Feeding Leucaena for maximum beef profit – Webinar

Join Department of Agriculture and Fisheries (DAF) researchers in this webinar as they share new management adoption strategies for Leucauena. 

Learn about:

1. Mapping potential land areas suitable for expansion of Leucaena pasture systems across northern Australia and how expert knowledge and existing spatial data sets can be used to map potential Leucaena distribution in Queensland, the Northern Territory, and northern Western Australia, estimating that up to 27.3M hectares of land in Northern Australia could viably support Leucaena (including 4.6M hectares in humid coastal areas of Queensland that are suitable for the psyllid-resistant Redlands cultivar).

2. Release of the psyllid tolerant Redlands cultivar in 2019 has invigorated leucaena adoption in northern Australia where uptake was previously limited. Grazing performance was measured in a multi-year trial at Pinnarendi near Mt Garnet. Several North Queensland based producers are continuing to establish significant areas of Leucaena across a range of soil types and are adapting planting and management techniques based on their initial experience with good results.

3. To achieve maximum benefits when grazing Leucaena cattle need rumen bacteria capable of degrading the toxins mimosine, 3,4 DHP and 2,3 DHP. Our research found that the Redlands cultivar had a negative effect on the DAF Leucaena inoculum leading to the development of a new mixed bacterial inoculum (TriMix), adapted for better utilisation and detoxification of different Leucaena cultivars including Redlands, Wondergraze and Cunningham. They also investigated if Queensland cattle possess rumen bacteria capable of degrading the toxins mimosine, 3,4 DHP and 2,3 DHP or would benefit from receiving the TriMix inoculum when being introduced to Leucaena-pasture grazing.
