TSS notes
HISTORY -I used this talk at a Select Sires repro symposium. It was well received.
ATTENDEE’S –this worked well for a group of technicians, should work very well at producer type meetings
LENGTH –The talk ran right at 1 hour for slides 0-61. There is a section on the end that you can use if you have 2 hours to present.
NOTES –I have included notes you can view if you select normal view in the lower left corner or your screen.
EXTRA SLIDES -There are a couple of places there are two slides that could cover the same topic. I usually hide one of them.

Stress and Dairy Cow
Stress: External event resulting in strain on the biological system. It is measurable.
Collier, 2002
Stress and Dairy Cow
A cow under stress has a weaker immune system than a cow not suffering stress.
A cow under stress produces less milk than a cow not under stress.
A cow under stress has a higher basal metabolic rate than a cow that is not under stress.
A cow under stress has a higher blood cortisol level than a non-stressed cow.

Which cows are stressed?
How do cows respond to stress?
