The research was aimed at determination of genetic variability of Prestice Black-Pied (PC) pig breed (Czech national breed and genetic resource) and to evaluate possible presence of recent bottleneck in this closed small pig population. One hundred and eighty of breeding boars were analysed by eleven tetramer Short Tandem Repeats (STR) panel specifically developed for the genotyping of breeding livestock. Despite the fact that appearance of rare alleles, which may be relatively increased after recent bottleneck, was discovered, the heterozygosity excess was not significant. The PC breed has not undergone recent bottleneck and remained at mutation-drift...

Jan Vrána, Stanislav Mokrý
Acta Univ. Agric. Silvic. Mendelianae Brun. 2020, 68(2), 451-457 | DOI: 10.11118/actaun202068020451
The haptic properties of a product have mostly been underestimated with most studies focusing on visual aspects of objects. Nonetheless, in the last years, it has been found that tactile stimuli are in some cases even more important than the visual ones. However, the traditional paper-based surveys cannot fully and objectively examine their effects on consumers. Therefore, neuroscientific methods, which overcome these obstacles, are becoming more used but there is still only a small number of studies focusing on the effect of haptics in marketing. Using the keywords haptics, tactile input, EEG, fMRI and tactile, seven relevant studies have been found...
