Wild felids reproductive biotechnology in the male: a review

Abstract

Wild cat species are often in a vulnerable or endangered situation around the globe. One of the questions on which the researchers’ efforts have focused is on aspects of reproduction with specimens in captivity, or on collecting genetic materials from wild animals for their multiplication in captivity. The objective of this review was compilation, ordering and synthesis of scientific information about biotechnologies in wild cats. This review was carried out compiling information published online on the subject for a period of 18 months; the information was synthesized and grouped into subtopics. Among the topics to highlight focus in the male parent approach allows for greater dispersal of genetic material compared to the female parent. During the application of technologies that assist reproduction, the collection, analysis and cryopreservation of semen is carried out, as well as the measurement of physical characteristics of the animals correlated with reproductive aspects. The main findings indicate that the investigation of methodologies such as seminal harvest by urethral catheterization, the development of cryopreservation protocols, and computer-assisted analysis of spermatic behavior are emerging biotechnologies, which allow expanding knowledge about the reproduction of felids. However, it should be considered for future research that the processes must be adapted for in situ work. In conclusion, the generation of information on these reproductive biotechnologies is a fundamental aspect for supporting sparse populations, to avoid the removal of specimens from their natural habitat, or the reintegration into it
