in the first 48 hours of incubation.…”

Embryonic development is a dynamic process that requires a fine balance between several factors in order to achieve an optimum hatchability and chick quality. These factors include the background of the embryo, such as genetic line of the breeders, the age of the breeder, egg weight, and factors related to the environment in which the egg is stored and incubated, such as temperature, humidity, gas levels and altitude. Gas exchanges are of fundamental importance for embryonic development during incubation and may affect the livability of the embryo. This paper reviews the roles of the gaseous environment (i.e. O 2 and CO 2 ) around hatching eggs during storage and during incubation and the effect it might have on the survival of the developing embryos and the chicks that hatch. The state of the art on the different attempts to establish the optimum requirements of different gases that promote the optimal developmental trajectories at different periods during incubation is presented. The roles and consequences of different levels of O 2 and CO 2 during storage and incubation on hatchability, incubation duration, hatching process, embryo growth, embryo mortality, organ development and morphology, metabolism, blood acid-base balance, chick quality and chick post-hatch growth are reviewed.

“…However, other studies showed that the gradual increase of CO 2 concentration until day 10 of incubation promoted embryonic growth, reduced incubation time, increased hatchability (Gildersleeve et al, 1983;Bruggeman et al, 2008), and improved chick quality (Tona et al, 2007;, 2008. These results were associated with the development of the circulatory system and increased production of red blood cells, allowing greater O 2 uptake and energy conservation (Tazawa et al, 2002;Decuypere et al, 2006;Habermann et al, 2008;Verhoelst et al, 2011).…”

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 hatchability and chick quality, as well as bird survival, growth performance, and phenotype in the field. The evolution of the incubation process over the years is characterized by significant scientific and technological development. Presently, the main current focuses of research are the manipulation of thermal incubation conditions, eggshell temperature, and the integrated effects of factors that influence incubation. In this context, one of the questions that needs to be asked is how effective are the current physical conditions of incubation to promote greater hatchability and better quality chicks, and higher survival and better performance in the field under adverse conditions or not. What are the new and future prospects for incubation? The purpose of this paper was to review the role of the physical agents of incubation, such as temperature, relative humidity, O 2 and CO 2 concentration, and egg turning and position from an integrated perspective, considering egg incubation as the transitional link between egg and poultry production.

Abstract1. Previous research has reported that chicken embryos develop a functionary auditory system during incubation and that prenatal sound may play an important role in embryo development and alter the hatch time. In this study the effects of prenatal auditory stimulation on hatch process, hatch performance, the development of embryo and blood parameters were investigated.2. Four batches of Ross 308 broiler breeder eggs were incubated either in control or soundstimulated groups. Sound-stimulated embryos were exposed to a discontinuous sound of species-specific calls by means of a speaker at 72dB for 16 hours a day: maternal calls from day 10 to day 19 of incubation time and embryo/chick calls from day 19 until hatching. The species-specific sound was excluded in the control group.3. The onset of hatch (IP) was delayed (P=0.05) in the sound-stimulated group compared to controls. This was also supported by comparison of the exact hatching time of individual focal chicks within the two groups. However, the sound-stimulated embryos had a lower hatchability than the control group, mainly due to significant increased numbers of late deaths (P<0.01). The embryos exhibited a similar growth pattern between the sound-stimulated group and the control group. Although sound exposure decreased body weight at day 16, no consistent effect of sound on body weight at incubation stage was observed. Species-specific sound stimulation also had no impact on chick quality, blood values and plasma corticosterone concentrations during hatch.
