13 Ejaculate Characteristics Semen Standards Motility 50-70% Morphology 90% Volume ml Concentration 2 to 4 billion per ml White blood cells <5%
14 Semen Collection & Evaluation Collection Methods Semen characteristics in bucks collected by artificial vagina (AV) or electro ejaculator (EE)
15 Semen Collection & Evaluation Techniques for determining sperm cell concentration in the semen Visual appraisal Thick, chalky appearance indicates high concentration Spectrophotometer Calibrated using a standard curve and comparing sample Hemocytometer Glass slide with precision grid etched within
16 Semen Collection & Evaluation Techniques for determining sperm cell concentration in the semen Hemocytometer 1.Sub-Sample Dilution (1:200) 2.Place sample on hemocytometer 3.Count sperm cells in 5 squares 4.Multiply Step 3 by 5 = cells/0.1 mm 3 5.Use the following equation to determine concentration (cells/ml) Sperm cells/ml = cells/0.1mm 3 X 10 X Dil Rate (200) X 1000
17 Semen Collection & Evaluation Techniques for determining sperm cell concentration in the semen Hemocytometer Example 112 cells/5 squares 560 cells/0.1mm 3 ( i.e. 112 X 5) 1.12 billion cells/ml= 560 cells/0.1mm 3 X 10 X Dil Rate (200) X 1000
18 Semen Collection & Evaluation Determining the number of units from a collection: 2 ml ejaculate collected from a ram 70% Progressive Motility 1.12 X 10 9 Cells/mL 1. Adjust for motility 1.12 X 10 9 Cells/mL X 0.70 = X 10 9 Motile Cells/mL 2. Determine total number of motile cells in ejaculate X 10 9 Motile Cells/mL X 2 = 1.57 X 10 9 Motile Cells 3. Determine number of units (if we need 40 X 10 6 Motile Cells/Unit) 1.57 X 10 9 Motile Cells / 40 X 10 6 = 39.2 Units
