• General Comments
• DOGS AND CATS ARE CARNIVORES
• different nutrient needs from non-carnivores
  (especially protein)
• dogs can obtain nutrients from a wider range of
  foods than can cats
• plant materials difficult to digest for dogs and
  especially cats
• cats are obligate carnivores
• obligate carnivore some essential nutrients
  must come from animal tissue

NS
4

• WATER
• SOURCES
• from drinking water
• from the feed
• metabolic water (may meet 10-15 of requirement)
• CONSUMPTION
• 2-3 times more water consumed than feed dry
  matter
• FOOD FOR THOUGHT
• What factors affect how much water a dog or cat
  will consume?

5

• PROTEIN
• MOST COMMERCIAL DIET PROTEIN SOURCES
• animal tissues (what are some examples?)
• oilseed meals (what are some examples?)
• cereal grains (what are some examples?)
• insignificant source of protein
• GENERAL PROTEIN REQUIREMENTS
• maintenance dog 18-25 (DM basis)
• maintenance cat at least 25 (DM basis)
• growing animals higher
• producing animals higher

6

• CARBOHYDRATES
• usually starch
• inexpensive dietary component
• raw carbs not utilized well by dogs and
  especially cats
• lack enzymes for digestion
• excess consumption of raw carbs flatulence and
  diarrhea
• heat/moisture processing of carbs reduces effects
• cereal grains most common sources of carbs
• corn, wheat, rice, barley, (and potatoes)
• weight management diets have high fiber (up to
  30)

7

• LIPIDS (Fats and Oils)
• makes feeds more palatable
• source of essential fatty acids (EFAs)
• EFAs are linoleic, linolenic, and arachidonic
  acid
• increases energy content of diet
• important when feeding gestating, lactating,
  growing, or working dogs/cats
• source of fat soluble vitamins (A, D, E, K)
• helps with skin/coat quality
• most commercial diets
• Dogs 5-40 fat (DM basis)
• Cats 10-30 fat (DM basis)

8

• VITAMINS AND MINERALS
• See Textbooks

9

• VARIATION IN NUTRIENT REQUIREMENTS
• size
• age
• level of work
• environment
• repro status
• health
• activity level
