What Is Immunity?

By Dr Steven Larmer, Semex Dairy Solutions Coordinator  In 2012 Semex launched the Immunity+® sire line, a group of sires selected to create cows that will be more resistant and resilient to disease challenges faced every day by commercial cows. The question is, how does Immunity+ work and what does having better immunity really mean? Answering this question is not simple. It can be a lack of clear information. Here lies an important role for vets, feed advisors and hoof trimmers. Also, there seems to be a tunnel vision among farmers and advisors that stops them from seeing the shortcomings of the barns. Thirdly, fear of investing money and time will be involved, even though good management doesn't have to cost more than bad management. Here also lies a task for advisors: ideally they can not only provide the right information, but they can also help clients change.   The immune system of all animals is complex, and there are many factors that impact how an animal is able to respond to different disease challenges. There are several branches to the immune system. The two branches of the immune system most important for resistance and resilience to disease are the innate and adaptive immune systems.    The innate immune system is responsible for detecting any threat to the individual and initiating an immune response. The adaptive immune system is then responsible for determining the best response depending on the specific pathogen that has invaded the cow. Going a little deeper there are two separate components of the adaptive immune system. The antibody mediated adaptive immune response, or AMIR, is responsible for responding primarily to bacteria. Bacteria generally cause the more common on farm diseases, usually the ones that can be more easily treated. These include diseases such as mastitis, metritis, and digital dermatitis. Cell mediated adaptive immune response, or CMIR, on the other hand is primarily responsible for ... Læs mere...

Semex & Immunity+ Lineup Grows Stronger In December

Five years ago Semex answered the call of dairymen everywhere who wanted to breed more healthy cows with the launch of Immunity+, offering a genetic solution to health traits. Since then dairymen worldwide have seen firsthand the results of breeding healthier herds through the Immunity+ lineup. Five years later, real world data backs up the decades of research Semex supported at the University of Guelph in Canada under the direction of Dr. Bonnie Mallard, BSc (Agr), MSc, PhD, Professor Immunogenetics, Department of Pathobiology. We have taken data from over 35 large commercial herds, and analyzed data from over 30,000 cows and 75,000 heifers, says Dr. Steven Larmer, Semex Dairy Solutions Coordinator. The results have been astonishing. Reductions in every major disease have been seen, and range anywhere from 5-20% reduction in animals sired by Immunity+ sires compared to all others. Mastitis, lameness and mortality saw especially large decreases in frequency. We hear from dairymen worldwide on a daily basis that their Immunity+ sired calves out-perform their herdmates, says Paul Krueger, Semex Vice President, US Sales & Global Marketing. Were actively selecting sires that offer both Immunity+ and the genetic package needed. And in December, this lineup is stronger than ever. 13 Holstein sires over +2700 GTPI 24 Holstein sires over +2600 GTPI 14 Holstein sires over +800 NM$ 10 sires over 1000 DWP$ 10 sires over +3.00 PTAT 41 sires under 7% SCE 32 Jersey Immunity+ sires 12 Ayrshire Immunity+ sires Semexs lineups are growing with both proven and Genomax sires reigning popular and valuable worldwide: 70 over +800 NM$ 54 over +2700 GTPI 45 over 1000 DWP$ 45 over +2000 PTAM 45 over +3.00 PTAT #1 PTAT Sire 0200HO10036 OH-River-SYC Byway #3 PTAT Sire 0200HO06480 Val-Bisson Doorman 10 of the Top 50 UK Type Merit Sires 0200HO10659 Stantons Applicable #1 UK Type Merit 0200HO10757 Westcoast Lighthouse #2 UK Type Merit 0200HO06267 ...

You add to this, their shallow, well-attached and veinatious udders with great feet & legs, and you get the complete package legends are made of. He makes the outstanding heifers that grow into special young cows that can win in the big league!”   Popular Genomax™ sire and Doorman son, 0200HO10146 Walnutlawn Solomon impressively sired six in the top 10 including the Junior Champion and 1st Summer Yearling, Kingsway Soloman Gorgeous.   Brian Carscadden, Semex Product Acquisition Specialist comments on Solomon, “Solomon’s family originates from Glen Drummond and was developed by Gen-I-Beq and Misty Springs. A Doorman from a tremendous Lavanguard, he’s definitely created a buzz as they begin to freshen, with shallow, well-attached udders and deep, open frames. They are very mobile and have a very correct slope from hooks to pins. There’s exciting days ahead for Solomon and I would not expect his popularity to wane anytime soon!”   Adding to the excitement surrounding this family, Semex is releasing 0200HO10992 Walnutlawn Sidekick, an ...

Semex's Millionaire Sire Fever Passes Away

Semex is saddened to announce that it’s 13th Millionaire Sire, 0200HO05592 Crackholm Fever, has passed away.   Debuting as the #2 Conformation sire in August 2010, Fever quickly became a stand-out in a sea of Goldwyn sons, and was dubbed the ‘Longevity King,’ as his proof only seemed to grow stronger as he added daughters from proof round to proof round. In August 2013, he was named the #1 second crop conformation sire, and with his great health traits and exceptional fertility he quickly became an international sensation, garnering his own searchable hashtag on social media… the #feverfanclub that is still active today.   "Fever was a truly exceptional bull,” says Paul Krueger, Vice President Global Marketing. “He stood out from all other Goldwyn sons because he offered high conformation along with desirable health traits. We’re extremely proud of the success he has had on dairies worldwide. Owners tell us that their Fevers are some of their most profitable and favorite cows they have. We’re very fortunate to have a limited quantity of Fever semen available, allowing dairymen to continue using this extremely popular Millionaire Sire.”

Thank You Dr Chesnais!

Dr Jacques Chesnais' last day at Semex will be Monday, July 31. Dr Chesnais, Semex Senior Geneticist, first joined Semex in 2003 and has led our genetics team on many fronts. Most importantly, he pioneered genomic studies with industry partners and supported the research behind many key Semex tools and programs. Semex thanks Dr Chesnais for his steadfast dedication and the entire Semex Family wishes him all the best in this next chapter of his life.     When asked about changes he has seen since 2003 he comments, "Without question it has been the introduction of genomic selection. One of the main reasons I joined Semex in 2003 was that I believed, based on the science available at the time, that genomic selection would revolutionize selection in dairy cattle."   "Semex was willing to let me start a research program to investigate this idea, even if at the time few people in the industry thought that genomics could have a large impact on dairy cattle breeding. The next year, in 2004, we started what was the first AI-driven research project in genomic selection in North America, in cooperation with the University of Guelph and Pyxis Genomics, based on 4,500 markers. By 2006, following the sequencing of the bovine genome, we were using 10,000 markers. Soon after, we realized we needed more markers and more bulls and became part of the USDA genomics project led by Curt Van Tassell, which used DNA from the Collaborative Dairy DNA repository (CDDR)."   "This led to North American genomic evaluations in 2008 on a research basis, and in 2009 on an official basis and the rest is now history."    Thank you Dr Chesnais and best wishes!
