dc.description.abstractWith the aim to determine the influence of Lohman Brown laying hen hybrids age and eggs weight on some characteristics of eggs quality-structure and their correlation relationship, experiment was conducted on two egg samples (160 + 160 = 320 eggs) derived from 20 weeks (the oviposition intensity - 18.29%) and 28 weeks (maximum oviposition - 95.69%) old hens. With laying hens aging there was statistically significant increase (P < 0.001) of average eggs weight from 46.15 up to 59.89 g. Similarly, the absolute proportion of shell, yolk and egg albumen in weight was significantly higher (P < 0.001) at 28 weeks old laying hens than in 20 weeks old laying hens. Percentage share of raw shell in eggs weight was almost similar in both age hens’ groups (13.27 - 13.41%); yolk percentage share was significantly higher (P < 0.001) at older hens (25.90%) than at younger hens (23.60%), while the albumen percentage share in the egg weight situation was reversed, i.e. younger hens (lighter eggs) had a higher albumen percentage share (63.13%) from hens 28 weeks old (60.69%) (P < 0.001). At young laying hens (lighter eggs) phenotypic correlation coefficient between egg weight and crude shells percentage share was -0.425 (P < 0.001), the yolk percentage share -0.093 (P > 0.05) and percentage of albumen share 0.086 (P > 0.05). At 28 weeks old laying hens (heavier eggs) correlation coefficient between egg weight and percentage share of shell, yolk and albumen were: raw shell -0.142 (P > 0.05), egg yolk -0.776 (P < 0.001) and 0.534 egg albumens (P < 0.001).
