Shaping the future of animal health

Injectable trace minerals essential for post-weaning

Young growing stock are under increased levels of stress, even more so after they are weaned. The weaner is undergoing a change in diet and suffering separation stress from its mother. As a result feed intake can drop, reducing mineral intake from pasture and other sources.

Trace minerals play a vital role in feed digestion and the development of bones, muscle and teeth; and deficiency could result in decreased appetite and feed conversion, lower daily gains and a decreased immune system.

To understand what minerals young stock require, it is important to know what they are receiving in the first place.

While very high levels of minerals are delivered to calves through colostrum, but by the time the calf is marked, immunity obtained from the colostrum begins to diminish along with trace mineral and vitamin reserves; therefore, a “top-up” injection of trace minerals is vital for growth and immunocompentence (immunity).


Trace minerals play a vital role in growth - promoting feed digestion and the development of bones, muscle and teeth. Deficiency can result in decreased appetite and feed conversion, lower daily gains and a decreased immune system.

To maintain optimal weight gain of 0.7 kilograms per day, the nutritional status of the animal including trace elements must be adequate.

Immune function

Young cattle have an underdeveloped immune system and are more susceptible to parasite challenge and disease. Minerals have strong links with immune function and overall health of animals.

This is particularly important during the transition from weaning to pasture as it is the immune system that is challenged and often compromised during this stressful event.

Why an injection?

The use of a strategic injection is important because it is difficult to optimize the trace mineral functions of weaners when oral supplementation strategies are used. Relying on oral forms of supplementation allows for variation between animals in intake.

Minerals received through oral supplementation are also often antagonized (rendered unavailable for absorption from the gut) by calcium, sulfur, phosphorous, molybdenum and fibre resulting in sub-optimal to defi cient levels of essential elements during the critical growth period of young stock when they are needed most.

An effective way to counter dietary antagonists, increase bioavailability and ensure that weaners receive adequate amounts of essential minerals is to provide trace minerals post-absorption (i.e. bypassing the gastrointestinal tract with an injection directly into the animal for uptake through the blood).

MULTIMIN is a new concept of trace mineral supplementation for Australian cattle producers. This multi-mineral injection is designed to be administered strategically to “top-up” essential trace minerals – selenium, copper, zinc and manganese – at the critical time of pre- and post-weaning.

MULTIMIN uses patented technology that presents the four most important trace minerals for immune function, reproduction, growth and production – selenium, copper, zinc and manganese – in a highly bioavailable form.

MULTIMIN injection for cattle is formulated to be tissue friendly, aqueous and easy to use. It has nil meat and milk withholding periods and does not leave any colour staining of the subcutaneous tissue resulting in the need for extra trimming.
