DEPENDENCIES BETWEEN PIT-1 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 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.
