Description
| - Předmětem této studie bylo porovnat rozdíly v produkci spermatu u kanců mezi obdobími 1990-1997 a 2000-2007 za použití rozsáhlého souboru dat z inseminačních stanic. Byly analyzovány tyto údaje: objem spermatu, koncentrace spermií, progresívní pohyb spermií a podíl abnormálních spermií. V období 2000-2007 se projevil stoupající trend u množství spermatu. Opačný trend (stagnace nebo snížení) se objevil u kvality semene. U kříženců se také snížil heterozní efekt. (cs)
- The objective of this study was to compare the differences in boar sperm output between periods 1990-1997 and 2000-2007 using a large data set from artificial insemination centers. These data were analyzed: semen volume, concentration of spermatozoa, progressive motion of spermatozoa and proportion of abnormal spermatozoa. The period 2000-2007 showed an increasing trend of sperm quantity. In contrast, the stagnation or decreasing trend of sperm quality was recorded. In crossbreds, a lower manifestation of heterosis was observed as well.
