Hodnocení kvalitativních parametrů ejakulátu psů

The dog has been accompanying men for eons, according to some literary sources the dog is the very first domesticated animal. My study included 152 dogs of 43 breeds. n total we had 408 ejaculates. We evaluated the proces of collection. Each ejaculate was evaluated on content, sperm count and motility of semen and morphological examination of semen.The evaluation of content and quality of ejaculate brought following average results. Time of ejaculation was 413,16 +- 168,66 seconds; the volume of ejaculate was 8,49 +- 6,51 ml; motility of semen 71,2 +- 16,8 %. There was approximately 69,1 +- 15,7 % of morphologically normal semen in the evaluated ejaculates. The results show, that you can expect quality ejaculate from middle sized sporting dogs. The dogs should be fed with a complete food mixture. The dog should be used for stud from the age of 2 years and in ideal conditions should not mate more often than once a week
