OHAU is the latest generation of tetraploid long rotation ryegrass. It has 75% perennial and 25% Italian ryegrass genetics. OHAU has a mid to late heading date and was bred for high-production and quality.
OHAU is a long-rotation ryegrass that has strong winter and early-spring activity. This allows OHAU to contribute valuable growth in the critical early-lambing and calving periods. OHAU is an extremely palatable grass with a high feed value. OHAU’s palatability results in pastures with a high green leaf content over summer.
OHAU is the ideal option for high quality, medium to long-term pastures, in conditions suited to tetraploid ryegrasses. OHAU is also available with the new AR37 endophyte, which offers improved resistance to insects (e.g. Black Beetle, Root Aphid, Pasture Mealy Bug).
Animal Health:Although AR37 does not produce Lolitrem B it can cause ryegrass staggers. Trials have shown that on average the frequency, duration and severity of ryegrass staggers is less than for standard endophyte. However on occasions, sheep (and potentially other animals) grazing AR37 ryegrass may be severely affected. After many years of use, ryegrass staggers have not been observed in dairy cows on-farm to date. AR37 varieties should not be used on properties grazing either deer or horses.
