Abstract
The Hungarian Large White and Hungarian Landrace pig breeds have outstanding lifetime performance, production parameters and crossbreeding ability. Nevertheless, during the recent decades, these breeds could not compete with the West European hybrid pigs concerning on production results. In this study, we made a complex andrological evaluation of boars in different Hungarian nucleus breeding stocks. After taking blood and semen samples, performing gonadotropin-releasing hormone (GnRH) challenge, ultrasonic and thermographic examinations were done. Laboratory tests were accomplished in reproduction labs of NARIC ABNMS. Our goal was to determine the reproductive performances of boars and collect samples for future genetic examinations, respectively.

Summary
Swine plays an important role from the aspect of food supply and the economy. During the recent decade, around 40% of the world’s meat consumption was pork (Xiaodong et al 2012). There are several swine races resistant to different environmental factors e.g. cold and hot temperature, various pathogens and diseases. These animals can adapt to the extreme conditions of their area (Chen et al 2007). It is very important to achieve the best results of production. One of the most prominent features is reproductive performance. Economic activity can be significantly influenced by the reproductive success. The Hungarian Large White and Hungarian Landrace reportedly have very good life span performance, production parameters and crossbreeding ability. During the recent decades, these breeds could not compete with the West European crossbreeding pigs concerning production results
