Ch.9 Animal Nutrition Flashcards
Nutritional management:
life stage
physical activity
state of health
Second most critical component after water
nutrients
Energy producing nutrients include:
proteins, fats, carbohydrates
Non energy producing nutrients include
vitamins, minerals, water
Kilocalorie (kcal, Calorie)
amount of heat required to raise the temp. of 1 kilogram of water 1 degree Celsius
Digestible energy (DE)
gross energy (GE) from food minus energy lost in feces
Metabolizable energy (ME)
-DE minus energy lost in urine and gas
-most common estimate of amount of kcal supplied from pet food
Net energy (NE)
ME minus energy used digesting, absorbing and using food
-Dietary source of nitrogen for animals
-Primary component of many tissues, enzymes, hormones
-Many other roles in the body
proteins
Proteins are made of
amino acids
Cats need _ essential amino acids
11
Dogs need _ essential amino acids
10
Biologic value (BV) is an expression of the amount of
essential amino acids in a protein
Animal sources of protein contain more essential amino acids than _ sources
plant
Cats need more _-based protein than plant based
meat
Rumen’s _ _ generates high quality protein from feed
microbial flora
Use of ___ in ruminants can cause toxicity
nonprotein nitrogen sources
Inexpensive source of energy, variety, fiber, palatability
Carbohydrates
Minimum requirement of carbohydrates for cats and dogs
none, there is no minimum
Overfeeding soluble carbs can lead to _
obesity
Soluble carbs are - extract or NFE
nitrogen free
Insoluble carbs are a
dietary fiber
What do insoluble carbs do
normalize GI tract, alter fat and glucose metabolism, decrease absorption of nutrients
Insoluble carbs can promote feeling of _
fullness
Insoluble carbs are inappropriate for:
young, pregnant and lactating, stressed, or working animals
Primary energy source in most commercial pet foods
fats
Fats provide:
palatability, fat-soluble vitamins A,D,E and K, essential fats acids (EFAs)
Fat deficiency signs
delayed wound healing
dry hair coat
scaly skin and skin infections
Vitamins functions and sources
-used in metabolic processes
-prevent deficiency syndromes
-found in animal and plant tissues, but some can be synthesized
-requirements differ among humans, dogs, and cats
Fat-soluble vitamins
A,D,E,K
fat soluble vitamins are stored in
fat and liver
Water soluble vitamins
B and C
Water insoluble vitamins are excreted with
water loss
Macrominerals
calcium, phosphorus, potassium, sodium, magnesium
Microminerals (trace)
iron, zinc, copper
Most important nutrient
water
water loss can result in _
death
Water intake in ml/day is roughly equal to __ requirement for cats and dogs
kcal/day
Palatability is influenced by
odor, temp, texture, mouth-feel, fat, water, salt
Digestibility
amount of nutrients in a food available for absorption after consumption
Digestibility is influenced by
quality of ingredients and processing technique
Nutritional assessment by vet tech
-take p history
-develop body condition score
-determine nutritional recommendations in conjunction with DVM
-Educate the client
Feeding method- portion controlled
(meal), specific amount at specific times, usually morning and evening
feeding method- time restricted
5 minutes of consumption , small and large breed dogs may need special consideration
feeding method- ad lib (free)
unlimited food is available and consumed at will, can lead to obesity, hard to monitor pets consumption
Resting energy requirement is
calories needed to maintain weight in controlled environment
