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. “We’re actively selecting sires that offer both Immunity+ and the genetic package needed. And in December, this lineup is stronger than ever.”
