Dog and Cat nutrition Flashcards
What is Gross energy
The total energy in food, measured by combustion in a bomb calorimeter and burn- heat given off = max possible energy in food
What is digestible energy?
The energy absorbed into the body after digestive processes
GE - energy lost in faeces
Why isn’t digestible energy the sum total energy of what a dog or cat can use?
Because the macro nutrient protein is harder to get energy from- need to deaminate the amino acid (remove N = urea), rest can be used. This process requires energy.
What is metabolisable energy
DE - energy lost in urine
The energy within a food that a dog and cat can utilise
What do you need to know to use the Modified Atwater Factors to work out the metabolisable energy
protein % (from tin label)
Fat % (from tin label)
Carb % aka nitrogen free extract (work out, rarely given)
How to work out the carb % is not given.
What is moisture isn’t listed?
Carbohydrate% = 100 - (protein% + fat% + Crude fibre % + Inorganic matter % (ASH) + moisture).
If moisture not lsited, assume 10%
When know the % of each component what do you do next to work out the metabolisable energy.
What unit is this ME per?
You multiple the % by the aformentioned modified atwater factors:
P = 3.5
C = 3.5
F = 8.5 (most energy dense macronutrient)
BECAUSE % = PER 100g food!!!!
