Summit Dairy Minerals – MultiMix and MagMix 25kg

Lack of sodium can be a production limiting issue.

It is easily fixed with salt.


The Dairy Mineral range is specifically designed for New Zealand pastoral dairy systems to provide an essential source of trace minerals (Se, Co, Zn, I, Cu) and magnesium, (Mg) with salt as a carrier. The formulations have been based on average daily mineral requirements for lactating cows. Summit Dairy MultiMix and MagMix can be fed in troughs or hoppers, on its own or combined with other feeds.

Summit Magmix™ is a loose mix of minerals and salt formulated to provide a supplementary source of sodium and magnesium to assist milk production in dairy cows and to aid in the prevention of grass staggers, particularly at times of increased magnesium requirements such as calving and lactation. Flavour boosted with molasses and edible meal for enhanced palatability.

Sodium and Dairy Production

Salt is lost to the cow in milk, urine, faeces, sweat and saliva. And it is not insignificant – a cow milking 20 litres/day can lose the equivalent of 35g of salt in the milk each day. Pasture can be low in sodium and bulk feeds are often deficient. The benefits of sodium supplementation have been demonstrated in NZ and overseas. A trial conducted near Rotorua by AgResearch in 1999-2000 supplemented cows with 35g/day salt and achieved a 12.8% lift in milk production. Milk yield responses occurred immediately and continued through the trial. At the time $1 spent on salt returned $33 in extra milk.

Animals have a strong appetite for salt but individual salt needs will vary. Factors influencing needs include:

  • Sodium and chloride levels in the pasture
  • Sodium and chloride levels in the water
  • The production cycle – growth, reproduction and lactation will increase requirements
  • Temperature/humidity – sweating will increase sodium requirements
  • Potassium levels in the diet – animals will try to balance high potassium feeds with additional salt to maintain fluid balance
  • Low sodium levels in bulk feeds
Summit Dairy Minerals are a cost effective way of supplementing essential minerals while providing the salt required to maintain milk production.
