Quail development in <i>in ovo</i> and <i>ex ovo</i> conditions: Preincubation influences stress proteins and antioxidants.

ABSTRACT: Extreme temperatures, whether excessively high or low, are critical environmental stressors for organisms, profoundly impacting cellular metabolism and homeostasis. The presented study addresses the effects of varying incubation conditions on the expression of key stress-related genes (HSP70, HSP90, and SOD1) during quail development. Quail eggs were incubated using three distinct methods: standard incubation at 38.2°C and preincubation at either 22°C or 30°C in both in ovo and ex ovo conditions. Results revealed a distinctive contrast in survival rates: embryos cultured ex ovo showed significantly lower viability (26.41 %) compared to the in ovo method (87.66 %). Among ex ovo groups, preincubation at 30°C yielded the highest survival rate (43.48 %), high
