Artificial breeding

Bull teams

Breed for success with our Premier Sires teams and Alpha bulls to see which of New Zealand's top bulls suit your herd.

Premier Sires®

Increase your herd’s genetic value with Premier Sires, a cost-effective and convenient way to mate your herd with New Zealand’s top bulls.

Alpha®

Breed for success with Alpha. Hand-pick highly ranked sires that meet your breeding criteria. Our bull genetics suit any farming systems including once-a-day, high input and A2.

Sexed Semen

Achieve an average of 90% gender accuracy with sexed semen.

A2 bulls

Meet the growing demand for A2/A2 milk by using our A2 bull team to breed A2/A2 cows.

Beef bulls and packs

Take advantage of the growing demand for dairy-beef calves and reduce your bobby numbers with our individual beef bulls and No Choice beef packs in a range of breeds.

Short gestation length semen

Boost profits with a shorter calving period and more days in milk. Our teams of selectively bred bulls will reduce gestation length by up to 10 days.

Genomic Wealth

We’ve been investing in genomics since the 1990s with a focus on increasing the rate of genetic gain in New Zealand dairy animals.

Sire Proving Scheme

Our Sire Proving Scheme is a rigorous, four-year programme that has been producing genetically superior bulls since 1961.

Organic semen

Breed organic dairy cows using our BioGro New Zealand certified semen, which is suitable for organic dairy farms.

Hall of Fame

The Hall of Fame is exclusively reserved for animals whose achievements have had, and will continue to have, a profound influence on the profitability of New Zealand’s dairy farmers and in-turn, the economy.

Crossbreeding with KiwiCross®

Get the best traits from the two main dairy breeds with our KiwiCross bulls.

Jersey Future

Get early access to promising young Jersey bulls and protect the breed’s future.

Inbreeding and recessive genes

Inbred animals are less productive and more likely to have genetic disorders. We can help you keep inbreeding at acceptable levels.

Breeding Worth calculator

Calculate your herd’s Breeding Worth (BW) to get a good indication of how well your animals performed this season.

DIY insemination

Learn to do your own insemination with one of our DIY inseminator training courses.

AB Facility Standards

Providing secure, appropriate AB facilities keeps our AB Technicians safe and gives them the best opportunity to get your cows in-calf when first presented.

Pre-mating AB tech visits

An AB pre-run is where your LIC AB tech meets with you on-farm to go through the details of your mating plan.

Artificial breeding technician service

Reduce your workload by letting our artificial breeding technicians inseminate your herd for you.

Train as an AB Technician

We train more than 100 new AB technicians every year. You’ll need to complete a two-week training course, then spend a year as an apprentice, working alongside an experienced technician, before you can start working on your own.
