Effect of protein fractions of llama seminal plasma on circulating LH concentration in llamas. Female llamas were given whole seminal plasma (SP, positive control), Fractions A or B (isolated by hydroxylapatite column chromatography), Fraction C2 (isolated by gel filtration chromatography), or phosphate buffered saline (PBS, negative control). *Interval during which values in SP and C2 were higher (P < 0.05) than in other groups.
