| Summary: | Poultry farming, as an essential pillar in the agro industrial sector, faces a range of challenges
that bring together genetics, developmental biology and environmental factors. At the center of
these challenges is the impact of incubation temperature on sex determination and phenotypic
development of birds, a topic of high scientific and practical interest. This literature review
focuses specifically on this aspect, considering its relevance in the framework of modern poultry
farming, determining an incubation temperature that can significantly influence chick quality,
viability and the sex ratio at birth, phenotypic characteristics. key for poultry production. The
most important modifiable environmental factor in incubation is temperature; but the strength of
this influence depends on the time frame used and the duration of changes in incubation
temperature during embryogenesis. This phenomenon is particularly relevant in birds, where
females have a heterogametic sexual chromosome configuration and males have a homogametic
sexual chromosome configuration. Research has revealed that short-term thermal stimulation,
applied in the final days of incubation, appears to increase the proportion of male chicks, a
finding that challenges traditional understanding of sex determination in birds. |
