“We use a lot of sexed semen in our Jersey herd that we have had for 42 years, and 95% of the herd is VikingJersey. Using sexed semen allows us to achieve faster genetic progress in our herd. We use 90% sexed semen on all heifers, all year round. For the cows, we use 90% sexed semen from August to March.
The quality of the semen is very good; we have an 88% gender purity rate this year. For us, it is very profitable to use sexed semen, because we are able to sell surplus heifers. There is good availability of X-Vik sexed doses on the whole range of bulls that suit us very well.”
