4.3. Buck effect
Does and bucks are sensitive to their social environ¬ment, which can be used to manage their reproductive cycle. The so-called male effect is a technique to stim¬ulate the sexual activity in seasonally anovulatory goats (Pellicer-Rubio et aL, 2007). Most female goats have a short ovarian cycle of 5-7 day-length following the introduction of bucks, followed by a second ovulation associated with oestrous behaviour and a normal luteal phase (Chemineau et al., 2006).
