Eragrostis curvula – Weeping Love Grass
Eragrostis is probably one of the hays I know best. It is the hay I grew up with — we produce it on the farm and feed it to our own horses through winter. So, this is one forage I have plenty of practical experience with, as well as experience looking at its nutritional value through forage analysis.
Eragrostis curvula, commonly known as Weeping Love Grass or Oulandsgras, is a perennial, tufted grass and an important hay grass in South Africa. It can provide grazing when managed correctly, but it is generally better suited to hay production. If it is grazed, it needs to be carefully managed and should not be grazed too short.
Eragrostis responds well to appropriate fertilisation, which can significantly increase production. Under good growing conditions, it can be cut 2–3 times a year.
Production and nutritional value will, however, depend on rainfall, soil fertility, fertilisation, growing conditions and, importantly, the stage at which it is harvested.
Eragrostis is a more fibrous forage than Teff, with more lignin and less digestible fibre. As the plant matures, fibre increases while protein, energy and digestibility decrease. This means that the maturity of the hay at harvest can make a significant difference to its nutritional value.
From my analyses, I find Eragrostis generally provides around 4–7% crude protein, although individual batches can vary. Very young, well-fertilised hays can reach 12–14% protein, although these are very rare.
Eragrostis provides around 1.8 Mcal/kg of energy. Calcium generally falls around 0.15–0.24%, while phosphorus is around 0.12–0.17%.
Mineral levels can vary depending on the soil, fertilisation and growing conditions. In my experience, Eragrostis generally provides more minerals than some veld and Red Grass hays, but tends to be lower in mineral content than Teff.
SO WHO IS ERAGROSTIS GOOD FOR?
This is where I really like Eragrostis - Because it is a more fibrous forage with a lower energy density, it can be a very useful forage for easy keepers and horses needing to lose weight. For horses with higher energy or protein requirements, however, Eragrostis may not provide enough on its own — particularly when the hay is mature.
And this is where my own experience with Eragrostis becomes important. I have found that horses eating Eragrostis often need additional protein and essential amino acids, followed by careful balancing of the rest of the minerals.
But - and this is important - not every horse eating Eragrostis needs exactly the same supplementation. The quality, maturity and amount of hay the horse eats will determine what the rest of the diet needs to provide.
WHAT ABOUT GRAZING?
Although Eragrostis can be grazed, it needs careful management. It is a tufted grass and can be damaged by overgrazing or grazing too short for prolonged periods. Good grazing management is important to maintain the stand and allow the grass to recover.
THE BOTTOM LINE
Eragrostis can be an excellent forage when matched to the right horse and fed with the right feeds and appropriate supplementation.
Its higher fibre content and lower energy density can make it particularly useful for easy keepers and horses in lighter work. Horses with higher nutritional requirements may, however, need additional energy, protein, amino acids and minerals to balance what the hay provides.
As always, don't just ask:
“What hay is my horse eating?”
Ask:
“What is this particular batch of hay actually providing?”
Know your forage. Know what it provides. Then feed the horse in front of you.
