Coorong CM142 ryegrass: Proven performance in Denison, Vic
August 28, 2025 Australia
A persistent and productive ryegrass for dairy systems
For Brad Vanderland, finding the right perennial ryegrass meant striking a balance between persistence, productivity, and milk production—without compromising the litres going into the vat. Farming in Denison, Victoria, part of the Macalister Irrigation District, Brad needed a ryegrass variety that could withstand variable conditions while delivering high-quality forage for his dairy herd.
Looking for something different, Brad reached out to the AlfaGen Seeds team for expert advice. The solution? Coorong CM142 ryegrass—a tetraploid perennial ryegrass bred for strong tiller density, cool-season growth, and long-term pasture persistence.
Establishment success in two sowing systems
Brad trialed Coorong CM142 tetraploid perennial ryegrass across two different paddock establishment methods:
- Direct drilled into existing pasture
- Fully cultivated paddock before sowing
Both paddocks established well, but what really stood out was the tiller density.
“The tiller density is what has impressed me the most.” – Brad Vanderland
As well as breeding for high pasture yields and quality, tiller density was also a key focus in the selection process for Coorong CM142. Higher tiller density enhances robustness and persistence, making the pasture more resilient under grazing pressure. This is especially true when combined with CM142 endophyte, which provides added insect tolerance without compromising animal safety.
Extending high-quality feed later into the season
Dairy production relies on consistently high-quality pasture throughout the season. As a late-maturing perennial ryegrass, Coorong CM142 maintains strong feed quality well into spring. Brad’s results showed a clear benefit:
“Throughout the later spring months, the herd have lifted or held quality and litres in the vat when they are grazing on the Coorong CM142 ryegrass.”
This showcases Coorong CM142’s later heading date, providing an extended window of high-energy grazing, critical for supporting milk production and maintaining cow condition.
Why choose Coorong CM142 ryegrass?
Coorong CM142 was developed specifically for high-performance Australian farming enterprises, with a strong focus on yield and quality, supported by tiller density, seasonal growth, and persistence.
It offers:
- High tiller density for improved pasture persistence and resilience
- Cool-season growth for extended forage production
- Late heading date to maintain feed quality deeper into spring
- CM142 endophyte protection for increased insect tolerance and pasture longevity
For farmers like Brad, Coorong CM142 is proving to be a game-changer for persistent, high-performance pastures.
