Motivation

• Early diagnosis of health issues

• To find welfare consequences of changes in housing and management

Stress

• The more rest thay have

the less stressed they are

• Symptoms of stress

▫ aversion to lying down

▫ breathing and heart rate acceleration

▫ reduction in the quantity of milk and its protein content and fat

Measurement

• 10 indoor-housed beef cows

• 16 days of measure

• 10,814 lying ‘episodes’

• Video recording

IceTag sensors

Checking every minute

Clearing episodes

• Lying more than 4 min

▫ Lying behaviour

• Lying less than 4 min

▫ Interruption

▫ 88% of episodes

▫ 3% of total lying time

Discovery nr 1

The longer a cow has been lying down,

the more likely that cow will soon stand up

Discovery nr 2

Once a cow stands up,

you cannot easily predict how soon that cow will lie down again
