As Australian sheep producers navigate a landscape of fluctuating commodity prices and challenging seasonal forecasts, the imperative to maximise reproductive efficiency and build flock resilience has never been more critical. In response to this need, we are thrilled to announced the launch of the new Multimin® Evolution for Sheep1 range, an advanced trace mineral injection now formulated with 50% more zinc to directly support fertility, immunity, and productivity.
The launch comes at a time when many producers are focused on strategic flock growth, either rebuilding numbers after recent dry spells or capitalising on strong market sentiment for quality lamb and wool. However, high input costs and an unpredictable climate mean that every breeding animal must perform at its peak. Optimising scanning rates, increasing marking percentages, ensuring lamb survival and weaning weights are the cornerstones of profitability in the current environment.
The enhanced formulation of Multimin Evolution for Sheep directly addresses these challenges. Zinc is the second most abundant trace mineral in the sheep's body and is essential for over 300 metabolic functions, including those critical for reproduction and immune response.

"We know Australian producers are focused on efficiency and maximising the genetic potential of their flock. Every dry ewe and every lamb lost impacts the bottom line," said Dr. Paula Gonzalez-Rivas, Senior Technical Services Manager for Livestock at Virbac Australia. "We specifically enhanced the zinc concentration in Multimin Evolution for Sheep to target those key drivers of productivity – fertility and immunity. It’s about providing a tool that delivers tangible results when it matters most, particularly in the lead-up to joining and during pregnancy."
The role of trace minerals in optimising sheep fertility is well-documented. For ewes, the strategic administration of Multimin one month before joining has been shown to improve fertility by improving embryo survival leading to an average increase in conception and marking rates of 9%2,3. The antioxidant enzymes synthesised from zinc are vital for ovulation and the survival of the early embryo.
For rams, the benefits are equally significant. Zinc is a fundamental component of sperm production. Using Multimin Evolution for Sheep three months prior to joining, and again at joining, supports ram libido and improves key sperm parameters, including quality, concentration, motility, and morphology. The result is more lambs on the ground and a tighter lambing pattern.

Beyond its primary role in reproduction, the enhanced zinc levels also contribute to robust immunity and flock health. "Sub-optimal zinc levels can open the door to a range of costly health issues, from hoof infections and respiratory diseases," Dr. Gonzalez-Rivas added. "By supporting the integrity of the skin, hooves, and mucous membranes, Multimin Evolution for Sheep helps build a stronger first line of defence, allowing the flock to better cope with environmental and disease pressures."
The new Multimin Evolution for Sheep is rapidly absorbed and provides sustained activity during high demand periods, ensuring your flock has the critical trace mineral support needed to thrive.
