Maria Font explained the activities carried out during the project with the aim of reducing the sexual odour of whole males and improving their detection, different protocols for applying immunocastration have been studied as an alternative to surgical castration, genetic markers linked to sexual odour have been evaluated and two methodologies have been worked on to determine sexual odour: the human nose (known as ‘human nose’) and Raman spectroscopy.
Jacobo Álvarez presented the first results of using the Raman sensor for automatic sexual odour detection. The prediction of androstenone and escatol is made with an indirect determination, from the measurement of the profile of composition of fatty acids in the subcutaneous tissue. He confirmed the feasibility of using this technique as a triage method, although the precision achieved so far is insufficient. More samples will soon be measured to improve the accuracy and robustness of predictive models.
