Cím:Predictability of Egg Content in Hen's Eggs by Means of Cross Sectional Image Analysis / Tamás Donkó, Miklós Emri, Gábor Opposits, Gábor Milisits, Zoltán Sütő, Attila Orbán, Imre Repa
Megjegyzések:The present study was designed to determine the in vivo predictability of egg content in hen's eggs by means of computer tomography (CT). The experiment was carried out with altogether 120 eggs, which were originated from a 36 weeks old TETRA-H parent stock. During the CT measurements eggs were placed in egg holders (10 eggs) thus two eggs were scanned simultaneously. Following scanning parameters were set in: 110 kV ? 40 mAs, spiral mode, pitch 1, FoV 110 mm. In all cases eggs were scanned using overlapping 3 mm slice thickness on a Siemens Somatom Emotion 6 multislice CT scanner. On the CT images obtained the volume of the albumen, yolk and shell was determined by a self-developed egg-separation and segmentation software. After the CT measurements eggs were broken and their yolk, albumen and shell weight were measured. Between the CT predicted volumes and the measured weights Pearson correlations were calculated. The highest correlation (r=0.90) was found between the CT predicted albumen volume and the measured albumen weight. In the case of the yolk and shell the correlation coefficients were 0.793 and 0.713, respectively. Based on these results it was concluded that the accuracy of prediction seems to be precise enough in the case of the albumen, but its improvement is necessary in the case of the yolk and shell. Possible ways for improving the accuracy of prediction could be the use of another algorithm in the egg-segmentation software and the optimization of settings of the CT examination.

Cím:Application of computed tomography to assess the effect of egg yolk ratio on body composition in chickens of different genotype and gender at hatch and during the rearing period / G. Milisits, T. Donkó, A. Dalle Zotte, A. Sartori, E. Szentirmai, M. Emri, G. Opposits, A. Orbán, O. Pőcze, I. Repa, Z. Sütő
Megjegyzések:Computed tomography was used for the in vivo determination of yolk ratio in 7000 domestic hen eggs, originated from two markedly different genotypes, in order to examine the effect of egg yolk ratio, gender and genotype on the development of hatched chicks. 2. Eggs with extremely low, average and extremely high yolk ratio were chosen for further investigation (n=350 in each group in both genotypes). After incubating the selected eggs, hatched birds were reared and slaughtered at 11 weeks of age. 3. The yolk ratio of eggs significantly affected the body composition of the chickens at hatching and during rearing to 8-9 weeks of age. 4. Chickens of a genotype selected partly for weight gain had significantly higher live weight from hatching to the end of the rearing period and had better slaughter characteristics than those of the dual purpose TETRA-H genotype. 5. At hatching, only the dry matter content of the body was affected by the gender of the birds. The effect of gender on the live weight and body composition of chickens was evident from the 5th week of age to the time of slaughter. 6. It was concluded that eggs with a low yolk ratio were most beneficial for broiler production, because chickens hatched from these eggs had the highest slaughter weight and muscle index and the lowest fat index for their body mass.
