2004
Oblakova, M. (Agricultural Institute, Stara Zagora (Bulgaria)) | Tanchev, S.
Five hundred and sixty gees of the breeds Landen Grey, Local Benkovsky Goose, Hybrid "Bela-1", Wild Wightfront and Sowing Geese were studied. Two types of estherases were established in the blood serum and frequances of alleles and genotypes by the polymorphic system Es-1 were also determinated fined. Four groups were made using the results of 22 parents couple and a hybrid analysis was done with the enzime Es-1 from 90 of their offsprings. A difference in the speed of Es-1 migration in domestic and wild gees, was established as higher electromobility was found in the wild ones. Following the tissue esterasis, in the heart muscle was fixed one type; Es-10 and in the liver respectively five types: two monomorphic Es-5, and three polymorphic - Es-6, Es-7, Es-8, determined by two-alleles genes.
