Table 1 Quantitative and qualitative semen characteristics of stallion ejaculates (number of ejaculates per stallion within brackets) used in this study (mean ± SD).

From: Sperm morphology and chromatin integrity in Swedish warmblood stallions and their relationship to pregnancy rates

Stallion (no. ejaculates) Concentration (×106/mL) Motility (%) Spermatozoa with normal morphology (%)
A (4) 201 ± 67 69 ± 13 69.9 ± 8.3
F (4) 356 ± 58 57 ± 14 75.6 ± 2.8
G (3) 216 ± 44 55 ± 8.7 77.5 ± 4.0
H (3) 228 ± 50 73 ± 5 31.2 ± 4.0
K (4) 162 ± 88 68 ± 5 71.8 ± 2.1
Q (4) 254 ± 88 71 ± 6 66.5 ± 7.8
R (4) 254 ± 86 65 ± 5 72.5 ± 2.8
T (4) 165 ± 47 68 ± 6 73.1 ± 2.1
W (3) 175 ± 38 63 ± 6 50.3 ± 2.9

  1. Notes. Concentration was determined by Spermacue. Differences between stallions were significant for concentration (P = 0.03) and normal morphology (P < 0.001) but not for motility (P0 0.1). Differences between ejaculates for each stallion were not significant for concentration, motility or normal morphology.
