Polymorphism of insulin like growth factor IGF-1gene in selected Polish sheep breeds. Research was carried out in 2009-2013 on 1751 sheep bred in Poland (1366 ♀; 385♂) - 4 meat-wool breeds: Polish Merino, Old type Polish Merino, Corriedale and Żelaźnieńska sheep and 3 meat breeds (Berrichone du cher, Suffolk, Charolaise) from 34 flocks selected randomly across the country. All animals were subjected to identification factor insulin-IGF-1 gene, in the assessment of C and T alleles. Summing up, it should be noted that in 4 meat-wool breeds and 2 meat breeds (Berrichone du cher , Suffolk) there were no polymorphism of alleles and genotypes of insulin-like growth factor (IGF-1) gene, limiting its scope to determine C allele and CC genotype. Only one Charolaise ewe (breed imported from France) had T allele and C:T genotype. That result indicates the need for further research about sheep imported and adapted in Polish production conditions and assess the adaptation process.

The investigations were aimed at the determination of genetic distance among eight lines of laying hens kept in Poland and belonging to the following breeds: GreenLeg ZKF and Z11, Leghorn H22 and G99, Rhode Island Red RD2, YellowLeg Ż33, Polbar (Pb) and Sussex (Sx). The phenotype frequencies of fastmigrating prealbumin (PaF), eggyolk transferrin and ovalbumin (OvA), ovoglobulins: G3, G4 and G2 and conalbumin were obtained from the electrophoregrams of horizontal polyacrylamide gel electrophoresis.
