ABSTRACT The objective of this study was to evaluate a technique for quantifying eggshell conductance using shell fragments from hatched eggs. Additional objectives were to calculate the correlation between eggshell conductance, porosity, and thickness and correlate these parameters with incubation data. The study design was fully randomized in a 3 × 3 factorial scheme (three egg regions – large end, equator, and narrow end – and three ages of broiler breeders – 29, 35, and 59 weeks). A total of […]
