The aim of the research was to evaluate the genetic structure of Ukrainian Holstein cattle (n = 150) of the state enterprise Chayka (Kiev region, Ukraine) on the basis of the analysis of 12 microsatellite DNA loci and 3 QTL genes: k-casein (CSN3), prolactin (PRL), and fatty acid synthase (FASN). A total of 93 allelic variants were identified, and the largest number of alleles were found for TGLA53, TGLA122 and TGLA227 loci, the mean PIC = 0.693, and the heterozygosity index for all loci was 0.7314. The greatest number of effective alleles per locus were found for the BM1824 locus. Based on association analyses, complex genotypes were established for the three genes (CSN3, PRL, FASN). It was found that the AAPRL AACSN3 AAFASN genotype determined the highest milk yield (8351 kg / lactation) and the protein content in milk (3.10%), whereas the AAPRL ABCSN3 GGFASN genotype determined the highest level of fat content in milk (3.80%).
期刊介绍：
"Medycyna Weterynaryjna" publishes various types of articles which are grouped in the following editorial categories: reviews, original studies, scientific and professional problems, the history of veterinary medicine, posthumous memoirs, as well as chronicles that briefly relate scientific advances and developments in the veterinary profession and medicine. The most important are the first two categories, which are published with short summaries in English. Moreover, from 2001 the editors of "Medycyna Weterynaryjna", bearing in mind market demands, has also started publishing entire works in English. Since 2008 the periodical has appeared in an electronic version. The following are available in this version: summaries of studies published from 1999 to 2005, full versions of all the studies published in the years 2006-2011 (in pdf files), and full versions of the English studies published in the current year (pdf). Only summaries of the remaining studies from the current year are available. In accordance with the principles accepted by the editors, the full versions of these texts will not be made available until next year.
All articles are evaluated twice by leading Polish scientists and professionals before they are considered for publication. For years now "Medycyna Weterynaryjna" has maintained a high standard thanks to this system. The review articles are actually succinct monographs dealing with specific scientific and professional problems that are based on the most recent findings. Original works have a particular value, since they present research carried out in Polish and international scientific centers.
