    Study Notes

    Water

    • Water is the most important nutrient
    • The requirement for water (in ml/day) is roughly 1.6 times the resting energy requirement (RER) for dogs and 1.2 times the RER for cats

    Carbohydrates

    • Carbohydrates include sugars and starches
    • This nutrient is utilized as a source of glucose
    • Carbohydrate ingredients include grains such as wheat, corn, rice, barley, and oats
    • Cooking increases the digestibility of carbohydrates

    Fiber

    • Fiber resists enzymatic digestion and is fermented in the colon
    • Promotes and regulates normal bowel function
    • Fiber sources differ in their fermentation properties
    • The amount of fiber in the diet impacts how much is fermented and how much is utilized
    • The amount of fiber in the diet impacts the amount of short-chain fatty acids (SCFAs) produced in the colon

    Minerals

    • Minerals are crucial for many bodily functions
    • Minerals from animal sources are more readily utilized than minerals from plant sources
    • A range of medical problems can result from mineral deficiencies or excesses

    Calcium

    • Deficiency: Decreased bone mineralization, bone fractures
    • Excess: Nephrosis, enlarged costochondral junctions

    Phosphorus

    • Deficiency: Pica, rickets, poor growth
    • Excess: Bone loss, calcification of soft tissues

    Potassium

    • Deficiency: Anorexia, heart and kidney lesions
    • Excess is rare

    Sodium and Chloride

    • Deficiency: Inability to maintain water balance
    • Excess: Thirst, seizures, death

    Magnesium

    • Deficiency: Muscular weakness, irritability, decreased bone density, seizures
    • Excess: Uroliths, paralysis

    Vitamins

    • Vitamins A, D, E, and K are fat-soluble vitamins
    • Intestinal absorption requires bile salts and micelle formation
    • Absorption occurs via passive transport
    • These vitamins are stored in fat, making deficiency less likely
    • More likely to cause toxicity than water-soluble vitamins
    • Remaining vitamins are water-soluble and are absorbed by active transport
    • Rapidly depleted, causing deficiency
    • Toxicity is uncommon

    Vitamin A

    • Deficiency: Anorexia, poor growth, weakness, fetal resorption
    • Excess: Tooth loss, poor growth, cervical spondylosis

    Vitamin D

    • Deficiency: Rickets, osteomalacia, bone fractures, enlarged costochondral junctions
    • Excess: Hypercalcemia, calcinosis, anorexia, lameness

    Vitamin E

    • Deficiency: Neurological dysfunction, myopathy (especially in dogs and cats with selenium deficiency)
    • Excess: Increased risk of bleeding, possibly due to interference with vitamin K metabolism

    Vitamin K

    • Deficiency: Bleeding disorders
    • Excess: Not typically observed, may contribute to calcium deposition in tissues

    Thiamin (Vitamin B1)

    • Deficiency: Cardiac dysfunction, neurological issues, gastrointestinal disturbances
    • Excess: Not typically observed

    Riboflavin (Vitamin B2)

    • Deficiency: Skin lesions, anemia, cataracts
    • Excess: Not typically observed

    Niacin (Vitamin B3)

    • Deficiency: Pellagra (characterized by dermatitis, diarrhea, and dementia)
    • Excess: Liver dysfunction, flushing

    Pantothenic Acid (Vitamin B5)

    • Deficiency: Growth retardation, hair loss, lethargy
    • Excess: Not typically observed

    Pyridoxine (Vitamin B6)

    • Deficiency: Neurological disorders, anemia
    • Excess: Neurological dysfunction, sensory neuropathy

    Biotin (Vitamin B7)

    • Deficiency: Skin and coat problems, lethargy, reproductive issues
    • Excess: Not typically observed

    Folic Acid (Vitamin B9)

    • Deficiency: Anemia, neural tube defects (in developing fetuses)
    • Excess: Not typically observed

    Cobalamin (Vitamin B12)

    • Deficiency: Poor growth, anemia
    • Excess: Altered reflexes

    Vitamin C

    • No signs of deficiency or toxicity observed in dogs or cats

    Choline

    • Deficiency: Thymic atrophy, poor growth, anorexia, fatty liver
    • Excess: No toxicity

    Carnitine

    • Deficiency: Cardiomyopathy, hyperlipidemia
    • Excess: No toxicity

    Energy Requirements in Dogs

    • RER (kcal) = 70 * (body weight [BW] [kg])^0.75
    • If BW is between 2 and 45 kg, RER (kcal) is approximately 30 * ( BW [kg])^0.75
    • MER depends on physiological state and ranges from 1.0 * RER in lower activity dogs to 3.0 * RER in highly active dogs

    Nutrition Unique to Cats

    • Cats are obligate carnivores; dogs are omnivores
    • Cats have lower liver glucokinase activity compared to dogs, making them less able to metabolize simple carbohydrates
    • Their body requires a higher percentage of animal-based protein than dogs
    • Cats have a higher requirement for arginine compared to dogs

    Nutritional Considerations in Dogs

    • Dog food should be formulated for specific life stages (e.g., puppy, adult, senior) and breed size
    • It is essential to choose a diet formulated for the specific needs of your dog and their lifestyle, including activity level and health status
    • It is recommended to select foods that have passed AAFCO (Association of American Feed Control Officials) feeding trials to ensure they meet nutritional standards
    • The "guaranteed analysis" on dog food labels should be reviewed to ensure it provides adequate information on the minimum percentages for protein and fat and the maximum percentages for crude fiber and moisture.

    • Commercial diets are typically balanced and provide a variety of essential nutrients. These diets should be selected based on the dog's age, breed, and activity level.
    • Homemade diets require careful planning and supplementation to ensure balanced nutrients.
    • Dogs requiring special dietary needs (e.g., allergies, weight management) may need specially formulated diets.

    Nutritional Considerations for Cats

    • Strict carnivore diet requirement: Cats need a high percentage of animal-based protein in their diet
    • Essential nutrients: Cats require taurine, arachidonic acid, and Vitamin A from their diet
    • Avoid high levels of simple carbohydrates and excessive amounts of plant-based protein sources
    • Choose foods with meat as the first ingredient
    • Cats have a higher fat requirement than dogs and should be fed a diet that meets this need.
    • Avoid feeding cats food designed for dogs, as it can lead to deficiencies
    • Dry food offers lower calorie density per volume than wet food. Some cats may struggle to meet their energy needs solely on dry food.
    • Wet foods are typically higher in moisture content and can be helpful for cats prone to urinary tract issues.

    Feeding Guidelines for Cats

    • Cats prefer to eat multiple small meals throughout the day
    • Allow for free feeding, but monitoring food intake is important
    • Indoor cats require less caloric intake compared to outdoor cats, but appropriate food selection is still crucial for health.

    Nutrition During Pregnancy and Lactation in Dogs

    • Increase calorie intake in late stages of pregnancy and during lactation, with a focus on energy density.
    • Enhance protein levels for fetal and puppy growth during pregnancy, with further increases during lactation.
    • Adequate hydration is crucial, especially during lactation.

    Nutritional Considerations in Specific Conditions

    • Conditions like obesity, diabetes, and kidney disease require specific dietary adjustments.
    • Consultation with a veterinarian is essential for proper dietary management.

    Nutrient Supplementation

    • Supplements should be considered only after consulting with a veterinarian.
    • Supplements should be used to fill nutritional gaps or address specific needs but not to replace a balanced diet.

    Homemade Diets

    • Homemade diets require careful planning and supplementation to ensure balanced nutrients.
    • Consultation with a veterinarian is essential to ensure the diet meets all the animal's requirements.

    Portosystemic Shunt

    • Protein should be from a highly digestible source
    • Protein content may need to be moderately restricted if signs of hepatic encephalopathy are present
    • Fat is an important source of calories

    Chronic Hepatitis or Cirrhosis

    • Hypoalbuminemia is a concern with hepatitis, and protein intake should be maintained at normal adult levels
    • If signs of hepatic encephalopathy are present, protein should be restricted
    • Adequate caloric intake is important to prevent tissue catabolism

    Dietary Changes

    • Gradual transitions between diets are recommended to allow the animal's digestive system to adapt.
    • Introduce new foods slowly over a period of days or weeks to minimize gastrointestinal upset.

    Feeding Strategies

    • Multiple smaller meals per day are beneficial for many animals, particularly those with a higher metabolism or digestive issues.
    • Feeding schedules can be adjusted based on the animal's individual needs and preferences.

    Water

    • Water is the most important nutrient
    • The daily water requirement is roughly 1.6 times the resting energy requirement (RER) for dogs and 1.2 times the RER for cats

    Carbohydrates

    • Include sugars and starches
    • Utilized as a source of glucose
    • Carbohydrate ingredients include grains such as wheat, corn, rice, barley, and oats
    • Cooking increases the digestibility of carbohydrates

    Fiber

    • Resist enzymatic digestion; is fermented in the colon.
    • Promotes and regulates normal bowel function
    • Fiber sources differ in their fermentation properties
    • The amount of fiber in the diet impacts bowel function

    Calorie content

    • The kcal/g of diet (metabolizable energy [ME]) is typically not provided on the pet food label
    • ME can be obtained either from product literature or directly from the manufacturer
    • Two diets can be quite different in terms of ME even if they appear similar in percentages of protein and fat
    • Diets should not be compared on the basis of percentages, but they should be compared using ME

    Calcium

    • Deficiency: Decreased bone mineralization, bone fractures
    • Excess: Nephrosis, enlarged costochondral junctions

    Phosphorus

    • Deficiency: Pica, rickets, poor growth
    • Excess: Bone loss, calcification of soft tissues

    Potassium

    • Deficiency: Anorexia, heart and kidney lesions

    • Dogs (omnivores) and herbivores can decrease this enzyme activity when low-protein diets are fed, but cats cannot.
    • Arginine is required in cats for the conversion of ammonia to urea. Arginine-deficient diets rapidly result in ammonia toxicity.
    • Taurine is required in cats due to their low rate of taurine synthesis. Unlike other species, cats can only utilize taurine for conjugation with bile acids.
    • Deficiency of taurine leads to central retinal degeneration, reproductive failure, and the development of dilated cardiomyopathy.
    • Taurine is abundant in animal tissues but absent in plants.
    • Methionine and cystine are sulfur-containing amino acids required in high levels by cats.

    Feline Nutrition

    • Zinc deficiency can occur in IBD, so assess zinc consumption
    • Omega-3 fatty acid supplementation may be beneficial
    • Feed multiple small meals per day

    Antioxidant Vitamins

    • Antioxidant vitamins such as vitamins E and C may have benefit to prevent lipid peroxidation

    Feline Hepatic Lipidosis

    • Provision of adequate calories is most important
    • Many cats are fed via feeding tube

      • Discontinue oral intake of food and water until vomiting stops. Provide parenteral nutrition if necessary.
      • Avoid excess dietary protein because free amino acids can stimulate pancreatic secretion. Maintain adequate protein ingestion
      • Ensure adequate water intake
      • Feed a diet low to moderate in fat
      • Limit dietary protein to one or two sources.

    Cancer

    • Cancer cachexia is an important issue.
    • Chemotherapy and radiation therapy may impact the ability to consume food.

    • A variety of medical problems can result from deficiency or excess of minerals.
    • Minerals from animal sources are more readily utilized than minerals from plant sources.

    Vitamins

    • Vitamins A, D, E, and K are fat-soluble vitamins.
    • Intestinal absorption requires bile salts and micelle formation; absorption is by passive transport.
    • They are stored in fat; thus deficiency is less likely; however, they are more likely to cause toxicity.
    • The remaining vitamins are water soluble and are absorbed by active transport.
    • They can be depleted, rapidly causing deficiency; toxicity is uncommon.

    Vitamin A

    • Deficiency: Anorexia, poor growth, weakness, fetal resorption
    • Excess: Tooth loss, poor growth, cervical spondylosis
