Evaluation of the solar contribution in a hybrid incubator of red-legged partridge (Alectoris rufa) eggs CIGR Journal
Garcia-Hierro, Javier.
Solar thermal energy has been widely employed by the agro food industry with the objectives of reducing conventional sources of energy and achieving a reduction in greenhouse gas emissions. The focus of this manuscript is to evaluate a medium scale commercial incubator (for 9072 red-legged partridge eggs) supported with solar thermal energy under detailed monitoring. In this sense, an evacuated solar collector with an absorbing area of 0.99 m2 and 163 L of water accumulation (with an auxiliary 80-L water tank) was coupled to the original emergency cooling system of the incubator. The hybrid system, using an automated control system, shows higher thermal stability (std=0.12ºC) than the standard control system of the incubator (std=0.18ºC). The area of the...

Prospectives of monitoring biological activity in a red-legged partridge incubator with a carbon dioxide probe CIGR Journal
Garcia-Hierro, Javier; Barreiro, Pilar; Moya-Gonzalez, Adolfo; Robla, Jose Ignacio.
This study focuses on the relationship between CO2 production and the ultimate hatchability of the incubation. A total amount of 43316 eggs of red-legged partridge (Alectoris rufa) were supervised during five actual incubations: three in 2012 and two in 2013. The CO2 concentration inside the incubator was monitored over a 20-day period, showing sigmoidal growth from ambient level (428 ppm) up to 1700 ppm in the incubation with the highest hatchability. Two sigmoid growth models (logistic and Gompertz) were used to describe the CO2 production by the eggs, with the result that the logistic model was a slightly better fit (r2=0.976 compared to r2=0.9746 for Gompertz). A coefficient of determination of 0.997 between the final CO2 estimation (ppm) using the...
