The DairyNZ-led, Low N Systems research programme investigates stacking (or combining) management strategies and mitigation technologies on dairy farms to deliver reductions in nitrate leaching of over 40%.

A breeding value is an estimate of an animal's genetic merit for a particular trait. Using breeding values to select cows and bulls to be the parents of the next generation is the most effective way to achieve genetic improvement.

Cow performance measurement lets you identify the most and least productive cows in your herd.

Effective cow data recording and performance measurement on your farm can make the difference in breeding decisions.

This page covers the concept of a base cow. Breeding Worth (BW) and Breeding Values (BV) are presented as the difference between an animal’s genetic merit and the average genetic merit of the 'base cows’.

This page covers the concept of genetic reliability, highlighting the confidence in an animal's breeding value and worth.

Senior Freshwater Ecologist

A new multi-year programme of work, led by AgResearch and jointly delivered by DairyNZ, is working with farmers to understand and reduce E. coli losses into waterways.

Read more about how farmers and catchment groups can now use state-of-the-art monitoring that detects fish, insects, microbes, aquatic plants, terrestrial plants, and even birds from their genetic material being present in stream water.

Fish need to move up and down waterways to feed, breed, and migrate between the sea and freshwater to complete their life cycle. Anything that stops fish movements is called a ‘fish passage barrier’.

Selecting the right cultivar for your farm remains just as important as ever. Use this page to make informed decisions when choosing ryegrass cultivars for pasture renovation.

DairyNZ’s subsidiary NZAEL (New Zealand Animal Evaluation Limited) has recently made a new fertility trait update – in this episode we’ll discuss what this change will mean and how it will benefit farmers.
