There are twenty-one minerals considered to be nutritionally important. They can be grouped into major minerals and trace (minor) elements. Of the major minerals calcium, phosphorus, sodium, chlorine, potassium, sulphur and magnesium are considered important. Important trace elements are copper, cobalt, iron, iodine, zinc, manganese and selenium.

Mineral deficiencies, and in some cases imbalances, can cause metabolic disturbances and can produce specific deficiency diseases. Fertility, and hence calving percentage, can be affected. Milk production is obviously dependent on the health and the well-being of the dairy cow and any metabolic disturbance will affect milk production.

Mineral and dietary supplements within the AHD Limited product range include Stock Iodine, Calf Oral Electrolytes, Reload Copper capsules, Vitamec D3, Vitamec AD & E and Selenium.

If you have specific questions relating to mineral and dietary supplements please contact your Farm Consultant or Veterinarian for specific recommendations for treatment and prevention.


Guaranteed instant calcium release

Reduces the risk of Milk Fever by increasing the levels of calcium in the blood to a level that the cow will not suffer metabolic problems.

Also contains Vitamin D3, Phosphorous and Magnesium

Calcium deficiency after calving can lead to milk fever, especially from the second calving and later calving cows that are more sensitive.


Heading towards calving, cows are facing the most stressful period of the year

Key factors are the traditional feed management methods typically low in dry matter intake, hormone secretion, bone rebuilding and the most impact on them, metabolic changes.

Over the drying off period and leading into calving the cow needs to rebuild every aspect of her body to prepare for the new lactation season and to help combat metabolic disorders.

Science tells us that in each lactation a cow can lose around 500gm of calcium from her natural storage, bones, and even teeth being the sources. This draw-off of calcium and phosphorus is going into her milk.

Biggest impact is on the higher producing and older cows which succumb to milk fever.

It’s a tough period under the New Zealand grazing and winter conditions.

This is the time to ensure the cow is administered the likes of Drytop 10-week slow release bolus to ensure she is getting the mineral intake and build up on a daily basis to help get her into shape prior to calving.

Just on calving or just post calving, Calcitop will supply her with the important source of Calcium, Phosphorus and magnesium.

Bolus applications offers precise and accurate mineral uptake, no mess, you know she has it and the risk of metabolic disorder is greatly reduced.
