| Abstract |
Forty five male dromedary camels (Camelus dromedariur) of 500 to 600 kg body Weight, were used in the present study. The camels were divided into three groups according to their ages as follows: from 5 to 10, over 10 to 15 and over 15 to 20 years old in the first second and third groups, respectively. Testicular measurements, copulation time, semen characteristics and some blood components were recorded.
The results showed that testes weight (gm) in the camels at 10 to 15 and 15 to 20 years was significantly (P<0.0l) higher, while insignificantly lower in testes tone firmer score than camels at 5 to 10 years old. Testicular volume (cm3) and scrotal circumference (cm) in the camels at 10 to 15 years increased significantly (P<0.01) as compared to camels at 5 to 10 and 15 to 20 years old. Copulation time (minutes) was significantly (P<0.05) longer in the camels at 5 to 10 and 10 to 15 years than camels at 15 to 20 years old. Semen color was creamy white in the camels at 5 to 10 and 10 to 15 years and milky white in the camels at 15 to 20 years old. Semen consistency was viscous in the camels at 5 to 10 and 10 to 15 years and semi-viscous in the camels at 15 to 20 years old. Seminal hydrogen-ion concentration (PH) value showed insignificantly higher, while sodium concentration (mg/ 100 ml) was significantly (P<0.01) higher in the camels at 15 to 20 years than camels at 5 to 10 and 1 0 to 15 years of age. Semen-ejaculate volume (ml), total protein concentration (gm/100 ml), calcium and potassium concentrations (mg/100 ml) showed significantly (P<0.05 or 0.01) increased in the camels at 5 to 1 0 years as compared to camels at 15 to 20 years, while insignificantly increased in the camels at 5 to 10 years as compared to camels at 10 to 15 years of age. Percentage of sperm motility, sperm-cell concentration (x106 /ml) and total-sperm output (x106/ ejaculate) were significantly (P<0.01) higher, while the percentages of dead spermatozoa, Sperm abnormalities and acrosomal damage of spermatozoa (%) were significantly (P<0.01) lower in the camels at 5 to 10 and 10 to 15 years than camels at 15 to 20 years old. Albumin and globulin concentrations (gm/100 ml) were insignificantly decreased in the camels at 15 to 20 years as compared to camels at 5 to 10 and 10 to15 years old. Total cholesterol concentration (mg/100 ml) was significantly (P0.01) higher in the camels at 10 to 15 years than camels at 5 to 10 and 15 to 20 years old. Activities of aspartateaminotransferase (AST), alanineaminotransferase (ALI) and alkaline phosphates (ALP) enzymes (U/L) were significantly (P<0.01) higher in the camels at 15 to 20 years than camels at 5 to 10 and 10 to 15 years old. Inorganic phosphorus (mg/100 ml), zinc (µg/100 ml) and testosterone concentrations (ng/100 ml) were significantly (P<0.01) higher in the camels at 5 to 10 years than camels at 10 to 15 and 15 to 20 years old.
