Our Dairy Sires

Repromix is the trade name for any semen cocktail marketed by The Semex Alliance in collaboration with CIAQ and its partners in order to improve conception rate. Also known as heterospermic semen, these products contain the semen of three different sires on one straw and this combination is known to improve conception rates.

Let us recall that the primary goal for the use of heterospermic semen is first and foremost to increase the probability of getting problem cows “in calf” and it is in no way the miracle solution to fertility problems.

Here are the Repromix cocktails presently available :                                           List of all cocktails
