J. WEIS, C. HRNČÁR

Abstract


On basic certificates about acceptation of Oravka Plymouth Rock, Rhode Island, New Hampshire, White Leghorn, Brown Leghorn and Sussex, controlled flocks of Slovak Union of Breeders, we analyzed total number of birds, number of breeding males, number of breeding females and effective population size by Simon and Buchenauer (1993 ) and we evaluated the populations of observed hen’s breeds to categorisations by Scherf (2000). The highest number of birds we recorded at breed New Hampshire from observed hen’s breeds. Average total number of animals in period of year 2003 - 2008 was 1373 birds with average effective population size 445.103. However, the population of New Hampshire poultry in Slovakia was evaluating by massive decrease in last years as a endangered - maintained breed for which an active conservation programme is in place. By contrast, the smallest number of animals was detected at breed White Leghorn with average total number 18.83 birds in period of year 2003 - 2008 and average effective population size 6.605. The breed White Leghorn in Slovakia we categorized to critical breed. National legislation on Slovakia has been created, the fist experience is being gathered and the European legislation is coming in practice. The conditions for the development and preservation of endangered breeds of poultry in Slovak Republic in the long term are being put in place by means of creative and well aimed utilisation of European and national legislation.
