Comparative Studies on Physical and Chemical Property of Avian Eggs

SDS-polyacrylamide gel electrophoretograms of egg white of the chicken (White Leghorn, Rhode Island Red and Totenko-a Japanese native breed), quail, golden pheasant, silver pheasant, duck (Khaki Campbell, Pekin and Naki- a Japanese native breed), muscovy duck and pigeon were compared.The egg white proteins were separated into 14 bands (Nos 1-14) in 10% gels. The mobility of the same protein bands in 10% gels were almost same among the species used except pigeon. The density of the band Nos 4, 5, 6, 9, and 14 was higher in Anseriformes species than in Galliformes species. In Columbiformes (pigeon), the bands Nos 1-6 were faint and Nos 7-12 were dense and the mobility of the bands was slower than those of Galliformes and Anseriformes species.In Galliformes species, the density of lysozyme band (No. 2) was the highest in the silver pheasant, the second highest in the chicken, the third highest in the golden pheasant and faint in the quail. In Anseriformes species, the density of lysozyme (No. 2) and ovotransferrin (No. 12) of the muscovy duck was higher than those of the duck.
