Abstract
Electrophoretic variations in albumin were studied in the blood plasma of the chicken. A synthetic breed mainly originated from White Leghorn and White Cornish X White Plymouth Rock hybrids were used. The starch gel electrophoretic procedure used was that described by LUSH (1964) for chicken egg white proteins.
Three albumin types were observed in the plasma of White Cornish X White Plymouth Rock hybrids. The three types wer ecoded Alb A, Alb AB and Alb B. Alb A was characterized by a distinct zone which was accompanied by two zones, one in front of the mian zone and the other behind. Alb B had the same pattern as Alb A except the zones had different migration rates. The migration rate of the main zone of Alb A coincided with that of the leading zone of Alb B. The migration rate of the main zone in Alb B coincided with that of the tailing zone in Alb A. Alb AB had the two distinct zones and the two faint zones.
The 248 hybrid chicken plasma which were examined included 229 Alb A, 17 Alb AB, and 2 Alb B type. The plasma of 68 White Leghorns were monomorphic and were classified as Alb A.
