Comparative analysis of the external and internal egg quality in different pure chicken breeds

The present study was conducted to evaluate some parameters of external and internal egg quality of some pure dual chicken breeds.  A total of 500 eggs (100 eggs from each breed) were collected to study for egg (weight, shape index), albumen (weight, percentage), yolk (weight, percentage) and shell (weight, percentage, thickness, strength) quality. The eggs were analysed in the laboratory of Department of Poultry Science and Small Animal Husbandry of Slovak University of Agriculture in Nitra. The results showed that the egg weight and egg length of New Hampshire were significantly higher (P 0.05). Differences in albumen weight, albumen percentage, yolk weight and yolk percentage of tested dual chicken breeds were statistically no significant (P>0.05). Albumen height was significantly higher (P 0.05) in egg shell thickness and strength.
