1. Feeding synthetic zeolite pre-calving reduces milk fever

    A series of DairyNZ-led experiments have confirmed that supplementing cows with synthetic zeolite for two to three weeks pre-calving reduces the risk of milk fever in pasture-based systems.

  2. New traits to improve genetic merit for fertility

    The Fertility Breeding Value (BV) has led to gradual improvements in genetic merit for fertility. Under “Pillars of New Dairy System”, we aim to increase the accuracy of the Fertility BV to accelerate genetic improvement in fertility.

  3. Investing your levy to lift pasture performance

    DairyNZ's levy-funded projects focus on reducing dairying's environmental effects, while improving pasture dry matter yield, quality and persistence.

  4. Genetics and liveweight gain influence heifer puberty timing

    DairyNZ’s latest research indicates an ‘age at puberty’ trait has potential to increase the rate of genetic improvement in cow fertility.

  5. Accurate records breed success

    Are the heifers you choose to keep the ones you think they are?

  6. Can genetics help to reduce nitrogen leaching?

    DairyNZ is about to start on-farm research that aims to breed cattle with a lower nitrogen footprint.

  7. Economic values and why they matter

    The economic values used to calculate Breeding Worth have been updated to reflect world market changes.

  8. Breeding resilience pays off

    Southland farmers Simon and Mo Topham have always taken genetics seriously, but especially so when milk prices took a dive in 2014/15.
