Improve the Sustainability of Livestock Farming
Traditional grazing of livestock can very easily suffer in times of drought or feed shortage.
Establishing and properly managing forage plants can be a practical and sustainable solution.
What Forage Plants can do for a farm:
- Diversify food sources for animals
- Improve land sustainability and health through a more biodiverse ecosystem
- Reduce the cost of feeding livestock
- Improve the variety of foods available to animals - potentially improving animal health
- Buffer the land degradation effects of erosion, flood, drought and natural disasters
If you select appropriate, disaster resistant but edible plant species; then establish them in appropriate places, livestock and farm viability can benefit immensely.

Aims
-
Discuss the nature and scope of forage plants eaten by animals, both in captivity and in the wild.
-
Identify the comparative characteristics of grasses and other low growing fodder plants from different natural and created habitats, including grasses, legumes and forbs.
-
Identify the comparative characteristics of grasses and other low growing fodder plants from different natural and created habitats including a range of trees and shrubs.
-
Explain how forage plants may be established effectively in a managed pasture.
-
Explain how to manage a landscape to optimise forage production in a way that is sustainable, both economically and environmentally.
-
Explore factors that impact the quantity and quality of forage produced by a landscape and the effect on productivity of forage production.
-
Identify common problems that can arise in livestock and other animals as a result or the forage/fodder they eat.
-
Harvest and store forage plants for feeding animals after a period of storage.
What is Fodder?
Fodder is plant material that is eaten by animals; usually grazing animals including horses, cattle, goats, deep, sheep and/or pigs.
Fodder can come from a wide variety of different plants, though most commonly it is from mostly grasses, with other low growing plants including legumes, growing among the grasses. These are generally low, herbaceous plants. Fodder plants can however also include woody plants such as low growing heaths, through to shrubs and trees. Fodder ecosystems might or might not be managed, to a larger or lesser degree.
The terminology can be confusing as much of it intertwines and varies depending on your location. In some countries pasture refers to landscape that are intensively managed to feed livestock; and relatively unmanaged landscapes which are used to graze livestock is called rangeland. In other countries the term pasture may be used in reference to both managed and unmanaged landscapes which are used to feed animals.
Different plant species vary in the food value for animals, and different animal species vary in their ability to process different types of plants. Cattle that are grazing on grassland do like to eat different types of herbs as well as the grass. This helps to fulfil nutrient requirements which the grass alone cannot satisfy. A varied diet can build resistance to disease and parasites, and also affect the quality of milk and meat produced; sometimes in a positive way, and sometimes in a negative way, e.g. the weed Paterson’s Curse, taints the flavour of cow’s milk.
There are 3 ways of using land for fodder:
- Animals graze on living plants in the pasture or rangeland
- Animals are fed harvested plant material cut from fodder plants
- Animals can graze on stubble left in a paddock, after fodder plants have been cut/harvested.
