Weight and egg quality correlation relationship on different age laying hens
Апстракт
With 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 lt 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 lt 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 lt 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 eg...gs) had a higher albumen percentage share (63.13%) from hens 28 weeks old (60.69%) (P lt 0.001). At young laying hens (lighter eggs) phenotypic correlation coefficient between egg weight and crude shells percentage share was -0.425 (P lt 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 lt 0.001) and 0.534 egg albumens (P lt 0.001).
