What is short gestation semen?
Get access to carefully selected bulls proven to shorten the average gestation length of calves, without compromising calf health or cow performance while banking extra days in milk!
Proven in New Zealand’s unique conditions, short gestation semen is replacing natural mating bulls across New Zealand farms thanks to its reliability and measurable results.
Why SG?
Don’t let a missed heat throw your calving spread out, and don’t rely on a natural mating bull to get the job done.
Get shorter gestations
SG calves typically arrive 7–10 days earlier than average, giving cows more time to recover before mating.
Tighten your calving spread
Shorten the tail end of calving and reduce the number of late-calving cows in the herd.
Healthier cows at mating
More recovery time means better submission rates, higher conception, and stronger reproductive performance.
Flexible Breeding Strategy
Use SG semen strategically on later-calving cows to keep them aligned with the rest of the herd.
