Mixed forage systems incorporating native perennials could provide the answer to more sustainable and profitable livestock production and land management. With the right management, livestock perform well on diverse plant mixtures offering a wide range of plants in their diet. Research indicates that shrubs can contribute up to third of the dry matter intake of sheep.
AWI supported the Enrich program to explore the role of Australian native shrubs in grazing systems in the low-medium rainfall sheep/wheat zone. Enrich modelling showed that a 'typical' farm in the target zone could increase whole-farm profit by 15 20 per cent by including 10-20 per cent perennial forage shrubs to:
Merino sheep eating a forage shrub.
The Enrich team identified over 100 shrubs, trees and creepers native to the sheep/wheat or semi-arid zones that are palatable and have:

Nutritive Value of Rangeland Plants - AWI funded a review of the nutritive value of rangeland plants. The report compares feed quality data with actual animal performance from pastoral zone feeds, and documents pastoral woolgrowers' use of cost-effective, environmentally sustainable supplementation strategies.
