hormonal treatments may also help to stimulate anovulatory cows to cycle,particularly if combined with increased energy supplementation or reduced suckling stimulus.For example, treatment of postpartum beef cows with aprogestin implant was found to increase LH pulses if combined with removal of the suckling stimulus.As shown in Table 3, there is an increase in number of LH pulses with removal of the suckling stimulus.In addition, insertion of a progesterone implant further increased LH pulses. Thus,low levels of progesterone may actually increase LH pulses with resulting increases in follicle development.
