Q

what is the order of feedstuff to be mixed

A

feedstuff that makes up majority should be mixed first
slowly add wet ingredients to avoid clumping
add any ingredient that makes up less than 2.5% of the ration

19
Q

what are other factors that may affect feed intake

A

temperature, pregnancy, conditioning, body size, smell, illness and fatigue

20
Q

what makes up palatability

A

taste, olfaction, and texture

21
Q

define feed preference test

A

one animal is fed 2 foods and whichever it eats most of is the most preferred food

22
Q

describe dissension feedback

A

relies on stretch receptors in the stomach to stop the brain from eating more

23
Q

describe low energy diets

A

requires more food to fill up the stomach, so is often used for weight loss

24
Q

describe chemostatic feedback

A

signals to satiety centers that animal has enough energy and can stop eating
glucose, VFAs

25
Q

what does energy concentration determine

A

voluntary feed intake

26
Q

what do NDFs do for forage composition

A

measures the true fiber in the stomach

27
Q

what does high NDF cause

A

more time in the rumen for digestion

28
Q

what does low NDF cause

A

more fibers feedstuff

29
Q

what layers does the rumen contain

A

gas
forage mat
and grain/yesterdays feed

30
Q

describe what feed intake in monogastrics can be affected by

A

essential amino acids

31
Q

describe what feed intake in ruminants can be affected by

A

the bypass protein and nitrogen

32
Q

describe the bypass protein

A

does not go through microbial digestion

33
Q

to produce more, what do animals need to do

A

eat more

34
Q

define comfort zone

A

doing nothing extra to maintain body temp; metabolic rate is at a minimum

35
Q

define heat increment

A

extra heat produced due to metabolism of a nutrient

36
Q

what has the highest heat increment and why?

A

metabolism, nitrogen

37
Q

what does more protein cause

A

more heat production

38
Q

what does feed intake decrease during late digestion?

A

because there is less room in the stomach

39
Q

why does feed intake increase during peak lactation?

A

to continuously produce milk

40
Q

define conditioning

A

what experience an animal has with certain food

41
Q

define neophobia

A

fear of new foods

42
Q

define aversive conditioning

A

training animals not to eat certain foods

43
Q

higher metabolic rate=?

A

higher feed intake and energy

44
Q

metabolic body size=

A

BW^0.75

45
Q

how can smell affect feeding

A

certain odors, whether from the food or not, may cause food to become unpalatable to an animal

46
Q

how can fatigue affect feeding

A

animals may become fatigued in seeking, ingesting, chewing, and ruminating feed

47
