What is short gestation length 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, SGL semen is replacing natural mating bulls across New Zealand farms thanks to its reliability and measurable results.

Why SGL?​

​

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

SGL 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 SGL semen strategically on later-calving cows to keep them aligned with the rest of the herd.​
