Abstract
Description
Evaluation of egg quality characteristics and influencing factors are very important to note. One of the factors that affect the quality of the egg is the breed of chicken. The research objective was to compare some parameters of egg quality between White Leghorn (WL) and Naked Neck chicken. Number of eggs collected were 49 eggs from WL and 59 eggs from Naked Neck. All variable egg quality was measured using an egg multi tester EMT-5200. For egg white grading, it was used the standards of the USDA (grade AA, A, and B). The average of egg weight was significantly (P<0.05) influenced by the breeds. Thickness of eggshell were significantly different (P<0.05) between WL and Naked Neck chicken (0.46±0.05 vs 0.43±0.04 mm). Haugh units (HU) were significantly higher in WL (67.64±9.97) compared with Naked Neck chicken (57.62±11.69). The percentage of the characteristics of the egg white on a WL chicken more on grade A (47.68%) while the Naked Neck chicken on grade B (59.18%). More yolk color WL chicken on score 4 (52.54%) and Naked Neck chicken on score 5 (48.98%). It can be concluded that, egg weight, eggshell thickness, HU, and the percentage of egg white on WL chicken showed superior than Naked Neck chicken.
