Models of the Relationships between Egg Dimension and Egg Quality of Alabio Duck

This research aimed to establish the relationship models between the length and width of Alabio duck (Anas platyrhynchos Borneo) eggs and the weight of eggshells, albumen, and yolk. Data were collected from 500 eggs and were further examined using Pearson’s correlation and regression analysis. The results showed that egg length was positively correlated with eggshell, albumen, and yolk weights (r=0.28, 0.53, 0.52, respectively; P<0.05). These results were lower than the correlation between egg width and eggshell, albumen, and yolk weights (r=0.46, 0.66, 0.46, respectively; P<0.05). Egg length (x1) and egg width (x2) conjointly had a significant relationship with the weight of shell, albumen, and yolk, with a model of y = -2.59 + 0.34x1 + 0.15 x2 (R2=0.23; P<0.05); y = -51.98 + 0.49x1 + 2.06 x2 (R2=0.56; P<0.05); and y = -32.43 + 0.45x1 + 0.63x2 (R2=0.38; P<0.05), respectively. It was concluded that the length and width of Alabio duck eggs offer the potential to estimate albumen and yolk's weight.
