1
Q

types of carnivores

A

obligate 100% meat diet

hyper carnivore 70% meat diet

mesocarnivore 50% meat diet

hypo carnivore 30% meat diet

2
Q

Non-specialized Carnivores

A
eat vertebrate prey 
auto-enzymatic 
prey can provide
- balanced array of EAA
- good sources of fats, minerals, and vitamins
- not Ca unless eating bone 

physical properties
- strong jaws, teeth, beak, claws or talons

3
Q

Piscivores

A
eat fish 
auto-enzymatic
prey can provide
- balanced array of EAA
- good source of minerals and vitamins

provide highly variable fat content- depending on type of fish and climate

feeding techniques
- teeth, suction, filter, feeding

potential for toxin accumulation

4
Q

indigestible materials

A

bone and keratin

handled by

  1. separate before ingestion
  2. separate in the gizzard and eggiest as pellets
  3. not separated- although some bone is digestible
5
Q

Insectivores

A
eat insects
auto-enzymatic
insects provide: 
- balanced EAA
- good source P, trace minerals, vitamins
- fat content can be variable 

may eat plants for fat

Exoskeleton
- high calcium- low digestibility

Chitin

  • high indigestible
  • varies between species
  • animals will remove these parts or may have chitinase to break chitin down
6
Q

Microfaunivores

A
eat invertebraetes (that are not insects) 
auto-enzymatic digestion 
soft tissue similar to insects
- high digestible 
- high protein
- variable fat content 
may have to consider exoskeleton
7
Q

Grazers and Browsers

A
eat vegetative tissue
allo-enzymatic
microbial fermentation
plant material provide: 
- good balance of EAA
- low levels of Met and Lys 
- variable Na supply
8
Q

Nectarivores

A

eat nectar, honey and honeydew
auto-enzymatic digestion
highly digestible simple sugars
typically very low levels of EAA and EFA
- insects must be eaten to meet EAA requiremets

9
Q

Frugivores

A
eat fruits 
mainly auto-enzymatic digestion 
variable levels of: 
- energy 
-CP
- fat
- low Ca

may eat insects to supplement
seeds contained indigestible coat

handled by:
- chewing, cracking, gizzard grinding
