At Semex we know Beef production must increase from 60 million to 130 million tons by 2050 to feed our growing world, and it’s estimated 70% of this production will come from subtropical and tropical regions of the world. Therefore, Semex is excited to announce the expansion of its Progenesis Product Development Program to include the valuable tropical breed Nelore.     The Nelore breed is uniquely suited to tropical climates. It is extremely hardy, having both physical strength and an ability to thrive under harsher climates, it is heat and insect-resistant, easily converts poorer forages to beef, and has meat that is highly palatable being low calorie and lean with no compromise for taste.    Brazil leads the world with its Nelore breeding program, having the highest quality and largest populations, making it a natural home for the Progenesis Tropical Breed Program.     “Over 12 million doses of Nelore semen are sold in Brazil alone,” says Nelson Eduardo Ziehlsdorff, Semex Brazil General Manager. “With this new program, we will partner with local Nelore breeders to deliver the best bulls for Brazil and other tropical climates.”   “Semex continues to see unprecedented growth in our Nelore and Bos Indicus products in Brazil and around the world. This initiative will build on the great relationships Semex has with our genetic partners and drive future growth of genetic sales from this important market segment,” says Brad Sayles, Semex Chief Operating Officer.

Lactanet Canada and Semex Win the Prestigious Innovation in Climate Action Award

Partnerships are very much a part of the Canadian dairy scene that supports dairy farmers and the industry at large. Lactanet Canada and Semex have a long-standing synergy working collaboratively and last night received a prestigious Dairy Innovation Award: “Innovation in Climate Action”, from the International Dairy Federation (IDF).

Nominated by Dairy Farmers of Canada, Lactanet and Semex were recognized during the IDF World Dairy Summit in Chicago, Illinois, for developing Canada’s Methane Efficiency genetic evaluation. This is the world's first official genetic evaluation that helps dairy producers genetically select animals that will contribute to reduced methane emissions from dairy cattle, without impacting production levels.  


“As the dairy sector works together towards net-zero greenhouse gas emissions by 2050, we know the important role research and innovation plays along our shared path,” says David Wiens, President of Dairy Farmers of Canada (DFC). “The funding this initiative received from DFC in collaboration with other engaged partners, helped demonstrate the accuracy of predicting individual animal methane emissions. We are excited and honoured to be part of the future of dairy farming, and we thank the IDF Dairy Innovation Awards for recognizing the continuous efforts of dairy farmers in striving for a more sustainable future for everyone.” 

Lactanet’s Methane Efficiency genetic evaluation was launched in April 2023 after 10 years of research and development, led by the University of Guelph, using innovative technologies to evaluate and predict a cow’s methane production. This achievement is a cardinal piece of the dairy industry’s national strategy to reach net zero by 2050.


“Accelerating sustainable and innovative dairy management practices is important to our industry and we all have a role to play,” states Barbara Paquet, ... Læs mere...

The North American industry has identified a new Holstein genetic defect, Calf Recumbency, where an otherwise healthy calf cannot stand and survive, either at birth or within its first few weeks of life. Though the origin animal has yet to be confirmed, the oldest known suspected carrier is the bull SOUTHWIND. The disorder has primarily been transmitted through the sires ROBUST and SUPERSIRE. An industry position paper has been released by the National Association of Animal Breeders (NAAB), Council on Dairy Cattle Breeding (CDCB) and the Holstein Association USA. Click here to read.     Semex worked diligently with industry researchers to help identify this genetic defect. Semex recognized the urgency of this matter and for corrective measures to be put in place quickly to reduce and eventually eliminate this mutation. In so doing, Semex has worked aggressively with our lab partner Neogen to test all our sires as listed below. This list will be updated as new bulls are tested or released to market.     This development demonstrates the industry’s ability to not only discover debilitating disorders but also activate world-leading genetic researchers that use a comprehensive genomic database to untangle a complex disorder and quickly develop a diagnostic tool that proficiently addresses the problem.     Genetic recessives such as BL, BY, CVM and HCD have been identified in the past. In all cases, the industry responded quickly by identifying carriers and providing breeders with the tools that effectively minimize these disorders in the population. Calf Recumbency will be no different.     The industry is working on coding/labeling and plans to develop a haplotype test that effectively identifies recumbency without needing the mutation test. Semex is currently making changes to its OptiMate™ mating program, enabling its clients to proficiently breed around recumbency and reduce its potential impact.     Semex’s genomic testing ...

I takt med at samfundets og politisk kritik i stigende grad fokuserer på landbruget, introducerer Semex en genetisk løsning, der kan reducere metan-udledningen med 20-30% i 2050.   ”Ligesom med Immunity+ ® har vi arbejdet sammen med videnskabsmænd fra agroindustrien for at finde en genetisk løsning til at reducere metan-emissioner,” siger Dr.Michael Lohuis, Vice President Research & Innovation hos Semex. ”I mere end fem år har de canadiske mælkeregistre, nu under Lactanet, har mere end 13 millioner mælke-mid-infrarøde (MIR) spektroskopidata. Mere end 700.000 MIR-data fra første laktation blev analyseret af Lactanet-genetikere for at forudsige metan-emissioner for mælkeregistrerede køer i hele Canada. Resultaterne viste, at man kan reducere metan-udledningen væsentligt med genetisk selektion.”   I april 2023 vil Lactanet offentliggøre avlsværdier for metaneffektivitet, som landmænd kan bruge til at reducere kvægets metan udledning markant. For genomiske tyre er det 70 % pålideligt, og det anslås, at emissionerne kan reduceres med 20 – 30 % i 2050 alene gennem genetisk selektion.   Semex’s Elevate ® - brugere modtager automatisk et metan-indeks over alle genomisk testede hunkønsdyr. Derudover vil et indeks være tilgængeligt for Semex Holstein tyre fra april. Dette giver malkekvægsbedrifter en klar genetisk løsning og en hurtigere overgang til en besætning med lavt metanindhold.   ”Metan er et globalt problem,” siger Drew Sloan, Semex Vice President for Corporate Development. ”Faktisk vedtager de fleste udviklingslande love, der sigter mod nul udledning af drivhusgasser i 2050. Denne nye egenskab er en gamechanger. Nu er det tid til genetisk at teste din besætning med Elevate, hvilket giver dig mulighed for at ... Læs mere...
