Abstract:
This Study Was Undertaken To Compare Some of Qualitative and Chemical Characteristics and the Electrophoresis of eggs of white and grey Iraqi geese. Birds were bred at private farm( Babel province) For the Period from 1st oct.2016 to 2nd Feb. 2017. A total of 40 females geese aged 2 years (at their second eggs production season) (20 birds white color and 20 birds gray color) were used. Eggs were collected daily from each group. Birds were kept in closed barns with swimming pool in side. The aim of this study was to estimate some qualities and chemical traits of eggs from different group(White and Gray Geese ). Fatty and amino acids were also estimated Electrophoresis of egg white portions was also compared the results revealed the following : 1 - There was a significant increase in means of egg Weight, yolk and egg white of white geese (143.40 , 52.94 and 62.89m respectively) the grey geese egg shell weight was height than that of white geese.2 - There were significant differences in egg shape index and in Haugh unit of grey geese (68.27 and 100.90 respectively) in comparison with those of white geese.3 - Grey geeses eggs showed higher (p≤0.05) moisture percentage (69.10%). However, Yolk white geese egg showed higher protein and fat percentages (16.96, 35.64) % respectively in comparison with those of grey geese eggs (14.19, 32.97) % respectively.4 - pH of eggs white of white geese (9.12) was significantly higher than that of grey geese, whereas, Yolk showed higher cholesterol level (4.42 mg/gm).5 - Unsaturated fatty acids percentage (mono and poly bonds) of egg yolk were high in both group geese (66.11 and 63.78)% whereas, saturated fatty acids percentages of white and grey geese were 32.94 and 32.22% respectively.6 - Egg white of grey geese revealed significantly(p≤0.05) higher percentage of Arginine and alanine of both white and yolk (26.98 and 17.18% respectively). There were no significant differences in amino acids percentages of egg yolk of both groups.7 - There was genetic Poly morphism in albumin and transferrin of White and grey geese eggs proteins. As well as, there was genetic variation in the two proteins of Iraqi geese.
