Answer 9

True

Question 10

Answer 10

Neonatal

Question 11

Question 12

A. The foal is dead and he should arrange a funeral service

B. You didn’t specialize in horses and thought you were being called out for a sick cow so you have no idea what is going on

C. The foal is sleeping and most likely in the transitional phase of development

D. The foal is sleeping and should probably be weaned soon

Answer 12

C

*In the transitional phase it is normal for foals to lie down during REM sleep and the mother to have a ‘recumbency response’ (stand nearby her foal who is lying down)

Question 13

During the socialization phase (~4 weeks) young foals will begin to display gender differences. How are the interactions of fillies different from colts?

Answer 13

Fillies: Chasing and grooming

Colts: Chasing, mock fighting, mounting

Answer 14

True

Question 15

Describe the weaning process that would naturally occur with horses?

Answer 15

Begins at 6-12 months and is a gradual process where the foal will come and go for several weeks before leaving for good. Often weaning isn’t complete for 2-3 years.

Question 16

True or False:

Colts will often stay with their natal band after reaching sexual maturity (~12 mo +)

Answer 16

False

*While it is not uncommon for a fillie to join the existing harem a young colt will often feel pressured by the harem stallion to leave the natal band and join a bachelor band or form a new harem

Question 17

What was the take home message regarding the study that was discussed that talked about imprint training in horses?

Answer 17

Although early handling made the horses easier and safer to work with in the long run the standardized imprinting procedure within the first few hours of birth wasn’t necessary and the horses showed no improved response to specific stimuli

False

*Social maturity not usually achieved until 1-3 years of age (~2x sexual maturity)

Question 20

What would you advise an owner to do with her new puppies during the neonatal phase of development that will help improve disease resistance, decrease emotional reactivity and increase learning and problem solving?

Answer 20

3 min of handling per day + exposure to temperature change

Question 21

What developmental stage in puppies and kittens begins with opening of eyes and ends when their ears are fully open (onset of acoustic startle)?

Answer 21

Transition

Question 22

True or False:

Short periods of handling from birth to 5 weeks for puppies and kittens will increase nervous system maturation stimulate more hair growth and result in increased weight gain?

Answer 22

Question 23

What specifically defines the socialization period of development for puppies and kittens?

Answer 23

All senses are functioning so as to facilitate learning and communication
