If you're in charge of cattle or deer, you must meet legal obligations like registering your farm, tagging and registering your animals with approved RFID tags, and recording all animal movements within 48 hours.

When it comes to breeding more efficient cows, why is genetic gain so important and how can NZAEL’s online tools help? Join us as we talk about the latest in dairy genetics and animal evaluation.

Phosphorus (P) is an essential element for plant and animal growth but can harm the environment if not properly managed. There are good farming practices that can help minimise P loss and optimise farm productivity.

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%.

Genomics is the use of DNA to predict the future potential and profitability of dairy animals.

Inbreeding in cattle is when an animal's DNA is identical because it comes from a common ancestor on both parents' sides. This page explains how inbreeding coefficients estimate the expected degree of inbreeding, but these aren't always precise.

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.
