Extract

While cystic follicles remain a significant problem in dairy cows, their aetiology still remains unclear. Recent studies have shown that treatment with low levels of progesterone can interfere with the induction of an LH surge and induce cystic follicles leading to the theory that supra basal concentrations of progesterone may act as a trigger for the formation of cystic follicles (Silvia et al., 2002).
