Cím:	The impact of Polish breeding animals on the genetic structure of the genetic structure of the Hungarian Hucul horse population / Somogyvári Enikő, Posta János, Mihók Sándor
Dátum:	2018
Megjegyzések:	The impact of Polish imported horses on certain population genetic indicators of the Hungarian population of the Hucul breed was analysed. The dataset covered birth years between 1895 and 2015. The registered breeding stock in 2015 was chosen as reference. Calculations with the Endog programme were performed on the whole population as well as on the reference stock with and without the imported Polish horses. As an effect of the immigration, the average inbreeding coefficient of the whole population fell from 5.83 % to 5.6 %. The same value of the reference stock fell from 9.06 % to 6.8 %. The average degree of relation in the whole population was 10.45 %, which changed to 10.55 % as an effect of the imported animals. Average degree of relation in the reference stock was 13.69 %, which was reduced to 12.7% thanks to the involvement of the Polish breed. The mean value of the generation interval, 10.98 years changed to 12.53 without the imported animals. The equivalent complete generation increased to 6.06 from 5.62 with the inclusion of Polish animals for the total population whereas it remained 8.72 for the reference stock. Maximum number of generations changed from 13.32 to 14.24 (total population) and from 19.04 to 19.46 (reference stock). The number of complete generations increased from 3.5 to 3.77 for the total population and decreased from 5.55 to 5.45 for the reference stock. Effective number of founders (total population: from 21 to 22, reference stock from 19 to 23), effective number of ancestors (total population: from 18 to 20, reference stock from 14 to 15), ratio of effective number of ancestors and effective number of founders (total population: from 0.857 to 0.9090) increased whereas it was decreased (from 0.7384 to 0.6521) for the reference stock with importing Polish animals.
