Flight zones

What causes fear and aversion?
Give cows the choice between two handling techniques, and see which they AVOID
Shout!Nothing
“Y-maze”

Shouting is as aversive as an electric shock

Negative handler behavior
1. Handlers either behaved positively or negatively with cows
2. Brought cows into parlor
3. Each handler came into parlor
4. Measured physiological stress response of cows
![Page 14: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/14.jpg)
• Cows showed stress response when negative handlers entered the parlor
• Cows can recognize people, and can remember who treats them negatively
Negative handler behavior

How do cows recognize people?

How do cows recognize people?
Cows trained to push a lever and get food from one person (‘rewarder’)
Tested to see who cows would choose if:
Faces were visibleFaces were covered

Negative handler behavior
Hemsworth. 2000. Journal of Animal Science. 78:2821
Australian researchers visited 66 dairy farms and measured the amount of negative handling that cows experienced
![Page 20: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/20.jpg)
Negative handler behavior
Negative handler behavior correlated with: Cow fearfulness (measured by flight zone) Low milk yield Poor conception rates
Hemsworth. 2000. J Anim Sci. 78:2821
![Page 21: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/21.jpg)
When producers were given a course on animal handling:
They were less likely to use negative handling
They believed that cows were easier to handle
Cows produced more milk and had higher conception rates
Benefits of handling training
Hemsworth. 2000. J Anim Sci. 78:2821
![Page 22: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/22.jpg)
Low-stress handling
There are handling techniques that handlers can learn so they do not need to shout, hit, kick or prod the cows to get them to move
![Page 23: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/23.jpg)
Determining if a farm could benefit from training
LOOK AND LISTEN
![Page 24: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/24.jpg)
Look and listen to the cows
• Do they have large flight zones?• Do they look ‘on-edge’ or vigilant?• Do they quickly move away from you and
other people?• Do they slip/fall?• Do they ‘bunch’?• Do they vocalize?
![Page 25: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/25.jpg)
Look and listen to the handlers
• Do they hit/punch the cows?• Are they using a prod when it is not
necessary?• Are they yelling/cursing?• Are they banging objects together
to make loud noise?• Do they drag calves?• Do they seem like they don’t care
about the animals?
![Page 26: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/26.jpg)
If YES to any of those questions
• Handlers and their cows would benefit from handling training
• Training should teach skills, but should also impact attitude
• Moving cows using flight zone and point of balance• Avoiding negative behavior• Using herd behavior to move cows• Using positive reinforcement
Why should I care?
![Page 27: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/27.jpg)
Measuring flight zone
• Chose a sample of cows to measure• Slowly start to walk up to cows at the
feedbunk or in the pen (1 step/sec)• If cows are moving away when you are >~5 to
10ft away, they are likely fearful

NegativeBehavior
High fear
Low production
Handler behavior and animal welfare
Poor welfare
Hemsworth et al. (2000)
Negative attitude
![Page 29: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/29.jpg)
Improving attitude
• Improving skills can improve attitude and job satisfaction
• Owners should be aware of employees that do not care about the animals, or are not satisfied with their jobs
![Page 30: The Importance of Good Handling Skills for Dairy Cows](https://reader036.vdocuments.us/reader036/viewer/2022062902/58ee3a791a28ab9a488b460b/html5/thumbnails/30.jpg)
Action should be taken when…
• The employees could benefit from training• If you see something that you are not
comfortable with• If employee attitude is a problem
