Genomic proofs give us the confidence to use exciting sires sooner! You can rest assured these bulls will deliver on their genetic promises because genomic testing provides an immediate reliability of around 70% for production, health and conformation traits.
You might be wondering, what are the different genomic sire options? Let’s break them down…
There are a few really special bulls – the type we easily recognize as outliers in the breed for a specific index or specific traits. Those are the type of bulls that a product development team will use as sires of sons.
Normally, those bulls would not be available until after their use for product development purposes. These bulls are very young, and don’t produce much semen. However, once we have a small amount of inventory on this sort of bull, they will be available as an Alta EDGE sire in North America. Only under signed and approved contract will herds be able to get the option of including these most elite of the elite sires in their breeding program.
Most sires begin their journey at Alta among this group of bulls, which is available only to our loyal Alta ADVANTAGE partner herds. Alta ADVANTAGE sires offer diverse trait specialties and elite rankings on many different customized genetic plans.
When a bull is first old enough to be collected, he simply won’t produce enough semen to be readily available to all farms around the globe. So while we work to build semen inventory, we give our committed Alta ADVANTAGE partner herds priority access to these elite, new sires that best fit their customized genetic plans.
Once a bull starts producing enough semen, he is added to the G-STAR sire list. Many new G-STAR bulls are readily available this proof round. Among these sires are a wide array of trait outliers, and high-ranking options to fit your genetic plan. Some of these bulls have even been released long enough to have proven information for sire fertility, so you can choose a balance of both high genetics and high fertility CONCEPT PLUS.
About a year after a bull is first released, we have actual, proven results for both sire fertility and calving ease. We gather this data, analyze the results, and award the FUTURE STAR designation to only the bulls with offspring already born, with results for proof of easy calvings, pregnancy check results that confirm they are above average for sire fertility. They also have calves born already, and their calving ease data shows them to be less than 8% for sire calving ease.
FUTURE STARS are the way to go if you want the benefits of elite genomics but prefer the added peace of mind of proven sire fertility and calving ease. You may give up some production and health as compared to the available G-STAR or ADVANTAGE only sires. But you can rest assured, knowing that you’re upping your chances for a both a pregnancy and a live calf from an easier calving. Because of the known calving ability, FUTURE STARS are often a good option to use on heifers.
About three years after a bull is first released, his earliest daughters will enter the milking string. Once there has been adequate time to collect milk test information from those daughters and/or analyze their actual conformation, the data is compiled by the Council on Dairy Cattle Breeding (CDCB) and Holstein Association USA. That information is then calculated into a sire’s first daughter proof.
From there, as more daughters begin their first lactation, their sire’s reliability continues to increase. PROVEN STAR sires are for those people who only prefer the highest reliability genetic options.
Compare the averages to see the progress
Now that you know the difference between each genomic sire option, and the progression a bull could make as he matures, compare the average genetic level of each group in the table below. You’ll see that the newest, Alta ADVANTAGE bulls have the highest genetic averages – especially for the money-making production and health traits. They’re followed by the G-STAR sires, and then by the more highly reliable FUTURE STARS. You’ll also see the comparison to daughter-proven sire averages, just for reference.
Despite the big difference in genetic averages between the genomic lists and daughter-proven averages, it’s important to note that every single bull atop our current daughter-proven list was once a part of the G-STAR and/or FUTURE STAR lists. This just shows how much, and how fast, we’re making genetic progress!
The track record is significant for our current genomic favorites. Each proof round, we see these genomic bulls deliver on their initial predictions, and eventually graduate to daughter-proven success.
A side-by-side comparison
We can take this comparison of genetic averages one step further. For the sake of simplicity, let’s use the 60-40-0 index to do a side-by-side comparison of our top daughter-proven sires and our top genomic-proven bulls.
Both lists have tremendous options to use. The top daughter-proven bulls are elite among their peers. In fact, AltaTOPSHOT would even rank #2 among our genomic-proven list. The rest widely recognized as popular options around the world. Yet, if we’re talking about using groups of bulls, instead of individual bulls, the genomic-proven average simply outpaces our daughter-proven options by a significant amount.

Have confidence in the right genetics for your dairy
With that in mind, have confidence that using a team of sires from the Alta ADVANTAGE, G-STAR or FUTURE STAR lists will help you meet your goals. And if you prefer the peace of mind from higher-reliability proven sires, you’ll certainly find the right bulls to fit your needs among that list.
The most important thing is to select a group of bulls that meet your customized goals for production, health and conformation – the type of bulls that will help you create more Alta 4-EVENT COWS. That is the key for you to drive progress to match your current situation and future goals.
