Q

Postures and movement of CATTLE at rest

A
  • During the day, rest in STERNAL RECUMBENCY while ruminating
  • May rest without ruminating
  • While not actively grazing, may stand at rest without ruminating; loafing time is variable, but short in healthy cattle
  • In daylight lateral recumbency is less than 1hr

Q

Ruminants have extensive periods of drowsiness usually associated with what?

A

- Drowsy state for about 7-8hrs/day divided into 20 periods or more that precede and follow sleep

Q

How are rumination and sleep inversely related?

A

Sternal resting increases but sleep decreases as the percentage of roughage in the diet increases
- more forage = more rumination = more drowsiness = less sleep

Q

Respiration is tied to…

A

Movement!
- O2 consumption increases linearly in a running animal
- Net cost of running is constant for each species (decreases with increasing body size)

Q

The system of kinetic behaviour has…

A

Range, rhythm and pattern
- innate in origin, being a feature of the species
- innate kinetic drive is modified by diverse factors

18
Q

What is ambulatory kinesis incorporated into?

A

Grazing
- grazing rhythms described as kinetic rhythms
- kinesis is a prominent component of play behaviour

19
Q

What is Taxis?

A
  1. Locomotion either directly towards or away from a source of stimulation
  2. Locomotory behaviour involving a steering reaction
  3. The spatial correction movement resulting in orientation
20
Q

What is Thigmotaxis (Thigmotropism)?

A

Behaviour revealing a drive to make and maintain close bodily contact with an associate animal

21
Q

What is termed a ‘gait’?

A

In locomotion, when the limbs act synchronously in any one of a variety of patterns

22
Q

What are 2 forms of gait patterns?

A
  1. Symmetrical
    - The movements of limbs on one side repeat those of the other side, but half a stride later
    - eg. walk, pace, trot
  2. Asymmetrical
    - The limbs from one side do not repeat those of the other
    - ev. cantor gallop, lope and rotary gallop
23
Q

What is a stride?

A

The full cycle of movement of a leg during the support propulsion and flight phases

24
Q

What is stride length?

A

The distance covered between successive imprints of the same hoof

25
Q

If each limb strikes the ground separately the gait will be a…

A

4-beat gait
- If diagonal limb pairs (eg trot), the gait is 2-beat
- Cantor is a 3-beat gait in waltz time
- Gallop resembles the cantor but since it is faster, it has an extra “floating phase”

26
Q

What are 13 factors influencing feeding behaviour?

A
  1. Circadian characteristics
  2. Social factors
  3. Biological sensors
  4. Rate of ingestion
  5. Rate of digestion
  6. Nutrient density or dilution
  7. Palatability
  8. Intake depressants
  9. Intake stimulation
  10. Feeding interference
  11. Food selectivity
  12. Experience
  13. Type of animal
27
Q

Consideration: herbivores vs omnivores; ruminants vs monogastrics

A

Factor influencing feeding behaviour: Type of animal

28
Q

Consideration: daily feeding patterns are affected by environmental conditions such as season and characteristics of food supply

A

Factor influencing feeding behaviour: circadian characteristics

29
Q

Consideration: competition and related dominance characteristics; feeder space and operational characteristics; pasture and rangeland

A

Factor influencing feeding behaviour: social factors

30
Q

Consideration: taste and olfactory sensors; chemoreceptors for plasma glucose levels, insulin production and cholecystokinin

A

Factor influencing feeding behaviour: biological sensors

31
Q

Consideration: reflects animal’s capacity to find and consume food; ratio of fibrous feeds to higher-energy concentrates such as grains

A

Factor influencing feeding behaviour: rate of ingestion

32
Q

Consideration: influences feeding frequency and duration; greater variation in ruminants

A

Factor influencing feeding behaviour: rate of digestion

33
Q

Consideration: reduced nutrient density leads to animals eating more total feed; limited by capacity of digestive tract

A

Factor influencing feeding behaviour: nutrient density or dilution

34
Q

Consideration: Rejection of off-flavoured foods; preferences for sweet flavours; salt intake impacts as well

A

Factor influencing feeding behaviour: palatability

35
Q

Consideration: achieving BW set point; high environmental temp; high estrogen level; gut distention

A

Factor influencing feeding behaviour: intake depressants

36
Q

Consideration High lactation yield; high grow rate; cooler temps; implants

A

Factor influencing feeding behaviour: intake stimulation

37
Q

Consideration: climatic influences, presence of predators, spoilage, disease

A

Factor influencing feeding behaviour: feeding interference

38
Q

Consideration: ability to select higher-energy, more nutritious foods

A

Factor influencing feeding behaviour: food selectivity

39
Q

Consideration: learning and follow others in feeding (eg location of resources)

A

Factor influencing feeding behaviour: experience

40
Q

What 8 factors affect grazing behaviour?

A
  1. Animal species
    - anatomical differences
  2. Forage quality and quantity
    - interact to minimize grazing time and distance covered
  3. Time of day
    - graze longer periods right after dawn and late evening, shorter period midday; patterns altered by thermal conditions
  4. Season and weather conditions
    - cold reduces early and late day grazing periods; heat reduces or eliminates midday grazing
  5. Insect annoance
    - infestation of flies shortens grazing times and increases time spent standing in water if available
  6. Scheduling
    - milking times, riding times, and other management schedules
  7. Efficiency of harvesting
    - stage of plant growth, physical condition, travel distance, etc
  8. Plant population composition
    - animals select safest, most nutritious plants and plant parts; overgrazing and high animal density limit selection
41
Q

Water

A
  • Accounts for 50-80% of the animal body
  • Relates to acid-base balance and heat regulation
  • Requirements increase with heat and lactation
  • In sheep and cattle, a significant relationship exists between dry intake and water intake
  • Pigs and poultry may increase water intake if feed restricted
