Animal Reproduction scenarios

You go visit a family member for Easter Vacation and you mention you are in the animal science class. They have questions for you. Answer their questions with factual details and specific examples. Draw them a picture if needed.

1. Your friend wants to breed her dog that she paid a lot of money for. You notice the dog has an overbite in it’s jaw, a genetic trait. What do you think? Explain to your friend a smart decision.

2. I heard that mares are especially receptive to stallions during the winter months, as they really like the long nights. Is this true? What have you learned in your class?

3. Isn’t Estrus and Estrous the same thing? Please explain…

4. Your friend has a cow that is pregnant. Describe what signs they should watch for to know the cow will deliver it’s calf soon

5. Describe the purpose of the umbilical cord and placenta

6. Isn’t sperm and semen the exact same thing? Explain.

7. Explain where fertilization of the egg takes place in the female reproductive system AND where the fetus actually grows until it is born.

8. Your friend is preparing to breed her mare. What are some signs of “heat” or estrus she should watch for?

9. What does the term “short day breeder” refer to? Explain.

10. Your friend bred her ewe almost a month ago, but she is seeing signs of “heat” or estrus in the ewe again. Use your knowledge of the estrous cycle to explain to your friend if her ewe is pregnant and how you can tell.
