For the Biotechnology Session 16 abstracts were submitted, from which 4 were selected for oral presentations for the Thematic Session in Biotechnology. The first authors of the papers came from Slovakia (2 oral presentations + 8 posters), Romania (1 + 4) and Czech Republic (1 + 0).
The scientific topics presented in the Thematic Session were quite heterogeneous, ranging from boar and bovine spermatogenesis to antimicrobial activita of Strptomyces species and feeding techniques of cattle.
Iulian Ibanescu introduced into the topic of seasonal variation of sperm quality parameters in boar. In contrast to previous publications of other authors the outcome of the presented paper suggested that the standardization of exploitation conditions of boars by maintaining controlled climate conditions in the farm can reduce the effect of heat stress on spermatogenesis during summer. This potentially offers opportunities against and variations of sperm quality parameters and thus seasonal infertility during the year.
The presentation of Eva Tvrdá on antioxidant efficiency of resveratrol on oxidative stress- induced damage in bovine spermatogenesis nicely complemented the previous paper on boar spermatogenesis. As a take-home message of her presentation Eva Tvrdá suggested that resveratrol may be a suitable supplement for the in vitro management and preservation of male gametes. A lively discussion developed on the practical impact of both presented papers on spermatogenesis, resulting in ideas on establishing collaborations between both groups involved in the studies.
Silvia Kovácsová presented a study on the identification and characterization of Streptomyces species having antimicrobial activity against selected pathogens which where selected according to their importance in agriculture.
M. Psenka presented an ongoing project on a feeding technique called total mixed ration (TMR), which was on the thematic periphery of the biotechnology session. Main goal of the study was the investigation of the accuracy of dosing the individual components into the ration. It was shown and discussed that the precision of dosing was highly variable in different forage feeding systems.
