LIC | Reproduction


Getting cows in calf quickly is important for driving profitability on farm, but it can be a real challenge. 6-week in-calf rate and empty rate are the dairy industry measures of herd reproductive performance.  Maximising 6 week in-calf rate drives a compact calving and more choice, allowing farmers to achieve:

  • Better quality cows in the herd 
  • More calves on the ground
  • More milk in the vat 
  • More money in the bank

The LIC Reproduction Solutions Team

LIC’s Reproduction Solutions Team (the ‘repro’ team) exists to help LIC’s farmer customers improve their herd’s reproductive performance and to lift New Zealand’s national 6-week in-calf rate. 

Our team works with farmers and their rural advisor networks to:

  • Raise awareness of dairy herd reproduction principles
  • Focus on the areas of biggest impact in dairy herds 
  • Develop tools and software to assist with herd information analysis, planners and resources for best practice reproduction practices
  • Benchmark and report industry reproductive performance trends
  • Assist farmers to access information through our 6 Week Challenge website, the LIC website and at seminars and industry events. 

We work with farmers' advisors, assisting them with information and interpretation of reports on MINDA™, so they can assists farmers to make good decisions on farm.



Farmers that have engaged with the 6 Week Challenge and the Repro Team are focused on their herd fertility and have achieved higher levels of reproductive performance compared to farmers who have not.
