| Abstract | ||
| The Study was conductedat the Department of Reproductive Physiology/Veterinary College/ University of Wrocrow/Poland. to find out effect of month, and breed on some physical traits of semen (sperm concentration, motility, types of spermatozoa speeds, speed tracks ,abnormality during the period from 3/9 – 28/5/2010. Results revealed that, that breed and months had significant differences in sperm concentration, sperm motility especially forward swimming movements during months of studying.Australian Merino rams showed highly significant effect on sperm speeds .The interaction between breeds and months showed significant (P<0.05) effect on the such trail. Whereas, polish rams spermatozoa showed highly fixed speeds.Polish rams showed significantly highly (P<0.05) sperm speed tracks during all months of the year specially the track of 35.1-1000 in comparison with the Australian Merino rams..Australian Merino rams showed significant differences in the level of all studies (VAP, VSL, STR and ALH). As well as, there were significant differences in their levels due to month, breed and month - breed interaction effects | ||
