Nutrition Exam #1 Review (Junior yr/Sem 1)

Why is nutritional assessment essential at every veterinary visit?

because nutrition is the foundation of health and disease prevention

How can increased veterinary technician involvement in nutrition consultation improve patient health outcomes?

more technician led nutrition consults -> better owner compliance -> improved health

What is the difference between open-ended and closed-ended questions when taking a diet history? Provide one example of each

open ended: encourages detailed, narrative answers

-ex: "pretend I'm your pet's sitter..."

closed ended: specific, structured, avoids yes/no

-ex: "who feeds the pet"

Why is it important to identify who in the household is responsible for feeding the pet?

to detect inconsistent feeding, double feeding, or emotional feeding patterns

List three important questions to ask about a pet's diet

-commercial or homemade?

-is human food added?

-brand consistency?

Why should a structured diet history form be used?

it ensures consistency, completeness, and easy online access if made available online

What percentage of the diet can be fed as treats?

treats should be

What are two risks of excessive treat or table food feeding?

-excess calories

-may interfere with disease management

How might treats interfere with the management of chronic conditions like renal or cardiac disease?

they add unbalanced nutrients (phosphorus, sodium, fat) that contradict therapeutic diets, making conditions like renal or cardiac disease harder to control

Identify two historical risk factors and two physical risk factors for nutritional problems

Historical:

-GI dysfunction, existing medical condition

-raw/home/vegetarian diets

Physical:

-abnormal BCS/MCS

-weight loss/gain >/= 10%

According to the AAHA guidelines, why is unintended weight loss of >/= 10% considered significant?

it indicates a meaningful change in health status and is a physical risk factor for malnutrition

What is the concern when pets are fed raw, homemade, or vegetarian diets?

they are listed as nutritional risk factors due to imbalance, contamination, or inadequate nutrient profiles

Besides body weight, what other components are essential in assessing body comopsition?

-fat vs lean mass

-BCS

-MCS

Name two clinical signs that may suggest malnutrition

-skeletal malformation

-coat/skin changes

What is the main focus of BCS scoring?

BCS evaluated body fat, not muscle

What BCS scoring scale is universally used in veterinary medicine?

the 9-point system

How can hair coat and breed affect the accuracy of BCS assessment?

they can hide or exaggerate fat coverage, making scoring more subjective

What approximate percentage of body fat corresponds to a BCS of 8 in a male dog?

40%

Which anatomical areas are evaluated in the MCS system?

-temporal muscles

-scapula

-lumbar vertebrae

-pelvis

-sagittal crest, scapular spine, spinous process, wing of ilium, greater trochanter

What does a score of 0 indicate on the MCS scale?

severe muscle wasting

What is "Overcoat Syndrome" and why is it important to recognize in sick cats?

fat and hair coat hide muscle loss, especially in sick cats

According to WSAVA, what questions should you ask about a pet food manufacturer?

-does the manufacturer employ veterinary nutritionists?

-where is the food production facility located?

-where are ingredients sourced?

-are there quality control measures in place?

-is the company willing to share a full nutrient analysis?

Why is it important to know whether a company employs veterinary nutritionists?

it indicates expertise in diet formulation, safety, and evidence-based nutrition

What is the difference between an AAFCO adequacy statement based on formulation and one based on feeding trials?

formulation: "formulated to meet..." (recipe meets nutrient profile on paper)

feeding trial: "animal feeding tests using AAFCO procedures..." (tested on live animals)

What specific wording on a pet food label indicates that the product meets AAFCO feeding trial standards?

"Animal feeding tests using AAFCO procedures"

List the steps veterinary technicians should perform during a nutrition consult

1. assessment and history

2. determine ideal weight

3. calculate food dose

4. discuss plan with owner

5. make specific recommendations

6. recheck monthly

7. follow-up

Why should client/patient monthly rechecks be part of the nutrition consult process?

to monitor progress, adjust calories, reassess BCS/MCS, and maintain compliance

How does making specific recommendations improve client compliance?

clear, actionable instructions reduce confusion and increase owner confidence, making them more likely to follow the plan

Why are pet food labels considered a mix of science-based information and marketing?

because labels contain regulated, scientific information (nutrient adequacy, guaranteed analysis, ingredients) alongside marketing terms meant to influence buyers

How do pet owners' perception of labels influence veterinary practice and pet care?

high owner interest (90% read labels; 84% want more info) means vets must understand labels to guide clients, correct misconceptions, and prevent nutrition-related mistakes

What organizations regulate pet food labels in the US? What is the difference between their roles?

FDA: basic regulatory oversight- product ID, ingredient listing, net quantity, manufacturer info

AAFCO: provides specific standards, nutrient profiles, label formatting, adequacy statements

State/Government/OISC: enforces feed laws at the state level

What is the Uniform State Feed Bill, and whats its purpose?

a model law adopted by stated to ensure uniform regulation of animal feeds, including pet food

List three pieces of information that must appear on the principal display panel (PDP)

-product name

-species to be fed

-net quantity in package

What information must be included in the guaranteed analysis?

-protein (min %)

-fat (min %)

-fiber (max %)

-moisture (max %)

Why is the ingredient list potentially misleading when comparing food quality?

ingredients are listed by weight, including water content- so fresh meats appear first even though they may contribute less protein than dry ingredients

What are two methods used to substantiate nutritional adequacy on pet food labels? Which method is considered more reliable, and why?

-"formulated to meet AAFCO nutrient profiles..."

-"animal feeding tests using AAFCO procedures..."

feeding trials are more reliable because they test the diet on live animals

What does complete and balanced mean?

-contains all required nutrients

-in proper proportions

-can be fed as the sole ration for the life stage

How are veterinary therapeutic diets labeled differently from standard foods?

they may be labeled: "for intermittent or supplemental feeding only"

What is the legal definition of "natural" on a pet food label?

no chemically synthesized ingredients, except vitamins/minerals. No artificial flavors, colors, preservatives

How much of a diet must be organic for it to be labeled "organic"?

->/= 95% organic ingredients for the USDA organic seal

->/= 70% for "made with organic ingredients"

Why should terms like "holistic" or "human grade" be interpreted with caution?

they have no legal definitions and are purely marketing

What are by-products, and how can they contribute to nutrition?

secondary products from processing that provide amino acids, vitamins, minerals, and palatability

Why can comparing pet food on an "As Fed" basis be misleading?

moisture dilutes nutrients- wet foods appear lower in protein/fat unless converted to dry matter

Convert the following: A canned diet with 10% protein (AF) and 78% moisture. What is the percentage on a Dry Matter basis?

DM = 100-78 = 22%

10/22 x 100 = 45.45% protein DM

Why is dry matter basis important for comparing diets?

it removes moisture differences so nutrient levels can be compared accurately

How do inaccurate feeding directions contribute to obesity risk in pets?

feeding guidelines often overestimate caloric needs, causing chronic overfeeding and weight gain

How can veterinary technicians use labels to support client education about nutrition and weight management?

technicians can explain:

-what "complete and balanced" means

-how to interpret guaranteed analysis

-how to identify marketing vs regulated info

-how to compare diets using DM

this improved nutrition and weight-management compliance

If a pet food label states it is "complete and balanced," what additional information would you need to determine if it is appropriate for a specific pet?

-life stage

-method (formulation vs feeding trial)

-calorie content

-suitability for medical conditions

A pet owner wants to feed their dog "organic" food. What key points would you discuss with them?

-must be >/= 95% organic to carry the seal

-organic does not equal nutritionally superior

-organic diets can still be high calorie or unbalanced

-cost considerations

A pet owner wants to feed their cat only "homemade" food. What key points would you discuss with them?

-high risk of nutrient imbalance

-must be formulated with a board certified nutritionist

-requires precise recipes and supplements

-risk of contamination or unsafe ingredients

How might misleading marketing claims on labels impact both owner expectations and pet health outcomes?

owners may choose diets based on emotion rather than science, leading to:

-nutrient deficiencies

-poor disease management

-overpaying for diets that don't meet their pets' needs

Resting energy requirements are based on what?

RER is based on the energy needed to carry out essential body functions at rest

What calculations provide an estimate of energy use?

The three RER formulas:

-linear formula: (30 x BWkg) + 70

-cube root formula

-allometric formula: 70 x (BWkg)^ 0.75

Why is allometric formula used most often?

because it is most accurate, works for all weight ranges, and is widely accepted

What does ME mean?

metabolize energy- the usable energy available to the animal

What does kcal mean?

kilocalorie- the unit used to measure energy in pet food

What conditions can affect DER calculations?

-life stage (growth, adult, gestation, lactation)

-activity level

-disease states (pancreatitis, CHF, kidney disease, FLUTD)

What values do you need to calculate the feeding volume for an animal?

-RER or DER

-diet's ME (kcal/kg or kcal/can)

-pet's weight

What is the difference between lipid and dry measuring cups? Why does it matter which is used to measure food?

-liquid measuring cup: 8 fl oz (fluid volume)

-dry measuring cup: 8 oz (dry volume)

using the wrong one leads to incorrect portions and overfeeding

What % of the diet should be fed as treats?

How does BCS/MCS relate to the determination of RER/DER?

BCS/MCS guide whether calories should be increased, decreased, or maintained

What does AABW (listed on your card) mean, and why is that important for puppy energy requirements?

average adult body weight- used to determine correct puppy DER factors

What is DOD? Which breeds are at risk, and why?

developmental orthopedic disease- large and giant breeds are at risk because they require controlled growth

What is the difference between nutrients and ingredients in pet food?

Nutrients: chemical compounds the body needs (protein, fat, vitamins, etc)

Ingredients: the identifiable components of the food (chicken, rice, beet pulp)

List the six categories of nutrients

-water

-protein

-fat

-carbohydrates

-vitamins

-minerals

Why is water considered the most vital nutrient?

because it supports cellular function, digestion, nutrient absorption, and waste removal

How do saturated and unsaturated fats differ, and what are essential fatty acids (EFA)?

-saturated fats: solid at room temp

-unsaturated fats: liquid at room temp

-essential fatty acids: omega-3 and omega-6 fatty acids the body cannot synthesize

What are amino acids, and why are some considered "essential"?

-amino acids are the building blocks of proteins

-essential amino acids cannot be synthesized by the body and must be supplied in the diet

Compare simple carbohydrates, complex carbohydrates, and dietary fiber

-simple carbs: sugars

-complex carbs: starches (polysaccharides)

-dietary fiber: soluble (fermentable) and insoluble (non-fermentable)

Distinguish between fat-soluble and water-soluble vitamins. Provide examples of each

-fat soluble: A, D, E, K

-water soluble: B-complex, C

Define the difference between macrominerals and microminerals

-macrominerals: needed in large amounts

-microminerals: needed in small amounts

What is the significance of nutrient bioavailability?

bioavailability determines how well nutrients are absorbed and used by the body

What factors can affect ingredient quality in pet foods?

-whole vs meal

-processing method

-nutrient form (natural vs synthetic, chelates)

Define metabolize energy (ME)

energy the body can actually use after subtracting losses in heat, urine, and feces

How is resting energy requirement (RER) calculated?

RER = 70 x (BW)^0.75

How is daily energy requirement (DER) calculated, and what factors influence it?

DER = RER x life stage/activity factor

influenced by: growth, gestation, lactation, activity level, disease state

Why is energy balance important in companion animals?

to prevent excess or deficiency, both of which lead to disease

Compare processing methods: dry, wet, raw, dehydrated, and freeze-dried

-dry: extrusion, baking

-wet: canning, pouching

-raw: ground, crushed, fresh/frozen

-dehydrated: dried with heat

-freeze-dried: freezing + sublimation

How does processing method affect nutrient availability?

heat, drying, and extrusion can reduce some nutrients; freeze-drying preserves more; raw may have variable digestability

What role does dietary fiber play in digestion and satiety?

-soluble fiber: fermentable, supports gut health

-insoluble: increases fullness, fecal bulk, motility

Explain the concept of nutrient synergy. Provide an example

-nutrient enhance each other's absorption or function

-example: pre/probiotics + fiber improve digestion

How do prebiotics and probiotics contribute to diegstive health?

they support beneficial gut bacteria and improve digestion and nutrient absorption

Why is it important to maintain proper nutrient ratios in a diet?

imbalanced nutrients (e.g. Ca:P) can cause disease or poor absorption

What makes cats obligate carnivores, and how does this affcet their dietary needs.

they cannot efficiently derive essential nutrients from plants and require higher protein

Why are dogs considered facultative carnivores/omnivores?

they can synthesize essential nutrients from plant sources

Why is it incorrect to assume that "cats are just small dogs" when formulating their diets?

cats have different digestive systems, nutrient needs, and metabolic pathways

Which life stages are recognized by AAFCO? Which are not recognized?

-recognized: growth, adult maintenance, gestation, lactation

-not recognized: senior

What nutrient concerns are more important during growth in dogs and cats?

-higher protein

-higher fat

-balanced vitamins/minerals

-Ca:P ratio (dogs)

Why is the calcium-to-phosphorus ratio critical in large breed puppies?

to prevent developmental orthopedic disease (DOD)

What crude protein and fat levels are recommended for growing dogs and cats?

dogs: protein up to 22% DMB, fat up to 8% DMB

cats: protein up to 30% DMB, fat minimum 9% DMB

What are the key nutritional needs for adult maintenance in dogs and cats?

dogs: about 18% protein, about 5% fat

cats: >/= 26% protein, >/= 9% fat

During gestation, why should additional calcium supplements not be provided?

they increase risk of hypocalcemia and disrupt natural regulation

How do energy requirements change during gestation and lactation?

energy needs increase 30-60% above maintenance

When does peak lactation occur in dogs and cats, and how does this affect nutritional needs?

peak lactation: 3-4 weeks postpartum

requires free-choice feeding and high nutrient density

What are the nutritional strategies for feeding senior pets despite AAFCO not defining this life stage?

-adjust calories

-modify protein, phosphorus, sodium

-increase fiber

-manage disease

At what age are small vs large breed dogs considered senior?

small breeds: >/= 7 years

large breeds: >/= 5 years

At what ages are cats considered mature, senior, and geriatric?

mature: 7-10 years

senior: 11-14 years

geriatric: 15+ years

What are the risks and benefits of feeding diets labeled "all life stages"?

benefits: convenient, meets highest nutrient needs

risks: may exceed needs for adults/seniors -> obesity or nutrient excess

How do you determine if a pet food is appropriate for a given life stage based on the nutritional adequacy statement?

-growth

-maintenance

-gestation/lactation

-all life stages

Why might a food formulated for "all life stages" not be ideal for a senior pet

it is formulated for growth, meaning higher calories, protein, and minerals that seniors need
