LIC Reports Record Six-Week In-Calf Rate for Dairy Herds
New season data from LIC shows a strong reproductive performance for the 2025-26 season, with a lift in key metrics compared to last season.
To help ensure a smooth spring mating period for farmers, a Cessna plane was used by LIC to deliver around 3,300 straws of semen between Timaru and Ashburton.
An additional 500 semen straws have been delivered via helicopter to affected farms on the West Coast. This helicopter delivery also included consumables needed by AB technicians to be able to do their jobs.
In a few cases, LIC’s AB technicians have been able to access cut-off farms via tractor.
Around three out of four dairy cows mated to AB in New Zealand are from LIC’s bull semen.
LIC’s National Artificial Breeding Manager David Hale says LIC understands the importance of delivering semen to all farms on schedule, regardless of weather conditions.
“The dairy cow cycle takes roughly between 18-24 days. If insemination doesn’t occur at the right time during that cycle, it means a three week wait until the cow is in heat again. This three week loss can have a number of negative flow-on effects for farmers, including the potential loss of three weeks’ worth of milk supply and an impact on calving periods the following year.”
“This is why LIC is working hard to ensure semen delivery is not impacted by the adverse weather conditions.”
LIC took a similar approach during the Kaikoura earthquake, with semen straws successfully flown to affected farms.
LIC dispatches and delivers around five million fresh semen straws and 1 million frozen semen straws each year from September through to Christmas.
The co-op’s 840 national artificial breeding technicians, supported by an additional 300 support staff, inseminate up to 100,000 cows each day during peak mating season. This equates to around 4.6 million inseminations performed by LIC each spring. Close to half of LIC’S AB technicians are farmers in their own right.
Colin Corney, LIC’s National Artificial Breeding Field Operations Manager, says affected farmers are doing an amazing job at looking out for each other and that there is a great support network.
“We are pleased to see farmers helping each other get through the wild weather. LIC will continue to deliver to flood-affected farms, unless it is too dangerous to do so.”
