Feed calculations

• calculate carbs:

  1. carbs = 100%(protein+fat+moisture+ash+fibre+calcium+phosphorus)
• Calculate energy content per gram
• calculate energy content per gram

  • total energy per 100 grams= proteins+ fat+ carbohydrates
• To compare the nutritional value of dry and wet foods only look at the dry content
• Example to work out the dry part in wet food (example protein)

  • 30% of protein/ (100-moisture content %)
  • 30%/(100-10%)
  • 30%/90%
• RER = (weight in kg x 30)+70
• Daily serving = energy requirement of animal/ energy supplied by 100g of food stuff
