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.

Early preparation of your winter grazing paddocks minimises sediment loss and movement. Use back fences and portable troughs to reduce soil damage by limiting unnecessary cow movement.

Breeding Worth (BW) is an index that ranks cows and bulls on their ability to breed profitable, efficient replacements. This page explains how BW is used to create herds resilient to changes and disease, therefore increasing farm profits.

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 tool estimates the latest date to dry cows off to ensure they meet BCS targets at calving.

Backing gates are tools used in the dairy yard to improve cow flow into the dairy, leading to more efficient milking. Moving the gate little and often takes up space in the yard, while still providing cows enough room is important.

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.

Once-a-day (OAD) milking is the practice of milking cows only once during a 24-hour period. This page covers the reasons and options for implementing OAD milking on your farm.

Trace elements, including cobalt, copper, iodine, selenium, and zinc, play a vital role in dairy cow nutrition. Your cows need these elements for functions like growth, reproduction, and milk production.

The page focuses on the importance of well-designed and maintained intersections between the yard and track on a dairy farm.

Copper deficiency in cattle, common during winter/early spring or in fast-growing calves over six months, can lead to issues like weight loss, reduced milk yields, reproductive problems, and anaemia in cows.

Carbohydrates, forming about 75% of plant dry matter, provide the major energy source for dairy cows and aid in milk glucose and fat production.

Pregnancy testing is key in managing your dairy herd. It tells you which cows are pregnant and their conception time, which helps you to plan effectively.

Salmonellosis is the most common disease associated with acute diarrhoea in adult dairy cows. Salmonella bacteria from cattle can also be transferred to humans, causing significant illness.

Giant buttercup, one of 14 weedy Ranunculus species in New Zealand, is harmful to dairy pastures because cows find it distasteful due to its toxin, protoanemonin. This weed spreads across dairy farms, damaging pasture quality.

Body Condition Scoring (BCS) is a method to monitor dairy cow health and productivity. This page provides a guide on how to carry out BCS, highlighting specific body parts to check, including the backbone, ribs, hip bones, and more.

Early detection of clinical mastitis is key to protecting milk quality and cow health. Check regularly for signs such as, heat, swelling, pain in the udder, and changes in the milk. Learn how to recognise the signs and take appropriate action.
