GrazFeed

GrazFeed is a Decision Support Tool developed by CSIRO Plant Industry that provides a simple way of applying feeding standards to grazing animals. The main object of the program is to help farmers and graziers to make the best use of their pastures, to minimize the use of expensive supplements and to select the most efficient supplement where feeding is necessary.

Drought feeding

The program estimates the animal production obtainable from the pasture and shows the extent to which production might be improved through supplementation.

GrazFeed is suitable for any type of pasture but is not designed for rangelands where shrubs and isolated plants make up much of the vegetation. The program is suitable for any breed of sheep or cattle; a generality that is achieved by scaling the biological functions in the program to the mature weight of the particular animal and breed type that is selected. These functions conform to the recommendations in ‘Feeding Standards for Australian Livestock. Ruminants’ (1990), prepared for the Standing Committee on Agriculture, with up-to-date modifications.
