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.

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.

Animal feed can affect animal health, milk quality and food safety, and the source of dairy products can be important to buyers and consumers. That’s why it’s important when buying and selling feed, it can be traced to its origin.

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.

Disbudding is the process of removing a calf's horns between one to six weeks old. This prevents injuries to both the farm team and other animals.

Clusters in dairy milking are a set of components that include a claw and four fully assembled cups. Selecting the right clusters and setting them up correctly will increase milking efficiency and improve animal health.

Sodium is vital for dairy cows, aiding in water balance and nerve and muscle function. It's expelled routinely and needs replacing. This page discusses how certain regions, like the Central Plateau pumice soils, can be deficient in sodium.

Bovine viral diarrhoea (BVD) is a widespread disease impacting around 80% of New Zealand's dairy and beef herds, causing losses in reproduction, increased disease, and reduced growth and milk production.

Apart from milk culture, individual cow somatic cell counts (ICSCCs) are the best method for determining whether cows have subclinical mastitis.

Dead stock management is the process of dealing with farm animal fatalities. It is important to appropriately dispose of carcasses to avoid spreading diseases, contaminating water, and harming the dairy industry's public image.
