Reprodução de felinos selvagens no Brasil (revisão de literatura).

Abstract

Felines originated from thousands of years ago, nowadays having decreased their population and some of the existent species on lists of animals who are threatened of extinction. The Reproduction of felines has been studied even more over the years, due to a new series of methods of research, such as, semen collection by electro ejaculation, analyses of fecal metabolites, among others, which are combined with technology that already has been used on routine of laboratories of reproduction in many years, such as vaginal cytology. Many species have the same characteristics to the others, like copulaovule- inducing, however, the Wiedii Leopardus is different from the others, which the female this specie is not the ovule-inducing. Each specie has their own specifications with estrus duration, duration time of estrous cycle, weaning time of gestation, gonadosomatic index, seminal volume, seminiferous tubule length, among other. Demonstrating that even though they inhabit the same territories and biomes, they show distinct characteristics from others. This work aims to discuss playing wild cats in Brazil.
