Q

What are the two methods of defending territory?

A
  • Overt aggression

Q

How do horses use signalling to mark territory?

A
  • Territories marked by olfactory cues
  • Wild/feral horses use manure piles along pathways which can actually separate bands of horses
  • In pastured horses, the stallion will actually back into an existing manure pile of his and eliminate there to create larger piles with his own scent

Q

How does individual space differ in hens?

A
  • Far away when walking
  • Closer when ground pecking
  • Even closer when standing
  • Closest when preening

depends on behaviour being preformed

Q

What are the four outlooks we use to establish space requirements?

A
  1. Economical - space required to achieve maximum economic return
  2. Biological - space required to achieve max productivity
  3. Affective state - space required to maximize positive and minimize negative behaviour
  4. Natural living - space required to allow birds to perform basic behaviours that they would be in the wild like nesting, perching, running
17
Q

How does varying space allowances affect cows?

A
  • Coat condition
  • Behaviour analysis (positive and negative)
  • Injury
  • Might include productivity - not always
18
Q

What is the definition of social behaviour?

A

Suite of interactions that occur between two or more individual animals, usually of the same species, when they form aggrigates, cooperate in sexual or parental behaviour, engage in disputes over territory and access to mates, or simply communicate across space

19
Q

What is territoriality in dogs or wolves?

A
  • In dogs, trigger factors can be territoriality, and others
  • In wolves, show signaling or aggression to other
    strangers or dogs within their territory - barking,
    growling, or stronger aggressive acts
  • More in dogs between 1-3 years old
  • Seen more in guard dogs

Signalling
* Barking
* Territorial call of dogs
* Used to defend a territory and demarcate its
boundaries

20
Q

Stray dogs which don’t have a real home rarely bark…. why?

A

keep attention away from themselves

21
Q

What is territoriality in cats?

A
  • Also exhibit territorial aggression
  • Sudden or explosive, with or without vocalization
  • Often initiated by smell
  • eye contact for signalling
22
Q

What do roosters do for signalling?

A
  • Crowing of roosters
  • Frequency associated with comb size (testosterone makes it more red and bigger)
    *
23
Q

How do we establish how much space animals need?

A

engineering standards
animal based standards
