Abstract
Population genetic indicators of the Hungarian Hucul population were calculated taking also into account the effect of imported horses.The birth year of the examined 3002 individuals ranged between 1871–2015. The last year involved in the examination was 2015, when the research was conducted on the stock under stud book control. The calculations on the population were made using the statistic indicators in the Endog programme, with and without the imported Polish horses. Figures were depicted using R software. Number of offspring of the Polish individuals was presented in tables; the distribution of the offspring per stud and per mare family, as well as the Nei’s genetic distance,were presented graphically.
Highlights
Based on pedigree data the impact of seven individuals was examined on the structure of the Hungarian Hucul horse population
The aim of our examinations was to evaluate the genetic structure of the Hungarian Hucul population based on pedigree data, by applying population genetic methods, especially considering the effect of imported horses modifying genetic structure
We examined how the use of the Polish stallions 3139 Polan (Pol), 4122 Goral Parter (Pol), 3883 Goral Ploskor (Pol), 5137 Hroby Bryf (Pol), 4677 Hroby Grad (Pol), 3921 Pietrosu Jadeit (Pol) and the mare Hroby Wilia (Pol) in the breeding influenced certain population genetic indicators of the whole population and of the reference stock
Summary
Based on pedigree data the impact of seven individuals (purchased in Poland) was examined on the structure of the Hungarian Hucul horse population. Immigration has on important role in endangered species such research is justified and may help in developing breeding programmes and mating schemes. It helps in setting the direction and determining the extent of the adjustment; may serve as guidance as regards the nature of the immigration and the practical mating systems and thereby help in sustaining the diversity of the populations. The aim of our examinations was to evaluate the genetic structure of the Hungarian Hucul population based on pedigree data, by applying population genetic methods, especially considering the effect of imported horses modifying genetic structure. The impact of imports was examined by Lámfalusy (2012) who studied the effect of 14 imported stallions on inbreeding in the case of Lipizzaner horses. Bartolomé et al (2011) conducted research on Spanish sports horses and Koenena et al (2004) studied sports horses from various countries examining the same effect
