Summary: For successful breeding and selection of domestic animals it is necessary to know the genetic structure of breeds and genotypes. By carrying out breeding programmes specific animals, lines and families are protected. There is a danger of inbreeding and genetic drifting as well as the loss of some genes. This is particulary marked in small populations of endangered breeds (Istrian cattle, Buša, Ruda sheep, Turopoljska pig and others). Observing the genetic structure of herds is carried out by applying indirect methods of gene frequency analysis of individual polymorphic loci and blood gruops. Within the proposed five year project the genetic structure of breeds of cattle and endangered sheep breeds in Croatia are investigated. This is a direct contribution to getting acquainted with the purity of a breed, the level of kinship and relationship and the wealth of genes in the population of active, autochtonous (endangered) breeds. The results of the investigations are used as the base for forming gene collections of the endagered breeds- Buša, Istrian cattle, Ruda and Prameneka sheep, Turopoljska and Pfeifer pig and others. So far protein polymorphisms of blood and milk in the Istrian, Slavonian-Podolic and Simmental cattle have been studied. Nucles of gene collections "in situ" have been established for the Istrian and Slavonian-Podolian cattle and Turopolje pig.

Research goals: To determine the current state of genetic protein polymorphisms of blood (transferrin, posttransferrin,haemoglobin, postalbumin and others), including the enzimes (amylase, carboanhydrase), and milk (ŕ-, á- and k-casein, á-lactoglobulin and ŕ-lactalbumin) in the breeds as well as significant pheno- (geno-) types of cattle in Croatia. This will help in defining the current genetic structure i.e. the purity of the breed. Establishing the present gene frequencies will contribute to understanding the level of relationship between the breeds, the justifications of defining certain breeds and the endangerment of some genes due to sampling. Practical production benefit will be achieved in a short time by getting to know the correlation of some types and frequencies of protein with the production characteristics of the cattle. This will improve the choice of sires and dams in the national breeding program. Some cattle breed are in danger of extinction. They are the autochtonous low productive breeds. Their protection has a genetic (keeping natural variability), philological, etnografic, ethic, productive and other significance. The project will include systematic work on "ex situ" and "in situ" protection. This will be carried out by establishing herd nucleus in the autochtonous environment an by freesing semen and embryos. The priority in forming gene collections is geven to the Istrian and Slavonian-Syrmian Podolian cattle, the Turopolje and black Slavonian (Pfeifer) pig, the Hrvatica hen and other breeds.
