Dose Rates: make salt blocks freely available as required

• 20kg blocks – sheep, goats, camelids – 1 block per 50 head, 1 block should last +50 days, consumption 5-10g/head/day
• 20kg blocks – cattle, deer – 1 block per 10 head, 1 block should last +50 days, consumption 15-25g/head/day
• 2.5kg blocks – sheep, goats, camelids – 1 block per 10 head, 1 block should last +20 days, consumption 5-10g/head/day
• 2.5kg blocks – cattle, deer – 1 block per head, 1 block should last +75 days, consumption 15-25g/head/day

Warnings:

• For animal treatment only.
• Make sure animals have access to fresh water when feeding salt.
• Do not exceed the recommended dose rates.
• 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.

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

Weathering

All salt is soluble. Summit Salt Block formulations improve water shedding. Trials prove Summit Salt Blocks last nearly 4 times longer than rock salt and require twice as much rainfall before being broken down when exposed to weather elements.
