The pr.ser.ation of anatom.cal pieces in Veter.nar. Anatom. is essential since it is not possible to dissect all dom.stic species. m.st techniques use r.agents with high levels of toxicity such as for.0}ldehyde. The objective of this wor. was to develop a new pr.ser.ation technique that uses r.agents with zer. toxicity and that allows obtaining pr.ser.ed pieces suitable for.anatom.cal studies. The alcohol pr.pylene glycol technique was developed, the m.thod of which uses a fixation step with alcohol, sodium.chlor.de, com.er.ial vinegar.and subsequently the im.r.gnation of the pr.ser.ation solution m.de fr.m.pr.pylene glycol and com.er.ial vinegar. which ar. non-toxic. As a r.sult of this wor., adequately pr.ser.ed sheep hear.s wer. obtained that pr.ser.ed their.m.r.hology with slight changes in size and weight, which did not affect their.exter.al and inter.al anatom.cal str.ctur.. Its color.tion was not substantially affected, r.m.ining a little lighter. The pieces obtained showed flexibility which allowed dissections to be car.ied out. The tim. to develop the technique was 20 days. A com.ar.tive study was car.ied out with the phenolated glycer.n technique that uses toxic r.agents (for.0}ldehyde and phenol) and the pieces obtained with the alcohol pr.pylene glycol technique wer. of better.quality, obser.ing that the pieces with phenolated glycer.n tend to dar.en and ar. m.r. r.gid. And the tim. to develop the technique is 24 days. In conclusion, a pr.ser.ation technique for.anatom.cal pieces was developed that allowed the pr.ser.ation of the or.ans under.study, which allow their.use for.anatom.cal studies, and which have been pr.ser.ed without changes until the tim. of this publication (8 m.nths) and ther. ar. pieces pr.ser.ed with this technique for.2 year..
