Mix components

Formulation 2023

Component
Prairie Grass
Prairie grass or Pasture Brome grass (Bromus sp.) is a grass that is tolerant to drier conditions due to deep root system. Its sugar and starch concentrations average around 10 to 15% in comparison to ryegrass at 30%+ and is highly palatable to the horse. Protein levels, as high as 12% are achieved at certain stages of its growth. This species of prairie/brome grass is specifically bred as a pasture grass and has no adverse effects on livestock, including horses.
Serradella
Serradella is a winter dominant, deep rooted annual legume which grows mainly during the Autumn, Winter, and Spring months. Being a legume, it has good levels of protein, consistently low in sugars and starch, highly palatable to the horse, and provides nitrogen fixation to improve the soil quality.
Tall Fescue
Tall Fescue is another common horse pasture with reasonable (around 15%) sugar and starch levels, highly palatable for horses and provides an excellent swarth of feed when required. Growing reasonably well in drier conditions, its deep root system does give it some resistance to the dry. Its main growing period is late spring/early summer.
Teff grass is naturally low in sugars through most of the growing season plus fair protein levels (around 9%). During the plant’s young, growing stage, it is very palatable feed. As it matures though and starts to dry off, both its palatability and nutrient value start to fall. While it is a very good horse feed it does, like most C4 tropical grasses, contain an amount of oxalate (the calcium binding compound). While the oxalate concentration isn’t large, it is still present and therefore it is important that the Teff grass is not the only pasture species in the grazing paddock.
Finecut Rhodes grass is very resilient to drought and heavy traffic. Rhodes does most of its growing during later Spring/Summer before drying off. Rhodes grass retains very low concentrations of sugars in the leaves at most stages of growth. Coupled with good palatability and very low concentrations of oxalates, this makes Rhodes the ideal horse safe pasture species.
Callide Rhodes Grass being a tetraploid, Callide Rhodes grass is more palatable and tends to be preferentially grazed when sown with other sub-tropical grasses. Callide Rhodes grass has a high number of growing points with a more prostate growth habit than more recent releases and is coarser in the leaf and stem. It is also summer active where soil moisture is available.
Cocksfoot
Cocksfoot is a perennial tufted grass that is best grazed before flowering, and no lower than 5cm to allow for regrowth. Cocksfoot is hardy, drought resistant with deep roots. Endophyte free, tolerant to pest attack but can suffer from rust until established. Yarck Cocksfoot is a summer activity variety.
Lucerne
Lucerne provides a beneficial perennial legume component to this mix. Lucerne is a very nutritious feed and source of fibre. It contains about 18% high-quality protein which provides good levels of all the essential amino acids for horses, including lysine, which can be low in many feeds, including grains. It is high in digestible fibre, including pectin, which provides sustained energy (it is converted to glucose, glycogen, and fat in horses’ livers) and is very good for digestive health because it promotes beneficial gut microflora. Lucerne is readily available, very palatable, and highly digestible.

*Occasionally some varieties in our mix will be replaced with a like-for-like variety where the original is not available or not easily accessible. Varieties in the mix will be specified on the bag label.

About this variety

Equi1st is an Irwin Hunter blend formulated specifically for horses, and it exists because horses are not cattle and should not be grazed as though they were.

Horses are not physiologically designed to cope with the high sugar and protein levels that traditional pasture mixes deliver. An ideal horse pasture is relatively low in sugars and starch and moderate in protein, while remaining palatable enough that the animal will eat it. That is a harder specification than it sounds, and it is why a general purpose pasture mix is a poor choice for a horse paddock.

Equi1st combines teff, prairie grass, serradella, tall fescue, Rhodes grasses, cocksfoot and lucerne, species selected for that sugar and protein profile rather than for maximum production. The blend is also tolerant of animal traffic and grazing, which matters on horse paddocks that carry concentrated use.

It improves the soil as it establishes, and it is suitable for all other livestock as well.

Because several components are tropical grasses that contain oxalate, the mix is designed so that no single species dominates the paddock.

Planting & grazing notes

Optimal sowing time Autumn/Early Spring; sow when soil temperatures are 16°C+ and rising as some species are tropical (C4); introduce horses to lush pasture gradually; mow unpalatable clumps not grazed since horses are preferential grazers. Equi1st has been specifically designed to benefit your horses, improve your soils and is tolerant of animal traffic and grazing. While the oxalate concentration isn’t large, it is still present and therefore it is important that the Teff grass is not the only pasture species in the grazing paddock. Cocksfoot is a perennial tufted grass that is best grazed before flowering, and no lower than 5cm to allow for regrowth.

Disease & pest resistance

Growing reasonably well in drier conditions, its deep root system does give it some resistance to the dry. Endophyte free, tolerant to pest attack but can suffer from rust until established.

Stand life

Do not graze for 4-6 months after planting (up to 8 months on very sandy soils) to allow root structure to establish; refrain from cutting for hay in the first year to encourage persistence. Reduce competition – Ideally spray out any existing pasture / persistent weeds before planting. This helps to maximise continued productivity and persistence.

FAQs

What pasture seed is safe for horses that are prone to laminitis?

We recommend our Equi1st Pasture Mix, developed specifically for horses to be low in sugar and starch with moderate protein. It blends selected legumes and annual and perennial grasses. It suits sandy to heavy soils with pH 5.0+ and 400mm+ rainfall. Always check with your vet for horses at high risk.

What should I sow on my horse agistment block in the Perth Hills?

Our Equi1st Pasture Mix is designed for horses and suits 400mm+ rainfall on sandy to heavy soils with pH 5.0+. It includes grasses such as Teff, Rhodes grasses, Tall Fescue, Prairie Grass and Cocksfoot plus serradella and lucerne, and tolerates animal traffic and grazing.

When should I sow a horse pasture with summer grasses in it?

We recommend sowing our Equi1st Pasture Mix in autumn or early spring when soil temperatures are 16°C and rising, because some species are tropical C4 grasses. Sow as shallow as possible for good seed-to-soil contact. Tropical species germinate poorly in cold soil, so sowing too early can leave gaps in the stand. It suits 400mm+ rainfall.

How long should I keep horses off a newly sown paddock?

For our Equi1st Pasture Mix, we recommend not grazing for 4 to 6 months after planting, or up to 8 months on very sandy soils, so roots establish. Avoid cutting for hay in the first year to encourage persistence. Then introduce horses gradually.

What grass stays green all year for horses in WA?

Our Equi1st Pasture Mix combines winter and summer active species for year-round production, depending on soil moisture. Tropical grasses like Rhodes grass and Teff grow in summer, while Prairie Grass, Tall Fescue and Cocksfoot grow in cooler months. Lucerne and serradella add legume protein. It suits sandy to heavy soils with pH 5.0+ and 400mm+ rainfall.

My horses won't eat some clumps in the paddock. What should I do?

Horses are preferential grazers, so they leave some patches. With our Equi1st Pasture Mix we recommend mowing unpalatable clumps so the pasture regrows evenly. Rotational grazing also helps spread grazing pressure, and resting paddocks lets preferred species recover. The mix is designed to tolerate animal traffic and grazing, which helps on busy horse blocks.

Is it OK to feed horses only tropical grass pasture?

We don't recommend a single tropical grass species, because Teff and many other C4 grasses contain oxalates that can affect horses' calcium balance. Our Equi1st Pasture Mix combines several grasses and legumes so no single species dominates. Talk to your vet about mineral supplements.

How much Equi1st Pasture Mix do I sow per hectare?

We recommend 25 to 35 kg/ha for Equi1st Pasture Mix, sown as shallow as possible. It suits sandy to heavy soils with pH 5.0+ and 400mm+ rainfall. Sow when soil temperatures are 16°C and rising, in autumn or early spring. Keep horses off for 4 to 6 months after sowing.

Can I cut hay from Equi1st Pasture Mix?

Yes, Equi1st Pasture Mix can be used for horse-safe pasture and hay. We recommend avoiding hay cutting in the first year to help establishment and persistence. After that, it can produce quality grass hay for horses. The mix is designed to be low in sugar and starch with moderate protein, which suits many horse feeding programs.

Is Equi1st Pasture Mix only for horses?

No, Equi1st Pasture Mix was developed for horses but is suitable for all livestock. It is a perennial option that provides year-round production depending on soil moisture. Its blend of grasses and legumes suits mixed grazing by cattle and sheep too. It needs 400mm+ rainfall and pH 5.0+.
