Abstract

Developmental programming became an area of interest to understand negative environmental impacts on progeny performance. Recently, the concept that we may be able to harness developmental programming to target animals to their niche in the production system has gained recognition. Female fertility is an area where developmental programming has been moderately successful; however, the mechanisms remain unclear. Although some studies have demonstrated differences in gonadal development and attainment of puberty in response to developmental programming, these have not translated to improved fertility. To improve response to developmental programming, it is critical to identify factors that contribute to inconsistencies across studies.
