The new technique allows further progress in the conservation of endangered species

Scientific collaboration by three research teams at the ceiA3 (Agrifood Campus of International Excellence) has enabled a new step in the conservation of endangered felines. The object of their studies is a new technique for the conservation of feline semen, a method that has proven effective in domestic cats, as published in her doctoral thesis by Dr. Emilia M. Jiménez Vaquero.

The research involves collaboration between members of the Departments of Animal Medicine and Surgery, Physiology, Immunology and Cell Biology, and Comparative Anatomy and Pathological Anatomy, of the University of Córdoba. It delves into feline reproductive physiology and the conservation of their sperm, a technique that could help preserve wild felines with conservation strategies applied in-situ and ex-situ. Specifically, the progress achieved is related to the actual effectiveness of certain commercial extenders used in freezing feline sperm and the effect of anesthetics that are commonly used in these processes on sperm quality.

Furthermore, the work of Vaquero Jiménez has studied the effect of cooling in sperm freezability, for the first time describing the sperm vitrification technique in felines,a technique commonly applied in other domestic livestock species of interest.
