Small Animal Nutrition Flashcards
6 Essential Nutrients
Small Animal
- Protein
- Carbohydrates
- Fats
- Water
- Minerals
- Vitamins
Protein
- Made up of essential vs nonessential amino acids
- Forms hormones and enzymes
- Excess used for energy - not as efficient as other energy sources
- Cats require more than dogs - more used for energy
Essential Amino Acids
Must be present in order to make proteins
Essential Amino Acids
Cats
- Taurine
- Arginine
Nonessential Amino Acids
Can be created if not available in the body
Carbohydrates
- Primary function is energy
- Soluble vs Insoluble
- Digested through GI tract
- Used in the form of glucose - stored as fat if not used
Carbohydrates
Soluble
- Digestible
- Consist of monosaccharides and disaccharides
- Supply calories to diet and used immediately for energy
Carbohydrates
Insoluble
- Indigestible
- Consist of polysaccharides
- Portion of plant that does not digest and provides fullness and bulk to diet
Fats
- Most concentrated source of energy
- Enhances taste and calories
Fats and Vitamins
Fats required for vitamins A, D, E, and K for
* absorption
* transportation
* storage
EFAs
Essential Fatty Acids
* building blocks of fat
* saturated vs unsaturated
* maintain skin and coat
EFAs
Saturated vs Unsaturated
- Saturated = long carbon chain without double bond
- Unsaturated = one or more double bonds
EFAs Required for
Normal Metabolism
- Linoleic Acid
- Arachidonic Acid
Water
- Most essential nutrient required for survival
- Makes up 70% of the body
- Required to absorb vitamins B and C
Minerals
- Total percent in body is less than 1%
- Essential for metabolic processes
- Macro vs micro minerals
Macrominerals
- Expressed in percentages
- Help to maintain elecrolyte and water balances, bones and muscles, and nerve and cellular function
Microminerals
- Expressed in parts per million (ppm)
- Also known as trace minerals
- Involved in biochemical reactions
Vitamins
- Function as enzymes
- Classified by solubility
- Requirements can vary by species
Vitamins
Water-Soluble
Vitamin B complex and C
* none stored in body
Vitamins
Fat-Soluble
Vitamins A, D, E, K
* stored in fat or liver
* excess can be toxic
Vitamins
Cats
- Require vitamin A
- Require vitamin B naicin - used to convert tryptophan
Energy Units
RER
Resting Energy Requirement
* 30 x (weight in kg) + 70
Energy Units
MER
Maintenance Energy Requirements
* energy factor multipled to RER
* also called DER (daily)
Feeding Method
Free Choice
Food available at all times
* animal decides when and how much
* good for those who meet energy requirements without exceeding
* recommended during lactation
Feeding Method
Time-restricted Meal Feeding
Unlimited food available for a certain period of time
* generally given over 10-30 minutes
* easier to see if food is eaten or not
* pets develop routine - important to keep regular schedule
Feeding Method
Food-restricted Meal Feeding
Specific quantity of food given at specific times
* best feeding method
* actual measurements of calories
* beneficial for digestive disorders or those prone to them
Nutritional Requirements
Gestation and Lactation
- Similar to neonates
- Feed a high-quality, highly digestible growth diet
- Begin diet few weeks towards end of gestation
- Transition back after weaning
Feeding
Neonates
- Nursing should be done at least 4-6 times per day
- Weigh every 2 weeks to ensure proper growth
Feeding
Weaning
- Begin around 3 weeks of age, but can be sooner; finish by 5-8 weeks
- Food should be mixed with water to make a gruel
- Feed 3-4 times per day
Nutritional Requirements
Large Breed
- Pregnant / lactating should eat a growth diet, but not a large breed one
- Vitamin D required - helps with calcium and bone cell activity
- Recommend food-restricted feeding
AAFCO
Association of American Feed Control Officials
* establishes a standard of nutrition
* regulates use of terms for calorie and fat contents
* statements based on feeding trials
Enteral Nutrition
- Given orally
- Coaxing methods used to entice animal to eat
- Appetite stimulant drugs can also be used
- Use of tubes to assist feeding can be alternatives
Parenteral Nutrition
- Nutrition given by direct IV infusion
- Use of central or peripheral catheters
- Done when enteral is either not productive or counterindicated due to illness
FDA
Food and Drug Administration
* regulates what info needs to be on pet food labels
