Summit Twinlix Salt Block 2.5kg and General Multimineral Salt Mix are suitable for horses and all other animal classes.

Summit TwinLix Salt BlockSummit TwinLix Salt Block.  Common salt (sodium chloride) is an essential constituent of an animals diet. Summit TwinLix Salt Block provides essential trace minerals (Cu, Zn, Co, I, Se) with salt as a carrier. The blocks can be used all year round with all stock classes except Texel sheep (as copper supplements can be toxic to Texel’s). TwinLix are sold in a convenient carry pack of 2 x 2.5kg blocks.


Summit General Multimineral Salt MixSummit General Multimineral Salt Mix provides essential salt with additional trace minerals (Cu, Zn, Co, I, Se) in a convenient loose mix that can be added to feeds. The loose mix can be used all year round with all stock classes except Texel sheep (as copper supplements can be toxic to Texel’s).

  • For animal treatment only.
  • Make sure animals have access to fresh water when feeding salt.

  • Do not use at the same time as any other selenised fertilizer prill or product without consulting a veterinarian.
  • Do not use with other copper supplements, including compound feeds, especially with young animals, without consulting a veterinarian.

Sodium and Production

Salt is lost 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.

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 Salt Blocks are a cost effective way of supplementing essential minerals while providing the salt required to maintain production and health.

Summit recommends:

  • Salt in some form should be available at all times all year around
  • Salt blocks should be available at all times when grazing Lucerne
  • More salt is available to lactating, young and growing animals
  • More salt is available when feeding fibrous feeds
  • Salt blocks should be available when grazing pasture recently fertilized with potassium


The following minerals are used in the Summit Salt Block range:

MineralFunctionDeficiency Symptoms
Calcium, CaComponent of bones and teeth. Required for nerve and muscle functionSevere growth stunting. Dental issues
Magnesium, MgRequired by enzymes/hormones and for the nervous systemGrass staggers, milk fever
Sodium, NaMaintains fluid balance, required for nerve function, maintains pH in the rumenReduced appetite, abnormal licking, reduced production
Copper, CuBone growth, pigmentation, enzymesLameness, illthrift, faded coat, poor conception rates
Selenium, SeImportant in the production of anti-oxidant and functioning of the immune systemIllthrift, diarrhoea, abortion, retained placenta, white muscle disease in lambs
Cobalt, CoRequired for vitamin B12 production, which is important for protein metabolismIllthrift, loss of appetite, reduced milk production
Iodine, IEssential for thyroid function which controls development and metabolismEnlarged thyroid, low milk production, low reproductive efficiency, lamb mortality
Zinc, ZnEssential for enzyme systems, immunity and hoof healthReduced appetite, low growth rates; wool, hoof and horn weakness
