Abstract
Applicability of the TOBEC method (electrical conductivity) was tested for the in vivo determination of different egg components and for the separation of eggs with different composition. Altogether 300 hen’s eggs – originated from a 36 weeks old ROSS-308 hybrid parent stock – were measured by TOBEC, and the extreme and average 5-5% – based on the measured values – were chosen for chemical analysis. It was established that the albumen/yolk ratio and the dry matter, crude protein and crude fat content of the eggs are in medium correlation with the E-value/egg weight ratio (r=0.47, -0.58, -0.59 and -0.35 respectively). The albumen/yolk ratio, the dry matter and the crude protein content of the eggs, selected for high and low E-value/egg weight ratio, differed significantly at P<0.05 level. The difference between the average crude fat content of the eggs in the two extreme groups was significant at P<0.10 level.
