Abstract:

This study was conducted to compare the quality of eggs reproduced by different breeds geese at the same feeding and management. 50 geese eggs each breeds of Zhedong White Geese (65 weeks of age), Sichuan White Geese (76 weeks of age), Huoyan Geese (66 weeks of age) were randomly selected to determine their indicators of physical and chemical properties so as to compare their difference of eggs quality. The results showed that there were no significant differences (P>0.05) between three breeds in egg specific density, yolk weight, eggshells proportion, crude protein, crude ash and eggshells’ calcium and phosphorus. The Zhedong White Geese’s egg weight, eggshell strength, eggshell thickness, albumen height, haugh unit, yolk color, protein weight, protein proportion, eggshell weight, index were higher than the Sichuan white geese’s and Huoyan Geese’s (P<0.05 or P<0.01); Huoyan Geese’s egg shape index, eggshell color, yolk proportion, and crude fat content were higher than Zhedong White Geese and Sichuan White Geese (P<0.05 or P<0.01); Many indexes of Sichuan white geese were between Zhedong White Geese and Huoyan Geese. Different varieties of egg quality difference for egg quality improvement provided very good material, and for the people in daily life and provided theoretical basis for rational consumption of eggs.
