Understand How the Research Was Conducted for the First Genetically Edited Calves to Be Born and What This Changes in Brazilian Livestock.
The future of Brazilian livestock has just taken a giant leap. In a historic milestone for the national agribusiness, the first genetically edited calves in Brazil have been born, opening a new era of innovation and sustainability.
This extraordinary achievement is the result of the cutting-edge Research Led by Embrapa Dairy Cattle, positioning the country at the forefront of global animal biotechnology, promising to transform productivity and herd health.
The First Genetically Edited Calves in Brazil: A Milestone in National Science
The arrival of the first genetically edited calves in Brazil represents an unprecedented advance for science and livestock.
-
The state that supplies Brazil with 600,000 tons of onions annually is seeing its own farmers go bankrupt one after another because no one pays a fair price for the product. The situation became so critical that the government had to urgently freeze debts to prevent a wave of bankruptcies in rural Santa Catarina.
-
The Brazilian export machine is breaking record after record, with billions entering the country every month. China buys everything Brazil produces, Europe increased its imports by almost 10%, and Brazilian ports received R$ 7.8 billion in investments to avoid collapsing under the brutal demand.
-
Experts warn that salinization already threatens 1.4 billion hectares of soil on the planet and could put another 1 billion at risk, with China, the United States, and Russia among the affected countries and productivity losses that can reach 70% in degraded agricultural areas.
-
The world’s largest soybean meal importer is rejecting shipments from South America due to an unauthorized gene. Prices have already soared almost 5% in a month on the Chicago Board of Trade, and Brazil is racing against time to avoid being blocked as well and losing its biggest buyer market.
Unlike transgenesis (which inserts genes from other species), genetic editing works through the precise alteration of existing genes in the animal’s DNA, allowing for the enhancement of traits in a much more targeted and efficient manner.
These pioneering calves are more than just a symbol of innovation; they are the realization of years of study and dedication. The genetic editing technique, known as CRISPR/Cas9, acts like a “molecular scissors” that cuts and pastes DNA, enabling the insertion, removal, or modification of specific genetic sequences.
This unprecedented control over the genome opens a range of possibilities for enhancing important traits for animal production and animal health.
The birth of these genetically edited calves in Brazil places the country in an elite group of nations capable of developing and applying this advanced technology, reinforcing Brazil’s position as a global agricultural power, now also in cutting-edge animal biotechnology.
Research Led by Embrapa Dairy Cattle: Scientific Leadership
The Research Led by Embrapa Dairy Cattle was the driving force behind this historic achievement.
The unit, located in Juiz de Fora (MG), is a benchmark in innovation for the dairy sector and has heavily invested in biotechnology. The project for genetically edited calves in Brazil is a testament to the technical and scientific capacity of Brazilian researchers.
The initial focus of the research with these calves is the enhancement of disease resistance and heat tolerance traits.
For example, genetic editing can confer greater resistance to diseases that cause significant economic losses for producers, such as mastitis or parasites.
Furthermore, the ability to develop calves that are more tolerant to high temperatures is crucial for livestock in tropical regions, where heat stress affects productivity and animal welfare.
Embrapa highlights that genetic editing technology is a powerful tool for:
- Accelerating Genetic Improvement: Allows for the introduction of desirable traits in less time than traditional breeding methods.
- Increasing Productivity: Results in healthier animals that produce more and of higher quality.
- Reducing the Use of Antibiotics and Medications: By creating animals more resistant to diseases, the need for medical interventions decreases, contributing to sustainability and reducing antimicrobial resistance.
- Improving Animal Welfare: Animals that are better adapted to the environment and resistant to diseases suffer less.
The Future of Livestock with Genetically Edited Calves
The birth of the first genetically edited calves in Brazil is just the beginning of a new era for livestock.
The research led by Embrapa Dairy Cattle paves the way for the development of more efficient, resilient, and sustainable herds, directly impacting meat and milk production.
This technology has the potential to:
- Ensure Food Security: Increase the supply of animal-derived food more efficiently and sustainably for a growing global population.
- Reduce Environmental Impact: More efficient and healthier animals may require fewer resources and generate less waste, contributing to more ecological livestock practices.
- Generate Added Value: Position Brazil as an exporter of advanced animal genetics and high-quality products.
It is important to emphasize that genetic editing is a precise technology that undergoes rigorous validation and regulation processes. The focus is always on safety and ethics, ensuring that these advances benefit society responsibly.
The first genetically edited calves in Brazil are, therefore, a symbol of a promising future, where science and technology work together to strengthen agribusiness and animal health in our country.
