The MS Excel spreadsheets at the following link contain essential tools for evaluating your horse’s caloric intake versus requirements and determining the likelihood of a laminitic episode. Use the link below to go to the site, and right-click on the appropriate MS Excel file to download and save it to your computer. Don’t attempt to open it directly; it won’t work! There are two versions listed: a 2007 version for the typical newer PC, and a 97-2003 version for the Mac and older versions of MS Excel. There are no macros in them, but I’ve protected them to ensure no corruption of the data or formulas, which is why they won’t open directly within the browser.
