KOUBA, Jindřich
The aim of this thesis was the study of available publications covering the topic of breeding bulls nutrition, the analysis of the feed dose and the evaluation of the semen quantity and quality after addition of extruded flaxseed (EL) to the feed dose. 200 semen samples from 8 breeding bulls of the Czech Fleckvieh were proposed as the subject of observation. The influence of EL to the sperm motility and concentration and to the amount of semen was observed and evaluated. The positive effect was found out in all of the observed characteristics. Experimental group showed increase in the amount of semen in comparison to the control group, and the statistical analysis displayed a significant difference in the effect of the time factor (effect of the addition of EL) on the amount of semen within the groups. The sperm concentration in 1 mm3 of semen of the experimental group increased compared to the control group, but the difference was not statistically significant. The experimental group showed an increase in sperm activity and the time factor was statistically significant. From the results of this thesis follows that extruded flaxseed can be recommended as the suitable feed supplement for breeding bulls.
