The MineralBoost team is often out and about at local events to make sure you are informed on mineral supplementation at key times throughout the year. We also like to make sure the benefits of adding measured minerals is clear.

Setting the Cows up for Peak Performance

Author: Taryn/Wednesday, 29 May 2019/Categories: Latest News

How cows are managed during the transition period (4 weeks either side of calving) has a major influence on milk production and fertility in the following lactation. In practice in New Zealand, there are 3 key stages of management which help to achieve good transition.

  • Management of ‘far off’ dry cows to ensure body condition score (BCS) of 5 (and 5.5 for heifers and 2nd calvers) by 3 weeks pre calving.
  • Management of the springer mob (cows up to 3 weeks pre-calving) to achieve good rumen adaptation, health and  feed efficiency, and to minimise metabolic and infectious diseases.
  • Management of the colostrum mob to encourage increased feed intake.

Body condition

  • Dry cows off around 60 days before calving at BCS 5 (or 5.5 for heifers) and feed a maintenance diet through the ‘far off’ dry period.
  • Where this is not achievable, work out how much weight needs to be gained to reach BCS 5 and how much time is needed to achieve this, to determine dry off date.
  • No weight gain should be expected in the first 1-2 weeks after dry off or the last 3 weeks before calving.
  • Make sure cows do not get too fat, particularly later calvers.

Springer mob

  • The diet for the springer cows should have sufficient energy and protein for maintenance plus late pregnancy
  • Include components of the milking cow ration to help the rumen adapt.
  • Rumen microbes take 7-10 days to adapt to a change in diet but rumen papillae (the folds on the inside of the rumen wall that increase surface area for nutrient absorption) can take 3-6 weeks to fully respond.
  • Starchy feeds and effective fibre are beneficial for papillae growth and rumen function.
  • All feeds must be clean and palatable - no spoilt or mouldy feed and no butyric silage.
  • Check the Dietary Cation Anion Balance (DCAB) of the diet and add anionic salts where needed (don’t hesitate to seek qualified advice if unsure).
  • Feed no calcium (except under guidance), plenty of magnesium and limited salt.
  • Feed a high quality trace mineral supplement to help immunity.


  • Introduce first calving heifers to the springer mob in plenty of time to allow them to adapt.
  • Even if feed is short, don’t leave them away until the last minute.
  • Ensure sufficient trough space and time if using a feed pad.

Colostrum mob

  • A starter drench (usually a blend of molasses, mono propylene glycol, protected fat and minerals) at calving can reduce the risk of metabolic issues and encourage feed intake.
  • If it is not practical to drench all cows at calving, focus on at risk cows (eg milk fever history, twins, older cows, difficult calving, highest yielders).
  • Feed the milkers’ ration, with extra limeflour where practical.
  • Feed the cleanest, freshest, best feeds.

Cow feedback

Ask the cows if you have got it right by observing cow condition (be honest and use the guide), grazing behaviour, rumen fill, cud chewing activity and dung consistency. While in the paddock, ensure there is plenty of clean water available.

Millions tune in watch start of fresh NZ milk sales to China through Alibaba – wow!!

Tuesday, 12 September 2017

Milk New Zealand managing director Terry Lee and agribusiness chief executive Justine Kidd launched their agreement to supply fresh milk into China at the company's farm just south of Hamilton.

Milk New Zealand's trade agreement with global online retailer Alibaba has been launched with millions of Chinese consumers tuning in to watch the event. The Chinese-owned company's Collins Road Farm is just south of Hamilton and its 29 New Zealand farms will supply Alibaba with fresh milk to be sold on its online platform.

Organisers of the launch rented a satellite facility for the day to enable it to be live streamed directly to China. In attendance were 10 of China's biggest social media influencers including Yuni and Joyce, who are known as the Chufei Churan twins in China.  The pair are considered the Chinese Kardashians with social media follower numbers larger than New Zealand's entire population. They and other influencers videoed the event and the farm directly to their followers in China.Save


FE Spore Counts High,  Water Treatment Is Not Enough

Spore Counts are on the rise again this week

Friday, 5 February 2016
Another week of warm weather sees spore counts increase in many regions over the North Island. 

It is important to monitor your own farms pasture spore counts every week. If spore counts are trending upwards 20, 000 spores / gram and weather conditions look favourable for sporulation you must implement Facial Eczema control and prevention strategies. 

Hauraki Plains have increased from 40, 000 to 150, 000 spores in the past week. Other areas that have increased dramatically throughout the week are Piako, Wanganui, Gisborne, Horowhenua & Wairarapa. 

It is not too late to implement your facial eczema management plan. MineralBoostG2 Zinc is registered with the ACVM as a veterinary medicine for the prevention of facial eczema and should be included in your next PKE or meal blend order, at 200gms per cow, per day.

Your facial eczema prevention should be well under way

Monday, 25 January 2016

As more regions are reported on we are seeing a dramatic lift in spore counts. Make sure that your facial eczema preventative programme is well underway and that you are using proven zinc products such as MineralBoostG2 Zinc. MineralBoostG2 Zinc is registered with the ACVM as a veterinary medicine for the prevention of facial eczema and should be included in your next PKE or meal blend order, at 200gms per cow, per day.


Gribbles first spore count report is out - take a look to see how your region could be affected

Tuesday, 19 January 2016

The first report from Gribbles for facial eczema has now arrived. Of special note is that there are already hot areas within certain regions.

Don’t take risks with your livestock.  Remember that 100 days at a count of 5,000 can be just a as damaging as a day at 500,000. The damage is cumulative and animals that are already sensitised earlier in the season or with previous liver damage of any cause are at greater risk when counts rise. Facial Eczema can be the biggest production killer on farms in the North Island and is very preventable.


Facial Eczema - Prevention is better than cure

Thursday, 26 November 2015

Most farmers associate Facial Eczema with peeling skin but this is just the tip of the iceberg as far as production losses are concerned. The main damage cause by sporidesmin, a mycotoxin produced by the fungus Pithomyces chartarum, occurs in the bile ducts of the liver. Extensive liver damage has been occurring for at least 2 weeks by the time signs of photosensitivity occur, and only about a tenth of the cows with liver damage will show any signs of photosensitivity. Facial Eczema can cost our dairy industry as much as $100 million in a high challenge year.
