In the European context of increased restrictions in the use of exogenous hormones in breeding systems, this project aims at providing the dairy goat industry with an innovative and sustainable technology to ensure the hormone-free production of milk of goats and related products. Experiments, based on the use of the male effect and light treatments are carried out in order to obtain a high-level of oestrus synchronization and thus to optimize AI conditions, in and out of the breeding season. Photoperiodic treatments without melatonin and progestagen-free (prostaglandin-based) / hormone-free AI protocols are being tested. The first results show that the male effect is a very promising non-pharmacological alternative to the use of hormones for inducing and synchronizing oestrus in some breeds of goats. Depending on the breed and.or the time of the year, a photoperiodic treatment of the females and/or the males might be necessary to optimize the response to the male effect.
