Semex Launches Repromax, World's First International Fertility Evaluation

Semex is proud to introduce Repromax, its lineup of highly fertile sires selected to increase profitability by reducing costly days open.

Semex scientists have carefully reviewed fertility information from over 3,000 bulls to determine which Semex sires were most effective at getting cows bred, and have designated these fertility specialists as Repromax sires. Repromax is unique as it takes into account international information from numerous countries and sources, with the goal of improving the fertility performance of cows, and makes Repromax the world's first international fertility evaluation.

"The Repromax sire list combines the best fertility information from all sources," says Senior Geneticist, Dr. Jacques P. Chesnais.

"We've taken into consideration the well-known and established forms of fertility analysis, Estimated Relative Conception Rate (ERCR), Agri-Tech Analysis (ATA), as well as Canada's Non-Return Rate data to determine which Semex sires are fertility specialists, and we have designated these sires as Semex Repromax sires."

"The Canadian information is particularly important because it is based entirely on extensive professional technician data. This increases the reliability of the fertility evaluation and makes designated Repromax sires a powerful tool for dairymen."

Pregnancies are a valuable commodity on the dairy and Repromax sires work to make sure dairymen have the best product to get cows in calf, everytime.

"Our Repromax sires represent the best of the best," says Pierre Laliberté, Senior Vice-President, Global Genetic Programs/Operations.

"Semex's Repromax sires are highly proven, reliable bulls from our lineup that are proven to be high fertility sires, with no genetic sacrifices for quality. We believe dairymen should have the best of both worlds... cows in calf and genetic improvement in their herds."

Semex's Repromax sires are available from our Holstein and Jersey lineups and are designated with the "Repromax" logo. Click here for more information and a listing of bulls.
