Q

What are the primary characteristics of the main types of conventional pet foods?

A

Pet food is a total mixed ration, supplying all nutrients except water. It is complete & balanced, meaning nutrients are providing in proportion to energy—so that nutrient requirements are met when caloric needs are met. Some commercial products are NOT complete & balanced, however. Instead, they are labelled for “intermittent or supplemental feeding only,” i.e., not complete & balanced, or not tested. This can include canned products and includes many treats. Pet food nutrients include

30
Q

What is AAFCO? What does it do?

A

Association of American Feed Control Officials (AAFCO) is a non-governmental organization that sets guidelines for uniform labelling and nutritional adequacy. In America, each State sets separate pet food regulations, but AAFCO guidelines form the basis of these regulations in every state, bar two (Nevada and Alaska).

31
Q

Is compliance with AAFCO guidelines mandatory?

A

No. It is voluntary

32
Q

In regards to labelling regulations, AAFCO compliance involves what? (7)

A

oProduct name, Net weight, and the words “dog food” or “cat food”
oName & address of manufacturer
oGuaranteed analysis (CP, crude fiber, crude fat, moisture)
oIngredients listed in ↓ order by weight
oCaloric content per common unit of measure
oDirections for feeding
oStatement of nutritional adequacy or purpose

33
Q

According to AAFCO regulations, what is NOT available on food labels?

A

Overall digestibility, biologic value of protein, quality of product, contamination

34
Q

Besides determining labelling regulations, what else does AAFCO do?

A

*Establishes standard nutrient profiles, e.g., for growth, maintenance, etc.
*Establishes standardized feeding trial protocols.
*Defines feed ingredients.

35
Q

What methods are used by pet food manufacturers to prove product nutritional adequacy?

A

1.Computer Analysis to meet AAFCO profiles.
2.Standardized AAFCO feeding trials

36
Q

How do pet food manufacturers use Computer Analysis to prove product nutritional adequacy?

A

Estimates concentrations of nutrients and identifies serious formulation errors, HOWEVER assumes ingredients used have the same nutrient profiles as the computer database. Nutrient content is then confirmed by chemical analysis.

37
Q

Describe Standardized AAFCO feeding trials

A

A specific animal type and number undergo a trial length as determined by label claim, whereby defined clinical observations are recorded and there is an established criteria for passing or failing – Nutrient content is then confirmed by chemical analysis

38
Q

Why could one argue food trials are better than computer analysis? Include what sort of information you can gather

A

Provides indirect information regarding factors unable to be evaluated by chemical analysis alone on the following:
oPalatability
oNutrient digestibility & availability
oNutrient interactions
oToxins & contaminants

39
Q

What is the Family Product Rule?

A

Manufacturers can claim on labels that a product has passed AAFCO feeding trials without testing when the product is similar to “parent food,” provided laboratory tests prove they match or exceed key ingredients—also, claims must match those of the “parent food” in terms of animal life stage, e.g. Adult Dogs.

40
Q

What is a sign that your animal is consuming an acceptable diet (from a nutritional standpoint)?

A

oMaintain BW and condition.
oGood coat quality
oNormal stool

41
Q

How can you objectively evaluate the quality of a commercial pet food? (7)

A

*AAFCO feeding trials are most reliable and objective assessment. GOLD STANDARD.

*Animals consuming acceptable diets:
oMaintain BW and condition.
oGood coat quality
oNormal stool

*Animal protein should be high on the ingredient list.
o1 of first 2 for cats

*Check for added calcium.

*Be suspicious of different forms of the same ingredient listed separately.

*Digestibility >75% to be considered adequate → Does the animal have diarrhea?

*Quality of packaging.

42
Q

What are the pros and cons of grain-free foods?

A

Pros:
* Corn has an incomplete amino acid profile - lysine, methionine, tryptophan are limited.
* Wheat has an incomplete amino acid profile (lysine, methionine, and threonine are limited).
* Wheat is one of 3 common causes of food hypersensitivity in dogs (secondary to gluten)
* Same quality assessment as any other pet food

Cons
* Very few documented cases of corn hypersensitivity or intolerance
* Corn & wheat are well utilized by dogs.
* Grain-free diets are ↑ fat and protein.
o Predispose to obesity.
o Poor choice for hepatic/renal insufficiency, fat intolerance, or pancreatitis
* Protein is $$$ source of energy (dollar costs & metabolic costs)
* Dilated Cardiomyopathy in Goldens
* Taurine deficient dogs (inconsistent)

43
Q

What are the pros and cons of raw foods?

A

Pros:
* Some are TMR fed as sole source of nutrition.
* Many now formulated to meet AAFCO profiles.
* True risk of infection is poorly defined, as few reports give cause & effect.
* Pet-food borne infection is not limited to raw food.
* Careful client education can improve outcomes, e.g.:
o Safe food handling; do not feed pets in kitchen.
o Avoid poultry products.
o Not on immunosuppressive drugs.
o Informed consent?

Cons:
* No evidence for “evolutionarily appropriate” claim → refuted by genomic comparison of dogs to wolves
o Dogs digest starch better
* GI foreign bodies and perforation
* Gastroenteritis from bacterial contamination or ↑ FAT CONTENT
* Sepsis
* Iatrogenic hyperthyroidism
* Nutritional imbalances, especially when prepared at home.
* AAFCO guidelines weren’t developed for raw food.
* Risk of infection in cats & dogs! Salmonella, E. coli, Listeria, Staph sp., toxoplasmosis, & Campylobacter

44
Q

What is metabolizable energy? Include equation

A

Metabolizable energy (ME) is gross energy in food after subtracting energy lost in feces and urine, i.e. it is the total energy available to animal.

ME = Energy[intake] – (Energy[urine] + Energy[feces])

45
Q

What is maintenance energy requirement?

A

Maintenance energy requirement (MER) meets needs for:
*Basal metabolic rate
*Normal body temperature
*Recovery from normal activity
*Obtaining, digesting, and assimilating food

46
Q

how do we calculate maintenance energy requirements?

A

MER = 110 (BWkg)^3/4

47
Q

When do we use equations annd tables in nutrition?

A

to provide a rough estimate of individual requirements – an initial recommendation of food intake.

48
Q

How do you feed a healthy cat to maintain optimal body condition?

A

*30% of calories from protein (high!)
*Absolute requirement for TAURINE & ARGININE
*Cannot synthesize arachidonic acid – require animal fats.
*↓ capacity for Vitamin D synthesis
*Cannot convert carotene → Vitamin A (retinol)
*Cannot convert tryptophan → niacin.
*Energy requirements are poorly defined
*50-80 kcal ME/kg/d
*Nutrient requirements met when caloric requirements are met.

FEEDING RECOMMENDATIONS:
*Meal or ad lib feeding of canned or dry all good – Obese cats better with meals!
*Different ration types as needed!
*NO supplements
*5 kg cat → 290 kcal

49
Q

How do you feed a healthy dog to maintain optimal body condition?

A

*Discourage use of vitamins and mineral supplements
*Meal feeding is most appropriate (twice a day or once a day)
*Different ration types as needed.
*Treats should be no more than 10% of caloric intake.
*Canned products can be associated with dental disease.
*Dry food is convenient and costs less for large breeds.
*Owner/pet preference matters most.
*25 kg dog → 940 kcal
*45 kg dog → 1460 kcal

50
Q

In general, when instructing an owner on How to feed a healthy cat or dog to maintain optimal body condition, what should you keep in mind?

A

BE CLEAR AND SPECIFIC
– Identify product names, flavours, and forms; - provide several choices to account for cost and availability;
- Provide exact amounts in familiar measurements (cups/cans)
- Give written instructions
- Update medical record to reflect changes.

51
Q

How should feeding practices be adjusted for geriatric dogs? Include feeding recommendations.
