MIRO-ARIAS, M.; VALLECILLO, A.; LEON, J.M.  y  VEGA-PLA, J.L.. Study of sperm parameters in the Retuertas Horse. Arch. zootec. [online]. 2011, vol.60, n.231, pp.345-348. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000300007.

Geographical concentration and scarce census of the Retuertas horse force to design a complete conservation plan. One of the used tools as a mean of ex situ conservation was the creation of a germplasm bank. Previously, a study of the seminal quality and its aptitude for freezing was developed. Results were: volume 23.25±12.72 ml; concentration 335.83±135.60x10⁶ spermatozoa/ ml; basal motility 3.83±0.98 (1-5) and progressive motility 60.42±15.42 (0-100%); all of them shown significant differences among stallions.
