GrazFeed is a program developed by CSIRO that can be used to predict animal performance on pasture and or supplements and or estimate the amount of supplement or ration required to meet a required performance level.
Feed includes pasture and supplements
Useful training tool for understanding nutrition
Free android app with limited features and display
Detailed reports provided
Knowledge of pasture amount and quality
Reasonable computer skills
Work through the tables to estimate how much energy that sheep are getting from available pasture (dry pastures) , what they need (based on weight, condition score and reproductive status) to estimate how much supplement to feed.
All reference tables required are supplied
Supported by lifetimeewe training
Requires skill to assess amount and quality of dry pasture
For sheep only
Simple calculator of how much of two feed supplements to meet specific energy or protein requirements of an animal.
Simple to use for a 2 ration mix
Requires knowledge of animal requirements for energy and protein
Estimates for 2 feeds – one must be higher than requirements
An app that Determine the minimum feed requirement for a range of animals as well as formulate rations, compare supplement feed costs and costs on a per head or for the total period ‘as fed’.
Free app and very simple to use
All reference data built in
No allowance for pasture
One off result not stored
A step by step worksheet to estimate how much an animal needs to eat and the feed quality to meet their energy and protein requirements; compares feeds (cost /MJ), total cost of feeding period and how much the flock/mob require per day.
Step by step calculation for each measure of interest (e.g. feed cost comparison; minimum quality of supplement required)
Requires knowledge of an animal’s energy and protein requirements
Print and fill in – need a calculator
This calculator works out a simple gross margin to help make a decision on whether to finish/feed lambs or sell.
Simple calculator that provides drop down help boxes to fill in what you need
Requires input of costs, feed consumption and lamb weights (starting and selling) and market value
This calculator does a simple gross margin do help decide whether to feed a class of stock through a drought until a likely autumn break.
Simple calculator that includes total possible cost to feed and a probable cost, based on timing of autumn break
Requires input of costs, monthly expectation of feed per DSE (Dry Sheep Equivalent) and an estimate of a ‘realistic’ buy back price
A range of tools that estimates how long a paddock will last, or how many stock can be run. Includes a summer budgeting tool to estimate how long summer feed will last and a winter feed budget tool to estimate whether pasture targets for livestock will be met.
Range of feed budgeting tools (pasture based) and references such as image libraries and pasture growth
Reference tables provided
Requires good estimates of feed on offer (FOO)
Some tools require estimates of pasture growth rates, decay rates and how much stock will eat
It is used to calculate longer term quantities and costs to feed classes of stock over an estimated feeding period.
Simple cumulative spreadsheet estimating cost and total tonnage over likely drought/feeding period
Requires estimate of how much will be fed for how long
