Energy producing nutrients Flashcards
(16 cards)
7 basic nutrient groups
Water
Protein
Fat
Carbohydrate
Fibre
Vitamins
Minerals
Basal Metabolic Rate (BMR)/Basal Energy Requirement (BER) calculation (animals 2-50kg)
kcal = (30 x bodyweight in kg) + 70
Resting Energy Requirement (RER) calculation (any size animal)
kcal = 70 x (bodyweight in kg) to the power of 0.75
Maintenance energy requirement calculation
kcal = ((30 x bodyweight in kg) + 70) x 2
Only 3 nutrients that have any energy value
Protein
Carbohydrate
Fat
Proteins
Made up of chains of amino acids
Cats needs are especially high
Use of amino acids
Synthesis of new proteins
Energy production
Amino acid essential for cats
Taurine
Biological value (BV)
How much of the protein can be absorbed and used
Triglycerides
3 fatty acids bound to a glycerol molecule
Polysaccharides
Made up of several rings/chains of carbon, hydrogen and oxygen atoms
Starch
Broken down when digested to release glucose
Cellulose
Indigestible to monogastrics (organisms with one stomach)
Source of dietary fibre or roughage
Disaccharides
Two linked rings/chains of carbon, hydrogen and oxygen atoms
Monosaccharides
A simple ring/chain of carbon, hydrogen and oxygen atoms
Oligosaccharides
A few linked rings/chains of carbon, hydrogen and oxygen atoms
