How to interpret rumination data and use daily rumination time for day-to-day decision-making.

Changing mating management on your dairy farm can offer benefits but comes with potential risks.

Using heat detection aids efficiently will help ensure a successful mating period on your dairy farm. There are different heat detection aids for cows, including tail paint, heat mount detectors, electronic heat detection, and vasectomised bulls.

Magnesium supplements can help prevent metabolic issues in your cows, such as milk fever and grass staggers. Start giving these supplements two to three weeks before calving and continue until spring pasture growth slows.

Lipids or fats, found in plant and animal products, are a key energy source in dairy cows' diet. They are typically low, between 2-6% of dry matter in pasture-based diets, as excess can harm rumen function and milk production.

Improving your herd's reproductive performance starts with understanding and adjusting the calving pattern. Late calving cows often have less recovery time and hence a lower chance of getting pregnant in the first six weeks.

Herd reproductive performance is a crucial factor in your dairy farming success. This page highlights the importance of accurate record-keeping, right from a calf's birth, to get a true picture of your herd's reproductive health.

The InCalf Fertility Focus Report evaluates your herd's reproductive performance and highlights areas to improve. Using your herd's data, it compares your performance against the top 25% of the industry.

Bull management involves ensuring the right number of healthy bulls for your herd, minimising stress and reducing injury risks. A correct ratio depends on your herd's size and percentage of pregnant cows.

Can your farm be both highly profitable and low in emissions intensity? New research from nearly 8,000 farms reveals how top-performing NZ dairy farms are achieving both and offer practical insights on how to achieve this on your farm.

In this episode of Talking Dairy, we explore the Resilient Pastures programme - a new research initiative tackling pasture persistence problems. Hear how farmers, scientists and funders are working together to find lasting, practical solutions.

Heat stress can negatively affect dairy cows in many ways. DairyNZ is researching methods of identifying when heat stress might occur to help farmers manage their herds and lessen its impact.

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

With NIWA’s prediction of an El Nino weather pattern and a high likelihood of a drier summer, how are farmers preparing? In this episode, we’re talking to Trevor Hamilton and Kevin McKinley who share their strategies for preparing for a dry summer.
