First live offspring of Amazonian brown brocket deer (Mazama nemorivaga) born by artificial insemination

The Amazonian brown brocket deer ( Mazama nemorivaga ) is an endemic species of the Amazon rainforest region, which has suffered constant threats due to hunting and increasing deforestation. Artificial insemination (AI), combined with genomic banks, is considered an important tool for maintaining conservation programs of endangered species; however, the number of live offspring born from AI in non-domesticated cervids is extremely low. Thus, studies designed to develop, adapt, or enhance AI techniques are of fundamental importance. This report describes a successful transposition of the cervix with semen deposition in the uterine lumen of a M. nemorivaga female, based on the transcervical AI technique used in sheep, as well as using specific tools develop for IA in small ruminants, which have resulted in the birth of a healthy male fawn.
