CSIRO promotes elite saltbush to sheep and cattle producers

Sheep Central, July 24, 2023

CSIRO said Anameka Saltbush is an ideal supplementary feed for sheep in dry conditions.

SHEEP and cattle producers are being urged to consider planting an elite variety of Oldman Saltbush across Australia’s south-east this winter to supplement feed during dryer conditions heralded by a potential El Niño.

CSIRO’s Drought Resilience Mission is driving wider adoption of Anameka Saltbush in drought-prone regions across south-east Australia for the first time to build on the 325 farmers already growing the plant.

Anameka Saltbush is a specially selected variety of the drought-tolerant native shrub, developed over 15 years by CSIRO, Australia’s national science agency, with partners in government and industry.

It is unique for its higher nutritional value and improved palatability for livestock and its potential to regenerate the topsoil of land that is too saline or infertile.

CSIRO modelling indicates that Anameka shrub systems offer 20 percent higher economic returns compared to standard saltbushes, particularly in relatively dry years. This reduces exposure to financial risks associated with climate variability or drought.

Other benefits include greater wool and meat production and reduced supplementary feed, CSIRO said.

Southern New South Wales Merino sheep producer Marcus Hooke at Booroorban, is doubling the number of Anameka Saltbush in his paddocks after successful establishment last year.

“It’s early days but we believe the benefits of Saltbush will be long-term.

“For us the benefits will be two-sided in providing crucial shelter to lambs to improve their survivability out on the plains during colder months, and for feed to provide energy during dry seasons,” he said.

Anameka, as well as standard saltbushes, have traditionally been grown in Western Australia for salinity management. However, CSIRO said the new plantings build on six million Anameka Saltbush already planted across 8000 hectares, mostly in WA, since commercial release.

CSIRO’s Dr Hayley Norman selected Anameka Saltbush from 60,000 plants.

CSIRO agricultural scientist, Hayley Norman, said that during dry years when there is a shortage of available feed, Anameka Saltbush can provide key nutrients that improve livestock productivity and health.

“Anameka Saltbush is a moderate-energy, high crude protein and sulphur feed source that is full of essential minerals and antioxidants,” she said.

“It grows well on most landscapes, and once established, Anameka Saltbush can become a ‘living haystack’ for grazing livestock for more than 20 years if managed correctly.

“We’re now bringing these benefits to new regions across Australia’s southeast to carry farmers through poor seasons and build their resilience to drought,” DR Norman said.

CSIRO’s partners include Tulla Natives, Chatfield’s Tree Nursery, Select Carbon, Meat & Livestock Australia, WA government’s Department of Primary Industries and Regional Development, Australian Wool Innovation and several producer groups across Australia. The program has also received funding from the Australian government’s Future Drought Fund.

Anameka Saltbush is one of many farming system innovations that CSIRO’s Drought Resilience Mission is scaling to help Australia’s agricultural sector adapt and transform through future cycles of drought.

These include new decision-making tools, techniques to improve water use efficiency and facilitating the development of new financial tools to share risks.
