title: Biophysical and biochemical characteristics of bactrian camel semen collected by artificial vagina.
abstract: Seminal characteristics were investigated in Bactrian camel in this study. Semen samples from ten mature Bactrian camel bulls were collected using a modified bovine artificial vagina. The biophysical parameters including volume, color, sperm concentration and fast forward progressive motility, percentage of live sperm and the biochemical parameters including osmolarity, pH, glucose, calcium, phosphorus, chloride, triglycerides, phospholipids, total protein, albumin and non-protein nitrogen concentrations in seminal plasma were measured. 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 H(2)O. The pH of semen was slightly alkaline (7.4 +/- 0.03). The mean concentration of spermatozoa was 414.8 +/- 25.04 x 10(6)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 +/- 100mg/dl, respectively. The average concentrations of phospholipids and triglycerides in seminal plasma were 36.4 +/- 2.1 and 101.6 +/- 5.5mg/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.
