Hodnocení přežitelnosti spermií ovčáckých plemen psů

Topic of this work was evaluation of spermatozoa of shepherd dog breeds, where we took a closer look on evaluation of dog ejaculate quality from FCI I. group. In this work the basic methods of ejaculate evaluation were mentioned as well as special evaluation methods, with focus on durability tests for needs of fresh semen insemination with use of special solutions. For our purposes were chosen 7 dogs, 5 of them were Czechoslo-vakian shepherd of one owner and 2 dogs were German shepherd breed of the second owner. For the best elimination of environmental influences on results these dogs were masturbated in home environment. As solutions we used UHT milk, dry milk, Androhep, Androstar, stallion solution and distilled water. We used standard mathematical-statistic methods for data evaluation
