SexedULTRA 4M is a product designed to double the amount of female sperm cells in an average sexed semen straw, giving a product that rivals conventional semen on conception rates with many UK farmers achieving this.

A tool employed by Cogent, the sexed semen calculator, estimates the difference in profit when switching to a sexed semen strategy. In many cases the cost benefit to using this strategy adds a worth of up to 1ppl in calf revenue with 70% beef calves born in the herd, an increase from 50% in a conventional semen strategy.

With a genetic gain in the female replacements, an additional £11.60 per lactation per year can be achieved.
