The goat is a seasonal breeder and usually gives birth once a year. The earliest sign of pregnancy after mating or artificial insemination (AI) is the absence of oestrus. This can only be detected during the oestrous season, but even then not all non-pregnant goats will return to oestrus. Another complicating factor is that some pregnant goats may show signs of false heat. For a more evenly distributed milk production through the year, farmers sometimes want their does to give birth in the autumn. This means that oestrus and ovulation have to be induced by hormonal treatment during the anoestrous season. Unfortunately, the pregnancy rate after mating during the anoestrous season is always lower than that during the oestrous season (Corteel et al. 1982). It is assumed that mating after hormonal treatment will result in more pseudopregnancies (Mizinga et al. 1984).
