|
Ingredients are listed in descending order by weight. Each ingredient must be shown. Listed on “As is” basis, official names and definitions.
|

Supposedly raw food provides extra enzyme needed by pancrease which improves digestability
(update) |
|
How to calculate food dose?
|
Dose = energy requirement (kcal/day) / energy density (kcal/can) = can/day
Basically want complete, balanced diet, but only feed waht animal needs! Requirements for non-energy nutritientss are automatically met |

|
Conditions caused by poor diet
|
Obesity
– Progression of renal disease – Developmental orthopedic disease/ skeletal disease (canine) – FLUTD (feline): Feline Lower Urinary Tract Disorder – Dental disease |
|
Risks with free choice
|
- over-nutrition e.g. too much calcium or vitamin D, orthopedic disease (in dogs)
- obesity |
|
Feline Lower Urinary Tract Disorder caused by
|
1. Bladder Stones, AKA Uroliths: These take the form of crystals of struvite or calcium oxalate. Too much ash, or pH of urine too high
2. infection |
|
Free choice?
|
-can use as long as only getting what they need
-dry/semidry better |
|
RER
|
-“resting energy requirement”
-does not support activity - RER (kcal/day) = 70 (BWtkg)^0.75 *use ideal body weigh 30(BWtkg) + 70* (*when BWt is 2 to 45 kg) |
|
food dosage and ambient temperature
|
generally caloric intake higher during winter
In some places burn more calories when really hot, panting |
|
DER =
|
daily energy req = RER x factor
DER = 205 kcal/day × 1.8 = 369 kcal/day |
|
• All-purpose foods
|
: “womb to tomb,” one product satisfies all nutritional needs in all situations, food consumption is based on caloric needs. Not a valid concept.
|
|
• Specific-purpose food
What are some specific purposes? |
- different life stages (growth, adult, geriatric)
-body condition/use (obese-prone adult, athletic/working dog, gestation, lactation) |
|
Nutritient
|
Any food constituent that helps support life
|
|
Key Nutrient Factor
|
Key nutritional factors (KNF) are the main nutrient requirements for feeding different life stages and purposes. Encompass nutrients of concern and other food characteristics.
They include: 1. energy/fat: energy intake determines growth intensity. Risk of DOD INCREASES in large breeds with energy- dense well balanced foods b/c grow too fast and get abnormal growth. However, some fat important for vit. absorption. 2. Calcium: growing dogs will absorb 90% calcium are fed. DOD is signif. higher in young, giant-breed dogs being fed food containing excess calcium (e.g. 3.3% DMD), regardless of normal phosphorus ratio. Hence, there is danger in feeding these fast growers adult maintenance foods (to decr. energy intake) or calcium supplements, because calcium level will be too high. 3. digestibilty - goal is high quality (digestible), in low density package Others: soluble carbohydrate (reduce Cu abs), Zn, I, Cu, Ph 4. Encompass nutrients of concern and other food characteristics. |

|
Most common analysis done for
nutritional testing What does it measure? |
Proximate Analysis
Crude fat, crude protein, moisture, crude fiber & ash - carb. (NFE) calculated by subtracting all these from 100% Not very accurate |
|
More accurate way to determine nutrient components in food?
Most accurate way to determine what animal needs (energy requirements)? |
Average Nutrient Analysis: More accurate than proximate
analysis Calorimetry - measurement of heat |
|
1. How does cat maintain blood glucose lvl between meals?
2. Does cat produce glucokinase? |
1. Cat doesnt get big spike in blood glucose level after meal like humans do, b/c can't produce large amounts of active hexokinases (which brk down
Cats maintain blood gluc. betw meals via gluconeogenesis, breakdown of AA and fats from glycerol 2. No (only tiny bit, but not active), but does produce other 3 non-inducible, constitutive hexokinases. From online: "Gluconeogenesis is the production of new glucose in the body from non-sugar sources, mainly proteins. It occurs mainly in the liver and kidneys. It is major body energy source for cats, who lack the glucokinase that let other animals synthesize glucose more rapidly after eating. Cats use another enzyme called hexokinase, which is not very efficient, for processing carbohydrates. Gluconeogenesis happens slowly and steadily, in each cell of the body. cats are able to maintain fasting blood glucose (by converting protein to glucose) even without a meal, but must be eating a high protein diet on a regular basis to be able to do so. An unrelated process, glycogenolysis, releases stored glucose very fast by breaking down glycogen in liver (Glucokinase (GK) is a isozyme of hexokinase, so not the same) |
|
identify basics behind gluconeogenesis (challenge question)
|
metabolic pathway that results in generation of glucose from non-CHO source such as lactate, glycerol, and glucogenic amino acids.
one of two main mechanisms many animals use to keep blood glucose levels from dropping too low (hypoglycemia). Other being degradation of glycogen (glycogenolysis). |
|
Glucose 6-phosphatase (challenge question)
|
enzyme that hydrolyzes glucose-6-phosphate resulting in creation of phosphate and free glucose.
Glucose is then exported from cell via glucose transporter membrane proteins.[1] This catalysis completes final step in gluconeogenesis and glycogenolysis and plays a key role in homeostatic regulation of blood glucose levels. |
|
Cats higher ___ vitamins then dogs.
Where foound? Digestibility? what else does do they require as far as vitamins go? |
B-vitamins (B1, B6, 5xNiacin, folate)
Found green beans, vegetable oil, but mostly biologically unavailable A-vitamins - more specifically require retinoic acid, because cant convert B-carotine (vegetable form) to Ret.Acid (animal form) like humans and dogs can. It is found in animal livers! Also require tryptophan and/or Nicotinic Acid (vit B3)(converted into dopamine) - this is niacin Also require vitamin D, cant get from sun. From animal tissue, fat, liver of mice. |
|
Mineral requirements for cats?
What to avoid excess of? |
similar to dogs.
need Ca, dont eat bones. Require Cu danger of Mg, causes Struvite (ammonium magnesium phosphate) crystals. readily soluble in acid. Struvite urinary stones and crystals form readily in urine of animals and humans that are infected with ammonia-producing organisms. They are potentiated by alkaline urine and high magnesium excretion (high magnesium/plant-based diets). |
|
Ideally when to spay/castrate cat?
What changes afterwards? |
6 months
energy requirements go way down, |
|
Vitamin often deficient in cat food, required for good growth?
|
VItamin A!!!!!

only unique are sodium and chloride, antioxidants, food texture
and as usual energy density, protein, fat, fiber, calcium and phosphorus, |
|
What to feed cats?

|
What changes made in older cat diet?
|
kidney function decreases, so
do NOT on all-growth all-life stage diet. Want to keep eye on potassium!!!! If low, can adversely affect kidney, want to keep Ca/Ph, NaCl down Sell Ca stones in older cats, not Mg stones like see in younger cats |
|
Is excess protein a threat to growing giant breed dogs?
|
No, but overconsumption and fat/energy dense foods are bad
|
|
Why dont u want to give pregnant dog more calcium?
(more information needed) |
There is no scientifically established nutrient profile for older dogs. Assess individual patient’s needs. Avoid nutrient excess.
