Haplotype & genomic reliability updates

Based on new findings from the Council on Dairy Cattle Breeding (CDCB), one new haplotype will be added, and two others removed, starting with December 2018 proofs. Alta Bull Search and Alta GPS will be programmed according to this new information.

A new Holstein haplotype, HH6, was recently identified in France, and is currently found in about 0.5% of animals in the US Holstein population. Mating two HH6 carriers is expected to yield a 7%-11% drop in conception rate.

Further research into the JH2 haplotype in Jerseys and the BH1 haplotype in Brown Swiss showed no significant fertility losses on matings between carriers. This, paired with the fact that researchers could find no causative mutation on these two haplotypes, means they will no longer be reported.

Gene test advancements

In addition to new and discontinued haplotypes, the reported haplotypes are also gaining accuracy. PEAK Geneticist, Doug Bjelland, compares the improved accuracy of haplotypes to locating a house on a map. The previous way of recognizing haplotypes essentially showed us which street a house is located on. Now, because of gene test advancements for causative mutations to determine haplotypes, we know exactly where on that street a house is located.

Upgraded genomic reliability

Improved genomic accuracy also extends beyond the gene test. Researchers are now using an 80k SNP chip. This means they are using nearly 80,000 markers on the genome, up from the previous 60,000 used since 2014.

The additional markers, combined with a new reference genome, give genomic predictions about a 1% – 2% improvement in reliability.

What does this mean for you?

We want to keep you up-to-date on the newest genetic findings. Updates on haplotypes and genomic accuracy are one part of that. Because the haplotype updates will be accounted for within the AltaGPS program, you can have confidence that potential carriers of two bulls will not be mated together. That means your clients are protected from any potential fertility losses that could result in mating two carriers of any given haplotype.

Improved genomic accuracy should give you, and your clients, even more confidence that genomics and genetics continue to advance at more rapid rate. It’s as important now as it ever has been, to ensure your clients select genetics according to their customized genetic plan so the progress they make aligns with their current situation and future goals.

Not all genomic sires are created equal

Genomic proofs give us the confidence to use exciting sires sooner! Be assured that these bulls will deliver on their genetic promises, since genomic testing provides an immediate reliability of nearly 70% for production, health and conformation traits.

You might be wondering, what are the different genomic sire options? Let’s break them down…

Alta ADVANTAGE

Our 23 newest bulls are available only to our Alta ADVANTAGE partner herds. These Alta ADVANTAGE only sires offer diverse trait specialties and elite rankings on many customized genetic plans.

New, young bulls simply don’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 loyal Alta ADVANTAGE partner herds priority access to these elite, new sires that best fit their customized genetic plans.

G-STARS

Once a bull has made enough semen he is added to the G-STAR sire list. With 30 new G-STAR bulls this proof round, these sires are readily available to everyone. This groups includes a wide array of outliers for various production, health and type traits. From this elite list, you can find a great selection of bulls to fit your genetic plan.

FUTURE STARS

About a year after a bull is first released, we know 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 that prove themselves above average for sire fertility and less than 8% for sire calving ease and sire stillbirth.

This proof round, 13 bulls earned their FUTURE STAR status. This means they gained enough pregnancy check observations to prove their high fertility CONCEPT PLUS status. Plus, they have enough offspring born to prove their easy calvings.

FUTURE STARS are the way to go if you want the benefits of elite genomics, but prefer the added reliability 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 gain peace of mind knowing that you’re upping your chances for a pregnancy and a live calf resulting from an easier calving.

Because of the known calving ability, FUTURE STARS are ideal options to use on heifers.

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, followed by the G-STAR sires, and then by the more highly reliable FUTURE STARS.

It’s also important to note that every single bull atop our current daughter-proven list was once a part of the genomic-proven lists. 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.

With that in mind, have confidence to use a team of sires from the Alta ADVANTAGE, G-STAR or FUTURE STAR lists. You’ll optimize future profitability by selecting a group of bulls that meet your customized goals for production, health and conformation.
