Response of spermatozoa of different breeds of rabbits to hypo-osmotic swelling test
|
|
| Abstract |
A total number of forty sexually mature Rex; Flander; Californian and New-Zealand White rabbit bucks of nine months age were used in this experiment to investigate the response of spermatozoa of these different breeds of rabbit bucks to hypo-osmotic shock test.
The results obtained from this study indicated that, sperm motility in solutions with different osmolarities (300 or 100 mOsmol/ L) were significantly (P ≤ 0.01) higher, while the percentages of spermatozoa with coiled tails or swollen heads were significantly (P ≤ 0.01) lower at level of 300 mOsmol/ L (normal osmolarity) than 100 mOsmol/ L (osmotic stress), during incubation at 37 oC for up to 60 minutes in all studied rabbit breeds.
Advancement of incubation time up to 60 minutes of rabbit semen in solutions with different osmolarities decreased significantly (P ≤ 0.01) semen quality of all studied rabbit breeds. The progressive sperm grades and percentages in both osmolarities used (300 and 100 mOsmol/ L) were significantly (P ≤ 0.01) arranged descendingly, while the percentages of spermatozoa with coiled tails or swollen heads were significantly (P ≤ 0.01) arranged ascending as recorded by Rex followed by Flander, Californian then New-Zealand White rabbit bucks, respectively.
Key words: Rabbit, breeds, season, semen, HOS-test.
