What does Rumen8 do?
Rumen8 allows the user to design a diet from up to 15 feeds or mixes and ensure a cow’s dietary needs are met. Multiple diets can be stored and compared and if milk and feed prices are entered, the difference between feed price and return from milk calculated.
Rumen8 uses a relatively simple nutrition model that we have found accurate enough over many years using it on farms and Research Stations. More sophisticated models of dairy cow nutrition exist but they require a higher level of user knowledge, depend on less readily available and more expensive feed analyses, and require more time to use. We have found that Rumen8 provides a good balance between ease and speed of use and performance that is fitting for the pasture-dominated dairy diets common in Australia.
Dairy Australia independently evaluated Rumen8 version 1 (many years before they owned it) against a range of nutrition models in use in Australia at the time and it performed admirably. You can read the report yourself as it is available from the Archive
page and the Dairy Australia web site (A review of 11 applied dairy nutrition models used in Australia, 2009). The nutrition model in Rumen8 3 is unchanged from version 1.
