Exploration of a novel indicator for duck egg quality (yolk weight-to-albumen height ratio): Its impact on egg quality and serum parameters, and correlation analysis.

ABSTRACT: This study introduced a novel indicator of duck egg quality - the yolk weight to albumen height ratio (YAR) - and investigated its relationships with egg quality traits, serum biochemical indices, and antioxidant parameters. A total of 1,215 eggs were collected from 450 Shanma ducks (43 weeks old) over three consecutive days. Based on egg quality results, 60 ducks with the highest YAR (HYAR group) and 60 ducks with the lowest YAR (LYAR group) were selected for comparative analysis. Correlation analysis showed that YAR was positively correlate with YW (r = 0.61, P < 0.01) and negatively correlated with AH (r = -0.79, P < 0.01) and HU (r = -0.84, P < 0.01). The HYAR group displayed an altered serum metabolite profile, characterized by elevated total cholesterol (TC), triglycerides (TG), low
