STUDY OF THE GENETIC STRUCTURE OF THE POPULATIONS OF SHEEP AND POULTRY ON THE BASIS OF IMMUNOGENETIC MARKERS

In this work the results of the genofund structure and the possibility of using of immunogenetic markers, fi-Lg, Ov, Cn etc in selection are given. For this reason the breed, lines, hybrids of various kinds of sheeps and poultry were studied on the basis of such exponents as frequency of alleles and genotypes, genetic similarity of population, genetic balance, the structure of polymorphic system of blood albumen and milk of sheep and polymorphic blood systems and albumen of hen eggs. At sheeps was founded polymorphism lactoproteins aS1Cn, fiCn, kCn, fiLg. In the locus aS1Cn, there are three alleles which are most typilcal for the type aS1CnB -0,9354. In the locus fiCn there are two alleles which have been discovered in the type fiCn with the frequency of0,5988. The loci of the genes kCn and fiLg are characterized by two alleles which are most often found in the type kCn 0,7581 and fiLgA0,6776. In our research applied on sheep, the polymorphism of the aS1Cn, fiCn, kCn, fiLg milk proteins have been established At hens crosses hybrids Albo-70, Roso SL 2000 and Roso 93 in the systems of hemoglobin, transferrins and ceruloplasmins were characterized by the presence of two alleles: A and B. The frequency of occurrence of alleles is different: in the system of hemoglobin the allel HbA has a higher frequency -0,9000-0,9875. In the system of transferrins the allel Tf is found more often-0,7625-0,7879. The advantage of allel Cp4 has been proved in the locus of ceruloplasmins as well. Thus the ascertained polymorphism of the milk proteins may be widely used as a biochemical test to evaluate the state of the breed gene pool as for predicting the productive qualities of these animals
