Celem pracy było określenie przy pomocy pomiarów termowizyjnych tempa oddawania ciepła przez jajo kurze z rozwijającym się zarodkiem. Stwierdzono, że temperatura powierzchni skorupy jaja (EST) wzrasta w kolejnych etapach embriogenezy i może przewyższać temperaturę powietrza w inkubatorze. Niewielki spadek EST w 19. dobie inkubacji jaj umieszczonych w temperaturze pokojowej przez okres 15 minut, wskazuje na wykształcenie przez zarodek na tym etapie rozwoju zdolności ograniczonej termoregulacji.

The aim of this study was to investigate the rate of heat transfer by a hen's egg with a developing embryo with use of infrared measurements. The study was conducted on 600 eggs for hatching chicken Ross 308 broiler line. The eggs were incubated in the setter S576 Petersime ® at the air temperature (T) equal to 37.8°C and relative humidity (RH) in the range 49-50%. Thermographic measurements of the eggshell surface temperature (EST) were taken with use of a thermal imaging camera ThermoVision A20 of a detector resolution 120x160 pixels. For statistical analysis of each egg there were used the EST highest values measured. Subsequent sessions were measured in the following days of incubation: E1, E3, E4, E7, E8, E9, E11, E12, E13, E16 and E19. Trays with eggs were removed from the incubator and placed at T = 22.4°C and RH = 75%, and recording of EST was performed: 1) immediately after removing the eggs from the incubator, 2) after 15 min, 3) after 30 min. It was found that the EST increased during the subsequent stages of embryogenesis. Before the start of the hatching process the temperature value may exceed the air temperature in the incubator by about 2 °C. The increase in the surface temperature of the egg shell is particularly intense from the 10th day of embryogenesis, reflecting the intensification of metabolism of the embryo. The slight decrease in the crust surface temperature of eggs placed at the room temperature for 15 minutes in the 19th day of incubation, compared to earlier stages of embryogenesis, shows that the embryo at this stage of development has the limited ability of thermoregulation.
