Résumé:
The main objective of This Work is to study the characteristics and the internal and external quality of the eggs and the morpho-weight parameters to compare between the eggs of local hens (LH) and those of selected strains (SS).
Our study shows that SS eggs exhibited a significant superiority for egg weight which was 61.61 ± 4.26 against 55.18 ± 7.85 for SS and PL eggs respectively. The recorded lengths are 5.49 ± 0.58 and 5.61 ± 0.39 for PL and SS respectively with widths of 4.25 ± 0.39 and 4.26 ± 0.29 for PL and SS respectively d where a significant difference was recorded.
We also recorded a significant difference for the weight of the shell (7.96 ± 0.77 and 7.11 ± 0.82 for SS and PL respectively) the weight of the albumen was 36.37 ± 2.94 more important compared to the eggs PL 29.96 ± 8.42. on the other hand the local population gives eggs with higher yolk contents 17.31 ± 2.93 and 18.22 ± 2.84 for PL and SS respectively
Our results show that there is a highly significant difference for the pH of the yolk between the two populations studied 6.15 ± 0.23 in SS while that of PL was less with a value of 6.01 ± 0.24 and the pH of the white 8.96 ± 0.31 and 8.53 ±0.28 for SS and PL respectively
A significant difference was found for the MM content (0.80 ± 0.082 and 0.12 ±0.11 for PL and SS respectively) while the other parameters MO (27.73 ± 17.81 and 26.47 ± 16.67 respectively), MS (29.75 ± 18.92 and 28.15 ± 17.51 for SS and PL respectively) and total lipid contents (24.25g and 23.52g for SS and PL eggs respectively) did not show a difference
