Spartan Dairy 3 is a Windows-based, stand-alone computer program for use in evaluating and formulating diets for dairy cattle. It was designed to formulate reasonable diets in a relatively short period of time using the latest science. The current version is 3.0.3 (August, 2011). It will work on Macintosh computers using a program like Parallels.
This web site is designed to give an overview of the product, provide a demonstration version of it, and help you use it effectively.
To purchase a copy, see "How to Order" for pricing and purchase options.
To try a fully-functioning demonstration version of the program, go the "Demo Download". The demo version will work for 120 days after downloading. Files and library feeds will continue to work after it expires if you purchase the program. This will give you a chance to see if you like it before spending the money. If you are using for instruction, see info in "How to Order"; we also have a demo version that will last longer.
A few bugs still exist. Please read about these in the "Current bugs in the program" page. The major bugs are that vitamin A requirement is higher than needed if working in pounds, and you will get errors when printing diets with more than 4 wet feeds. These two bugs will eventually be fixed. In addition, some things do not work as we had hoped. Notes do not print out in reports, nor can you insert your own logo in reports. We make no promises about these.
