Seasonal changes in characteristics of the semen were associated with seasonal changes in temperature, indicating the detrimental effects of heat, even on indigenous stock.","PeriodicalId":75426,"journal":{"name":"Acta veterinaria Scandinavica.

This requires, among other things, major embryo-technological efforts, and the rate of success is still far from an acceptable level in the domestic species. It is currently poor, but the progress is very good. In this brief review certain embryo-technological problems will be addressed with the focus on the pig as potential organ donor. In addition, certain views of the Danish ad hoc Committee on Gene Technology on xenotransplantation will be presented in this context as they are supposed to mirror the concern and the views of the issues important for the public and each individual.</p>","PeriodicalId":75426,"journal":{"name":"Acta veterinaria Scandinavica.
