DEPENDENCIES BETWEEN PRL GENE POLYMORPHISM AND PRODUCTION PROGRESS IN POLISH HOLSTEIN-FRIESIAN BLACK-AND-WHITE COWS
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2017, Vol 44, Issue 338
Abstract
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.
