The power of the genome
GENOME
What is it?
The genome is the complete set of genetic information present in an animal’s DNA. From a small biological sample, it is possible to perform a genomic test that identifies thousands of genetic markers associated with important traits.
- This information allows for highly reliable
- estimates of an animal’s potential for traits such as:
- Milk production
- Fat and protein content
- Fertility
- Productive longevity
- Udder health (mastitis)
- Feed efficiency
- Conformation
What is the genomic test used for on the farm?
The main objective of genomics is to accelerate genetic improvement of the herd. Traditionally, producers had to wait years — until a cow had several lactations — to evaluate its actual performance. With genomics, this evaluation can be done in the first months of life, enabling faster and more strategic decision-making.
Among the main benefits are:
More accurate selection of the best females Producers can identify which heifers have the highest genetic potential for production and reproduction.
Better use of reproductive technologies The best females can be directed to in vitro fertilization (IVF) or embryo production, rapidly multiplying superior genetics.
Strategic culling Animals with lower genetic merit can be culled earlier or redirected to other production systems.
Increased profitability Over generations, genomics-based selection results in more productive, efficient, and healthier herds.
A new era for dairy farming Genomics represents a true revolution in animal breeding. By transforming DNA into practical information for decision-making, it enables producers to reduce the time required for genetic selection and increase the efficiency of production systems. In practice, this means making decisions based on real data to evolve the herd in a faster and more strategic way.
