Reproductive activity after induced anestrus using altrenogest in Tursiops truncatus females in captivity in marine environment

i nterest to reproduce Bottlenose dolphin ( Tursiops truncatus ) in captivity has increased due to the international restrictions for its commercialization and the risks and logistical difficulties for transporting specimens. Therefore, it has become important to study its reproductive biology in...
