Table 3 Effect of protein fractions of llama seminal plasma on corpus luteum (CL) development in llamas (mean ± SEM)

From: Biochemical isolation and purification of ovulation-inducing factor (OIF) in seminal plasma of llamas

  Seminal Plasma
(n = 10)
Fraction B
(n = 2)
Fraction C2
(n = 10)
Day CL detected (Day 0 = treatment) 2.9 ± 0.1a 2.5 ± 05ab 2.1 ± 0.2b
Maximum CL diameter (mm) 11.0 ± 0.4a 12.0 ± 1.0ab 13.3 ± 0.4b
CL diameter at Day 8 (mm) 10.4 ± 0.4a 11.3 ± 0.3ab 12.4 ± 0.4b
CL diameter on Day 15 (mm) 4.9 ± 0.2a 4.5 ± 0.5a 6.4 ± 0.5b
  1. Female llamas were given whole seminal plasma (SP, positive control), Fraction B (isolated by hydroxylapatite column chromatography) or Fraction C2 (isolated by gel filtration chromatography).
  2. a,b Values with no common superscripts are different (P < 0.01).
