    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Głosińska, Joanna; Kowalewska-Łuczak, Inga; Kulig, Hanna; Wojdak-Maksymiec, Katarzyna; Department of Genetics and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland; Department of Genetics and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland; Department of Genetics and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland; Department of Genetics and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland
    The aim of the following study was to determine the influence of genotypes in the polymorphic region of UCP3 gene on the selected traits of milk performance (milk yield, protein, fat and the content of protein and fat). A herd of 169 Polish Red-and-White Holstein-Friesian cows was studied. The analysis of genotypes of individuals was performed using the PCR- -RFLP method. By analyzing the frequency of alleles and genotypes of UCP3/MaeII, in the tested herd of Polish Red-and-White Holstein-Friesian cows, one can state that the CC genotype occurred with the greatest frequency (0.66). The frequency of the C allele was 0.79. The analysis of obtained results showed statistically significant correlations between the UCP3/MaeII genotypes and individual traits of milk performance.

    SLC27A1 gene polymorphism analysis in relation to milk production traits in Jersey cows
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kulig, Hanna; Kałłas, Tomasz; Kowalewska-Łuczak, Inga; Kunicka, Melania; Wojdak-Maksymiec, Katarzyna; Department of Genetics and Animal Breeding West Pomeranian University of Technology, Szczecin; Department of Genetics and Animal Breeding West Pomeranian University of Technology, Szczecin; Department of Genetics and Animal Breeding West Pomeranian University of Technology, Szczecin; Department of Genetics and Animal Breeding West Pomeranian University of Technology, Szczecin; Department of Genetics and Animal Breeding West Pomeranian University of Technology, Szczecin
    The aim was to establish possible associations between the g.14791C>T and g.14589A>G SNPs in the SLC27A1 gene and milk production traits as well as somatic cell count in milk of Jersey cows. No significant associations were found between the genotypes and the analyzed traits. Further study on a larger number of animals is necessary to determine the potential effect of this SNP on the fat yield and fat content in milk.
