A quick and simple way to calculate a number of common grazing related equations used by dairy and beef farmers. This app is the brainchild of a dairy farmer, who wanted a fast and easy way for him and his workers to be able to do grazing related calculations, and was designed and developed in collaboration with his sister, with input from other farmers and farm advisors. Designed to be used out on the farm and on the go, this app makes it quick, easy and simple for anyone working on a dairy or beef farm - regardless of their level of experience and knowledge - to get the numbers they need, when they need them. About the calculators (visit our website for more detailed descriptions): ● Days in Paddock - Work out the approximate number of days to leave a specific number of cows in a paddock using either: ◦ kgDM/cow or lbDM/cow allocation, paddock size, cover and residual. ◦ m2/cow/day or yd2/cow/day allocation and paddock size - These results can then be used to calculate approximately where to put the break fence in a paddock. ● DM/Cow/Day - Work out approximately how many kgDM/cow/day or lbDM/cow/day you will get from a paddock based on paddock size, cover, residual, number of cows and number of days. - This result can then be used to calculate approximately where to put the break fence in a paddock ● Crop Allocation - Work out the approximate area of crop to allocate and the approximate number of days you can leave the cows in a paddock based on yield, the number of cows, the kgDM/cow/day or lbDM/cow/day required and paddock area. - This result can then be used to calculate approximately where to put the break fence in a paddock ● Pre-Grazing Cover - Work out the approximate target pre-grazing cover or the paddock trigger level based on stocking rate, intake, round length or rotation and the optimum residual. ● Average Pasture Cover - Work out the approximate average pasture cover for your farm based the pre-grazing cover and optimum residual. Enter the values directly or use the result from the Pre-Grazing Cover calculator. Other Features: ● Choose to do the calculations in Metric or US system of measurement. On first installing the app will be promoted to choose from using either the Metric or US system of measurement. You can change the selected units at any time via the Settings. ● Share the result of the calculation using any of the available options off your device. ● Settings options for the shared content: - send answer only, or send the answer and variables - include or don't include units - always edit before sending, never edit or choose each time whether edit or not ● Add a note after completing the calculation e.g. paddock or mob name. This note will be included in the shared content. ———————————————————————— Thanks to everyone who has given feedback and suggestions!

But it does not give you the option to choose whether you are feeding a dry beef cow or a milk producing cow requiring more feed. Its a very general approach to pasture allocation, that is all. ### 5/5 — VG App *2014-06-06, version 1.3.4* Awesome App!! Makes life an absolute breeze. Especially love the crop allocation one. Once you put in primary fence length it does it all for you! Highly recommend to all farmers ### 2/5 — Glitches! *2014-05-28, version 1.3.4* When I downloaded this the first time it was unresponsive, I'm a little apprehensive to download a second time...hopefully you've mended ALL the glitches, would be a great app for the farm otherwise!!! ### 5/5 — Great app for farmers *2013-11-01, version 1.1.0* Awesome app, no need for pen and paper you can do it all straight away ### 4/5 — Solid app *2013-10-14, version 1.1.0* This calculator is a great tool for anyone in charge of a herd. Takes all the guess work out of feeding equations. However, the SMS feature is a little hard to read & could potentially confuse others. Could do with clearer headings. Other than that it's perfect. ## Frequently asked questions about Grazing Calculator ### What types of calculations does Grazing Calculator perform?
