AusWest MAXImiser® Eastern Horse Mix
The MAXImiser® Eastern Horse Mix is perfectly suited to the equine industry due to the grass species in this blend having exceptional tolerance to hard grazing. The combination of prairie grass, a grazing brome and an early flowering perennial ryegrass offer a strong grass based pasture with quality feed spread through autumn, winter, spring and early summer. Lucerne and clovers are also included in this blend to increase the overall quality of this mixture.
Queensland Summer Horse Mix
This unique blend of tropical and temperate species combines high quality feed with persistence. The tropical grasses provide summer bulk and have been carefully selected for quality, while the temperate grasses provide quality winter feed. The addition of temperate and tropical legumes allows for year round quality and nitrogen production. This mix is ideal where long term persistence is
required.

AusWest MAXImiser® 'New England Cocksfoot’
The MAXImiser® New England Cocksfoot mix is ideal for granite and lighter trap soil as well shallow, Stoney and/or slightly acidic areas. Savvy Cocksfoot is a soft leaved, highly summer active cocksfoot that is equally well suited to low input extensive systems as well as performing extremely well under a more intensive fertiliser and management program.
AusWest MAXImiser® 'New England Fescue
Our Maximiser® New England Fescue mix is custom built for high performing basalt and heavier trap soils. Tall fescue is the “King Of Spring” bringing forward your spring flush. The deep root system of Tall fescue allows it to access moisture at depth, otherwise unavailable to shallower rooted pasture plants. Hummer Max P tall fescue
is routinely among the top performing varieties at Toombs. It is a soft leaf variety giving it excellent stock acceptance and increased livestock performance.
AusWest MAXImiser ® Equine Italian Stallion Mix
Your horse needs good quality feed to maintain condition through winter. Combining Annual & Italian Ryegrass with Atom Prairie grass will provide high quality feed through winter spring and well into summer in higher rainfall zones.

Choice
Choice is a perennial chicory herb demonstrating 3-4 year persistence and a high level of summer dry matter production. This inexpensive herb provides high forage quality and warm-season pasture growth, with a deep taproot resulting in a consistent growth rate, even during dry spells.
Choice chicory can be added to new grass pasture mixes to boost animal performance and feed production.

Ecotain®
Ecotain® environmental plantain is a mineral rich perennial grazing herb. Ecotain® is fast establishing and tolerant to a wide range of soils. This includes less fertile soils and especially dryland regions of approximately 600 mm rainfall. Ecotain® has a deep coarse root system, which gives it a degree
of drought tolerance and the ability to respond quickly after summer dry conditions. Ecotain® pastures offer some great animal performance potential for sheep, beef and dairy farmers, particularly in winter and spring, as well as supporting a high level of animal health, reduced incidence of dags in sheep and good micronutrient supply (Zn, Cu, Se, MG, Ca, K). Pure stands of Ecotain® can be used during lambing to increase lamb and ewe weights at weaning. It can also be used for lamb or beef finishing systems and in dairy enterprises. Ecotain® has been shown to reduce nitrate leaching by up to 89% in lysimeter studies, benefiting your farm and the environment*. Ecotain® can be sown alone as a pure stand or recommended in perennial pasture mixes, especially medium term, quality finishing mixes.
