Yellow Cap

Help combat grass tetany

Magnesium is important for all major muscles such as heart, rumen and uterus in ruminants.

The Yellow Cap product contains the unique 3 in 1 Beachport formulation but specifically targets increasing magnesium levels in livestock to help combat grass tetany, milk fever and improves overall muscle function.

Dosed once every 3 weeks, Yellow Cap high magnesium helps improve the health and performance of livestock at times when increased magnesium is required.

Benefits of Yellow Cap

  • Application flexibility – can be used in water supply or mixed with feed.
  • Includes trace elements with high magnesium for times when grass tetany is most prevalent.
  • Helps to improve overall muscle function.
  • High amino acid content (the building blocks of protein.)
  • Aids in improving calving/lambing ease.
  • Natural electrolytes for increased absorption and retention.
  • Kelp / Seagrass extract with over 90 different natural nutrients are included for overall health.
  • 3-year shelf life.

Application Methods

All Beachport Liquid Minerals products are designed for ease of use and flexibility to suit your program. The simplest and most effective method for the Yellow Cap product is via the water trough using a Beachport Dispenser, but it can be also used via a water tank, mixed with hay or through an inline system.

See below for further information on each application method.


  • Work out how many stock on water point: e.g. 200 breeders x 25mls = 5Ltrs. Treat 3 weekly to keep magnesium levels elevated.
  • Measure 5 litres of Beachport Liquid Minerals Yellow Cap product into a clean, empty 10ltr drum.
  • Screw the Beachport Dispenser tightly onto the top of the drum.
  • Ensure the trough has been cleaned thoroughly prior to placing the floating drum and dispenser into the water to prevent the inlet on the dispenser blocking when water is being sucked back into the drum.
  • Drop the drum with dispenser into the trough, it will automatically right itself into the correct position with the stainless steel dispenser under water.
  • Let the drum move freely around the trough, the stock will not knock it out.
  • Leave the drum dispensing in the trough for 48-72 hours.
  • When you return to collect the drum empty the water left in the drum into the trough (may be a weak tea colour.)
  • Repeat the process on a 3 weekly cycle.

For the best results, we recommend application via the water supply using the stainless steel Beachport Dispenser in the water trough. It simply screws into the top of a 5, 10 or 20-litre drum (BLM Empty Drums are available for purchase if required.)

Drums must NOT be completely filled (i.e. 20 ltrs in a 20 ltr drum). There has to be air pressure in the drum for the dispenser to work correctly over its 3-day dispensing period.

Why:  When you look at the dispenser it has an inlet and an outlet that are constantly under water in the trough so the air in the drum is trapped. For every ml of Beachport Liquid Minerals product that escapes through the outlet over the 3 days a ml of water is sucked back in through the inlet keeping the air pressure constant.  So if you put 15 litres of Beachport liquid supplement in a 20 ltr drum 3 days later Beachport liquid supplement product will be replaced by 15 litres of water due to the water pressure in the drum.

Note: Ensure at least half the drum contains product or a combination of Beachport Liquid Minerals supplement & water, to ensure flow rates are not affected.

IMPORTANT: Under no circumstances can Beachport Liquid Minerals products be mixed with other products in the water supply at the same time. This includes UREA.

  • Calculate the amount of product required based on the number of stock being supplied by the tank.
  • Pour the required amount directly into the tank. DO NOT turn off the tank, let it fill as normal.
  • Beachport Liquid Minerals livestock supplement should not be put in a tank with excessive sediment present.

Note: If multiple tanks in line ensure the closest tank to the stock is dosed.

  • Dose amounts remain the same (25mls per head for an adult dose).
  • You can pour the correct dose amount directly into the tank but ensure that the tank does not overflow. Ensure the header tank to be treated has NO leaks.
  • DO NOT turn tank water supply off risking stock running out of the water. Water flow is essential to allow the Yellow Cap supplement product to suspend in the water and clouds on the movement to the outlet.
  • Mix the required amount of product with approx 50% water that is sufficient enough to be able to evenly pour onto the hay that’s been fed out.
  • Add an extra 10% of product to allow for wastage.
  • Dose over at least 2 applications to ensure even distribution.

Key times of use

The Beachport Liquid Minerals Yellow Cap high magnesium product is to be used as a preventative, not a cure.

Be proactive at times that grass tetany and milk fever are traditionally prevalent.

Pre-calving/lambing: treat 6 weeks prior to lambing & calving

Please note: It is recommended that frequency is every 3 weeks and at half of the normal dose of other Beachport Liquid Minerals products. Refer dose rates for further instructions.


It is recommended to halve the normal dose for Beachport Yellow Cap (compared to other Beachport Liquid Minerals products) to increase the frequency to 3 weeks to ensure magnesium levels do not drop. Refer dose rates below.

EXAMPLE: 200 Breeders
200 breeders x 25 mls dose
Total 5,000 mls (5 litres)

A heifer you’re trying to get in calf, a cow in calf, or a cow with calf at foot to 200 kilograms is classed as a breeder unit.

DOSE RATES: Per Breeder unit
25mls per animal every 3 weeks.

IMPORTANT: Beachport Liquid Minerals products are NOT a daily application process. Dose amounts are for a 3 week period (one dose lasts 3 weeks.)

Calculated on animal’s weight.

DOSE RATES: Per head

201 – 300 kgs = 15mls
301 – 400 kgs = 20mls
401kg plus = 25mls

Essential ElementsTarget ResultUnit

This product also contains electrolytes (via fulvic acid) & amino acids (via kelp/seagrass extract).

Use Yellow Cap as a precaution before high risk seasonal conditions when there is a threat of grass tetany. Use every 3 weeks through this period until adequate pasture.

Beachport Liquid Minerals Yellow Cap high magnesium is a tool to use in your grass tetany prevention program. Using the Yellow Cap product may help prevent grass tetany, but it will not cure/treat grass tetany if the animal is already showing clinical signs.

Beachport Liquid Minerals is a feed conversion tool, this means that animals are able to utilise anything that is going down their throats more efficiently. For example: If you were to put urea in the water at the same time as Beachport you will find that the Urea will become 60% more available. This can be quite dangerous as urea can poison stock. If you use copper blocks for algae treatment, take them out prior to putting in the Beachport. Once the Beachport is out of the trough (4-5 days) you can put the blocks back in the trough. Once again the copper will become more available and may poison the stock.

You can use Beachport in conjunction with licks and block (containing urea) just not in the water at the same time.
