A male set of chromosomes, female expressions, and no uncomfortable boar’s smell: That is the result of study that has been undertaken by researchers from the Institute for Livestock Genetics of the Friedrich-Loeffler-Institute at Mariensee. The results have been published now. In the study, gene-modified pigs have been generated that carry male genetic material in which a critical part of the Y-chromosome has been turned off. This part is important for the early embryonal sex determination. The result are animals that carry male genetic material but have female expressions.

This study shows that the typical uncomfortable boar’s smell can be avoided. In the future, no castration might have to be done. During the past year, EQAsce has done a lot of information-webinars due to a change in the German law – valid since the beginning of 2021. There has been high interest in this information. But considering the results of this new study, the whole branch can deal with a completely new perspective and alternative to the previous practice.
