Energy in Horse Feed
Friday, 24 February 2012 | Admin
In horses energy comes from the oxidizing of carbohydrate (fibre, sugars and starches), fat and to a lesser extent, protein from their diet or from their own body stores.
Energy is feed is calculated from its components so that the carbohydrate, fat and protein all contribute to its energy values.
Energy is measured in Mega Joules (MJ) per kg
I calorie = 4.18 joules
1 mega calorie (1,000,000 calories) = 4.18 Mega Joules (MJ)
A feed with an energy of say, 9 MJ / kg means there are 2,149,613 calories per kg of feed (or as we humans tend to measure calories, 2,149 kcal)
The following table gives typical energy levels of various horse feeds and where that energy is derived from:
