Repromix is a semen cocktail of high fertility sires.  This combination of pooled semen has proven to increase conception rates by 6% above the control and when used on problem cows (those defined as fourth service and over), the fertility increase ranged from 3% – 6.6%.

Current studies on close to 1000 calvings show that nearly two-thirds of the resulting calves are Holstein when mated to a Holstein cow.
