RePRO BI genomic testing for US beef herds
Know more about the genetics behind your herd.
RePRO BI turns a simple tail hair sample into insights about your cattle's genetic potential. Understand traits linked to reproduction, growth and adaptation, and make more informed decisions about the bulls you use and the heifers you keep.
- Free tail hair sample cards
- Genomic breeding values across eight traits
- A team to help you put the results to work
Why genomic testing
See further than the pasture or the paperwork.
You know your cattle. Genomic testing adds another layer of information, helping you understand an animal's genetic potential before all of its traits are visible. It's a practical way to support the decisions you make about the next generation.
Eight traits. One genomic picture.
RePRO BI provides genomic breeding values for tropically-infused cattle across eight traits that shape how your animals breed, grow and cope with the conditions they live in.
Reproduction
Age at puberty
How early heifers are likely to reach puberty - a key factor in getting them bred on time.
Ability to conceive while lactating
The genetic likelihood a cow conceives within the first 4 months while raising a calf.
Growth and body
Weight
Genetic potential for body weight.
Hip height
Genetic potential for frame size.
Body condition score
The genetic tendency to carry and hold condition.
Adaptation and handling
Fly-strike incidence
Genetic susceptibility to fly strike.
Tick burden
The genetic tendency to carry lighter or heavier tick loads.
Temperament
The genetic tendency toward calmer, easier-handling cattle.
Which traits matter most, and how to read them, depends on your herd, your environment and your breeding goals. Running a particular breed or crossbred cattle? Talk to our team about whether RePRO BI is a good fit for your operation.

What's a genomic breeding value?
A genomic breeding value, or GBV, is a DNA-informed prediction of an animal's genetic potential for a particular trait. It also provides insight into the genetics that animal may pass on to its offspring.
GBVs help you compare animals and add another layer of information to your breeding decisions.
The GBV
Each animal receives a GBV for every trait: a prediction of its genetic potential, based on its DNA.
The ranking
See how an animal compares with the reference population used for the evaluation.
A GBV predicts genetic potential; it doesn't guarantee how an individual animal will perform. Environment, nutrition and management all play their part — which is why GBVs work best alongside your own eye, your records and your experience.
How it works
From tail hair to herd insight.
Four simple steps, starting with a tail hair sample from each animal you want to test.
Using your results
Put the information to work.
Bulls
Use genomic insights alongside physical assessment and other available information when you're comparing and selecting bulls.
Heifers
Understand the genetic strengths and opportunities within a group of replacement heifers, to help inform future selection and bull-buying decisions.
Advanced reproduction
Use genetic insights to help assess animals being considered for AI or embryo transfer programs, where the genetics you select can have an amplified influence on your herd.
Your results
What results will I receive?
Your RePRO BI results include:
- Genomic breeding values (GBVs) for all eight traits
- A ranking for each trait against the reference population
- A whole-group view of how your animals rank, trait by trait
- Breed composition
- Parentage
- Horn/Poll status
