Biophysical and biochemical characteristics of bactrian camel semen collected by artificial vagina

The mean time for semen collection was 5.3 ± 0.29 min. The volume of semen varies from 1.2 to 26 (8.2 ± 0.7 mls). The majority of semen samples (83.6%) were milky in color and consistency. The average osmolarity of semen was 316.1 ± 1.48 mOsm/kg H2O. The pH of semen was slightly alkaline (7.4 ± 0.03). The mean concentration of spermatozoa was 414.8 ± 25.04 × 106 cells/ml. The fast forward progressive motility of spermatozoa was 62.4 ± 1.57%. The percentage of live spermatozoa was 85.6 ± 1.15. Seminal plasma concentration of glucose was 35.8 ± 0.9 mg/dl. Non-protein nitrogen, total protein and albumin were 32.5 ± 2.5, 2200 ± 100 and 1100 ± 100 mg/dl, respectively. The average concentrations of phospholipids and triglycerides in seminal plasma were 36.4 ± 2.1 and 101.6 ± 5.5 mg/dl, respectively. The concentrations of calcium, phosphorus and chloride were 8.2 ± 0.1, 2.9 ± 1.7 mg/dl and 97.9 ± 2.9 mEq./l, respectively.
