| Abstract |
Total number of 12 NZW rabbit bucks with average live body weight of3.25±0.41kg and 7 months of age were divided into 2 groups, 6 animals in each group. Bucks in the 1st group were served as a control (untreated), while those in the 2nd group was weekly intramuscularly injected with one ml from Tonyphosphan (140 mg phosphorous). Semen was collected from all bucks in each group with an artificial vagina once weekly for 13 wk (4 wk as primarily period and 9 wk as a main semen collection period). The ejaculate volume (ml) was measured, semen mass motility, progressive sperm motility, livability, abnormality, sperm cell concentration were evaluated and concentration of fructose and phosphorus was determined in raw semen. Also, concentrations of total proteins, albumin, phosphorous and testosterone were determined in blood plasma. At the end of the collection period, three bucks from each group were slaughtered and morphometric characteristics of testes and epididymal regions (length, width and thickness) were estimated Also, histometric characteristics were determined Results show that ejaculate semen volume slightly increased in treated than the control group (0.704 vs. 0.771 ml). Percentage of mass motility (44.3 vs. 57.3%), progressive motility (53.75 vs. 69.6%), live sperm (76.2 vs. 90.0%) and sperm cell concentration (310.6 vs. 493.3 x106/ml) increased (P<0.00l) in phosphorus as compared to the control group. Total sperm abnormalities were lower (P<0.05) in phosphorus than that in control group (7.2 vs. 12.9%). Sperm outputs in term of total, motile, live and normal spermatozoa were higher (P<0.00l) in phosphorus than that in control group. Fructose and phosphorus concentration in raw semen increased (P<0.00l) in treated than that in control group (472.1 vs. 223.3 mg/dl and 30.5 vs. 28.6 mg/dl, respectively). Phosphorus treatment resulted in increase (P<0.00l) in concentration of total protein (4.53 vs. 6.41 g/dl), albumin (2.18 vs. 3.56 g/dl), globulin (2.38 vs. 2.84 g/dl), phosphorous (6.98 vs. 9.10 mg/dl) and testosterone (1.666 vs. 2.214 ng/ml) compared with control group. Only averages of absolute weight and relative weight of epididymal caput as well as average length of epididymal cauda were higher (P<0.05) in treated than in control group. However, all testicular measures, averages length and thickness of epididymal caput, and averages absolute and relative weight, and thickness of epididymal cauda were not significantly affected by phosphorus injection Proportional area occupied by epididymal tubules was significantly (P<0.05) higher by about 71% and proportional area of stroma was significantly lower by about 104% in treated than in control group. However, all histometric measures of the testis and epididymal caput well as mean diameter, lumen and density of epididymal tubules in caput were not affected significantly by phosphorus injection. The current study indicated beneficial effects of weekly injection with one ml from Tonyphosphan (140 mg phosphorous) on "men quality of rabbits in term of improving most semen physical characteristics, total sperm of motile, normal and live outputs.
