Manipulation of ovarian activity in camelids

Abstract

Camelid production has increased in importance in the world in recent years. The high demand for genetically superior males and the implementation of reproductive technologies requires the synchronization of ovarian follicular waves. This paper describes the state of knowledge regarding seasonality and follicular wave patterns in camelids. Reproductive seasonality in camels can be manipulated using artificial photoperiod or melatonin treatment. As in other ruminants, protocols for follicular wave synchronization are based on the elimination of the dominant follicle (induction of ovulation) or progesterone treatment. These protocols are described for breeding management and ovarian superstimulation in embryo donors. Induction of ovulation and initiation of superstimulation 2-4 days later (emergence of a new follicular wave) results in higher response in terms of number of ovulations and collected embryos.
