With over 20 years of research in immunogenetics and associated health benefits, immune response is highly effective and 30% heritable. This means that each generation bred to an Immunity+ sire is expected to reduce disease incidence by at least 5-10%!

"Working with our clients globally, we’re seeing the benefits of Immunity+ on herd health," says Paul Krueger, Semex Immunity+ Global Brand Manager. "There are other health solutions but none are like our exclusive Immunity+ and none are 30% heritable."

"In December, we increased our Immunity+ genetic offering with eight more sires ranking over +2600 GTPI, and 14 more over +2500 GTPI. It's a genetic solution for herd health with no genetic sacrifice."

In its elite Genomax™ lineup, Semex now has:

• 81 Genomax Immunity+ bulls over +2400 GTPI


• 51 Genomax Immunity+ bulls over +2500 GTPI


• 18 Genomax Immunity+ bulls over +2600 GTPI


• 14 Genomax Jersey Immunity+ bulls


• 8 Genomax Ayrshire Immunity+ bulls
