Semex scientists have gathered Sire Conception Rates (SCR), ATA and Non-Return data to develop the worlds first international fertility evaluation. Known as Repromax sires,these sires are Semexs highest-ranked fertility sires. Listed to the left, Repromax sires are highly reliable bulls proven to be high fertility sires, with no genetic sacrifices. These bulls improve the fertility performance of cows and increase your profitability, representing the best of the best, with no genetic sacrifices.

With dozens of numbers to analyze and problems to solve in a day, dairymen are looking to simplify processes and find easy solutions to their dairys problems.

The issue of conception and getting cows in calf is no exception. Measuring conception on farm is generally focused on one or more of the following three measures: pregnancy rate; number of days open; or number of inseminations per conception. The common denominator in each of these measures is that the dairyman needs to reduce the number of days the cow is open to increase his overall profitability.

How Much Does A Day Open Cost?

This impact may be greater than we think. A 2006 University of Florida study shows that this cost varies between $3.20 and $5.40/day and increases with average days open. These numbers take into account things like the value of the milk the cow would have produced, plus the value of her calf, as well as other concerns. Therefore if the average cost per extra day open is $4.50 and if one cow stays open 20 days longer than she should have, that dairy loses $90 on just that one cow alone.

On a 100-cow dairy this effect is tremendous and can cost the dairy an additional $9,000 in reduced profitability. Subsequently, larger herds feel this economic loss even greater.

Semexs Solution
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 worlds first international fertility evaluation.

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

"Weve taken into consideration the well-known and established forms of fertility analysis, Sire Conception Rate (SCR), Agri-Tech Analysis (ATA), as well as Canadas 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 Laliberte, Senior Vice-President, Global Genetic Programs/Operations.

"Semexs 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."
