Lecture 2

Front 1

_____ and _____ are closely interrelated

Back 1

Feeding Behavior; Digestive Track

Front 2

Carnivore GIT

Back 2

• simple GI tracts w/ little microbial activity
  
• require certain nutrients, such as pre-formed vitamin A and taurine
  

Front 3

Herbivore GIT

Back 3

• Complex digestive tract
  
• symbiotic microbial activity that permits the digestion of plant fiber

Front 4

Free-Choice Water (Ad-libitum)

Back 4

water that is clean, accessible and will be preferred by an animal

Front 5

What limits Free-Choice Water?

Back 5

• Inadequate water supply
• Contaminated Water

Front 6

Palatability

Back 6

Summation of taste, odor, appearance, texture and temp. of feed that determine its degree of acceptance.

(affected by chemical or physical nature of feed)

Front 7

Chemical Factors effect Palatability

Back 7

• Taste
  
• Odor (lesser)
• Secondary compounds - toxins that protect plants

Front 8

Physical Factors that effect Palatabilty

Back 8

• Texture
• Particle Size - decrease particle size gen. increase feed intake (larger surface area in overall feed)

Front 9

Expenditure of energy

Back 9

large amounts of energy expenditure by an animal will generally result in an increase of feed consumption

Front 10

Who consumes greater feed quantities of feed per unit body size?

Back 10

What is young or mature lactating animals?

Front 11

Larger animal consumes _______ feed per unit of body weight

Back 11

less

Front 12

Thermo-neutral zone (TNZ)

Back 12

The metabolic rate of an animal is at a minimum when environmental temperatures are in a range that no energy demand is made on the body temp. regulating mechanisms

Front 13

Environmental Temp beyond comfort zone:

As temp increases beyond comfort: _______

As temp decreases beyond comfort: _______

Back 13

1. animal consumes less feed
2. animal consumes more feed

Front 14

Specific Dynamic Action (SDA)

Back 14

refers to the extra heat produced by the animal as a result of feed ingestion and the metabolism of its nutrients

Front 15

Heat increment (HI)

Back 15

is the sum of SDA and the heat of rumen fermentation

Front 16

Feed consumption can be reduced by health of animal

Back 16

Like:

1. metabolic problems (bloat, diarrhea etc.)
2. STRESS (Crowding, handling and noise)
