  • Tall fescue endophytes
    Patent number: 6111170
    Abstract: Selected endophytes of the genus Neotyphodium (formerly Acremonium) form stable synthetic combinations with tall fescue hosts (Festuca arundinacea). The combinations have improved resistance to invertebrate pests as compared to tall fescue cultivars not containing such endophytes. The particular combinations of the invention have reduced toxicity to livestock as compared to naturally occurring endophyte/tall fescue combinations. The seven preferred endophytes are AR501, AR502, AR510, AR542, AR572, AR577 and AR584.

  • Ryegrass endophytes
    Patent number: 6072107
    Abstract: Selected endophytes of the genus Neotyphodium (formerly Acremonium) form stable synthetic combinations with ryegrass hosts (preferably Lolium perenne). The combinations have improved resistance to invertebrate pests and drought effects as compared to ryegrass cultivars not containing such endophytes. The particular combinations of the invention have reduced toxicity to livestock as compared to naturally occurring endophyte/ryegrass combinations. The six preferred endophytes are AR1, AR12, AR22, AR50, AR52 and AR56.

  • Device for administration of beneficial materials to ruminants
    Patent number: 5720972
    Abstract: The invention described is a bolus for the controlled release of a beneficial agent in the rumen of a ruminant animal. The bolus consists in a core containing a binder, solubilising agent, the beneficial agent to be released and, when required, a densifier. The core is coated with a wax coating, preferably with an opening exposing a small part of the core to rumen juices. The core is gradually dissolved releasing the beneficial agent. As the core dissolves the wax coating erodes until the bolus disappears completely.
