In Argentina they were born first five genetically modified horses to the world. This achievement represents a breakthrough in the field of equine biotechnology and promises to have a significant impact on sectors such as agriculture, veterinary medicine and genetic improvement.
The technique used to obtain these horses is the CRISPR-Cas9an advanced method of gene editing that allows precise changes to be made to DNA. This system allows you to identify and cut specific RNA sequences, offering high precision in genetic manipulation.
After cutting the DNA, the body’s natural repair mechanisms allow the desired genetic sequences to be inserted or modified. In this case, Argentine scientists modified the MSTN gene, known for its function in regulating muscle growth. The goal was to improve the physical performance of horsesincreasing their muscle power and speed.
This project was carried out by the biotechnology company Kheiron SA, already famous for its progress in equine cloning. With the support of local capital, the company has applied gene editing to create equine specimens with enhanced characteristics, thus speeding up the selection process compared to traditional methods. This approach could allow high-performance animals to be obtained in just one generation.
Is it really the right way?
However, there is no shortage of concerns. The use of gene editing techniques such as CRISPR-Cas9 cannot help but raise ethical questions, especially in the context of sport and breeding. The possibility of genetically manipulating animals to improve their physical performance could pave the way for a form of “gene doping”, which may be difficult to regulate. The risk of abuse of these technologies is an issue that deserves attention.
Although scientific innovation is indisputable, it is essential to also consider the ethical and environmental implications of such practices. The genetic manipulation of animals brings with it issues regarding biodiversity and animal welfare.
It is important to ask whether the goal of improving the physical performance of horses justifies intervention on their genetic heritage. Rather than accelerate species improvement, we should perhaps concefocus on the conservation and respect of the natural characteristics of animalsavoiding transforming them into tools to satisfy human needs and profit.
