Build up mineral reserves to boost immune system

After all the monsoon type rainfall in recent months many farmers are experiencing depressed livestock performance.

A lot of soils have experienced leeching of many major elements and trace elements. Plus the wet grass and unfavourable grazing conditions have further hampered performance.

With the depleted mineral status it will be vital to top up trace element reserves coming into the winter month. Trace elements have many benefits and are the foundation of an animal’s nutritional status.


Selenium is important for good muscle development and the immune system. It also stimulates the production of prostaglandins.

Copper is important for skeletal development, thrive and appetite. It is counteracted by high Molybdenum. It is important in combating stress, prevents coagulation disorders and heart problems in calves and strengthens their bones.

Iodine is important for calf viability and fertility in cows.

Zinc is important for growth, immunity and fertility in both males and females.

Cobalt facilitates the synthesis of Vit B12 and energy metabolism. As a Cobalt supplement it provides Vit B12 to catalyse rumen fermentation and in particular the activity of methionine-synthesase.

Manganese is important for overall health and energy of the animal.

Magnesium supplementation initiates the metabolism of Mg that is essential for milk let down.


Osmonds stock a wide variety of mineral supplementation techniques including liquid doses, bags & buckets and tablets. Another cost effective and convenient way to administer minerals is through Boluses. Here is some information on Osmonds Bolus range



Osmonds Electromin High Fertility Bolus 
is a unique long acting bolus that provides a balanced supply of Manganese, Iron, Iodine, Cobalt, Selenium and Vit B12. High fertility levels have to be prepared during the drying-off and post-partum period and this bolus assists by providing essential elements to this phase.


Osmonds Electromin Copper Plus Bolus 
provides a balanced and controlled supply of Copper, Zinc, Iron and Selenium.



Osmonds Elite Dry Cow 
is a unique long acting bolus that provides a balanced and supply of Cobalt, Iodine, Zinc, Magnesium, Selenium and Vitamins for the dry cow period. It is formulated to provide 3 months cover i.e. the 2 months drying off period (before calving) plus 1 month post partum (after calving).


Osmonds Super Grazing Bolus 
is a highly concentrated bolus that provides a balanced and controlled supply of essential trace elements for the entire grazing season. It provides Zinc, Copper, Iodine, Selenium and Cobalt. It is formulated to provide cover the 9 months at grazing. It compensates the deficiencies in grass for trace elements to support each physiological stage (lactation, reproduction, pregnancy and calving).
