Studies related to DNA extraction are becoming more ambitious in the sense that large studies are intended to be carried out with minimum DNA sources. The DNA extracted must be of quality for genetic, forensic, population and genomic studies, these samples must be easy to obtain and product of efficient manipulation.Samples obtained from horsehair are an important technical challenge since they constitute the preferred non-invasive sample for genetic studies in horses, which has been shown to obtain reliable results in a short time. In this sense, working into effective techniques to optimizeDNA extraction of scarse samples is a pertinent task. In this study, different DNA extraction methods were evaluated from mane samples obtained from a population of wild horses from the Region of Arauca in eastern Colombia.Three DNA extraction methods were evaluated (phenol chloroform, alkaline lysis and twocommercial DNA extraction kit), DNA concentration, purity and qualityweredeterminate and PCR amplification product were obtain using primers for a hypervariable region of DNA mitochondrial. DNA preparation from hair roots using alkaline lysis was the most economical and efficient method with which it was possible to obtain high quality and quantity DNA.
