Table 2.
Sperm morphometric measures (n = 30 sperm per rooster; length of entire sperm, head + midpiece, and tail), sperm velocity values, progressive motility % and spermatozoa with VAP > 30 μm/s % in Sharkasi and Dandarawi ejaculates (n = 5 samples per rooster).
| Sharkasi | Dandarawi | Pool StdErr | p-value | |
|---|---|---|---|---|
| Total sperm length (μm) | 99.9 | 99.8 | 1.66 | 0.96 |
| Head + midpiece (μm) | 22.4 | 21.3 | 0.67 | 0.22 |
| Tail (μm) | 77.5 | 78.4 | 1.65 | 0.78 |
| VCL (μm/s) | 82.07 | 79.84 | 0.82 | 0.06 |
| VAP (μm/s) | 42.68a | 40.49b | 0.65 | 0.02 |
| VSL (μm/s) | 31.05 | 29.47 | 0.59 | 0.06 |
| STR | 0.71 | 0.70 | 0.006 | 0.42 |
| Progressive motility % | 33.63 | 31.93 | 0.66 | 0.33 |
| % of spermatozoa with VAP > 30 μm/s | 46.29 | 43.06 | 0.67 | 0.55 |
Means ± SEM was used to express all measurements.
VCL curvilinear velocity, VAP average path velocity, VSL straight line velocity; STR = VSL/VAP.
a,bFor main effects, means within a row without common superscripts differ significantly (p < 0.05).
