    Dependencies between PIT-1 gene polymorphism and production progress in polish holstein-friesian black-and-white cows
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Pytlewski, Jarosław; Antkowiak, Ireneusz R.; Stanisławski, Daniel; Czerniawska-Piątkowska, Ewa; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Computer Lab, Poznań University of Life Sciences; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin
    The aim of this study was to analyse the dependence between PIT-1 gene polymorphism in exon 6 of bovine chromosome 1 (c.1178G>A) and the level of production progress in Polish Holstein-Friesian Black-and-White cows. The greatest annual production progress and cumulative progress for the yield of milk and milk fat was found for the AA homozygotes. For the yield of milk protein more advantageous values of calculated parameters were recorded for the GG homozygotes.

    Dependencies between prl gene polymorphism and production progress in polish holstein-friesian black-and-white cows
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Pytlewski, Jarosław; Antkowiak, Ireneusz R.; Stanisławski, Daniel; Czerniawska-Piątkowska, Ewa; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Computer Lab, Poznań University of Life Sciences; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin
    The aim of this study was to analyse dependencies between PRL gene polymorphism within exon 4 of bovine chromosome 23 (locus g.8398G>A), and the level of production progress in milk yield, yields of milk fat and milk protein in Polish Holstein-Friesian Black-and- -White cows. Results of this study indicate dependencies between genotype at locus g.8398G>A of the PRL gene and production progress in terms of milk yield as well as the yields of milk fat and milk protein. The greatest production progress and cumulative progress for milk yield as well as yields of milk fat and milk protein were shown for the AG heterozygotes at locus g.8398G>A, while the lowest values of analysed parameters were recorded for the AA homozygotes.
