Abstract(s)

Goat production in Portugal, even for milk, is based on indigenous breeds in extensive systems. Reproduction is based in April/May mating, with the kidding period in September/October. Artificial Insemination (AI) is a fundamental tool to implement breeding schemes for those breeds, which never had any improvement scheme, other than done empirically by the owner/shepherd. Te goal is to identify the necessary interval between kidding and oestrous synchronization or AI, in order to obtain acceptable reproductive parameters.
