Reproductive Unit Test Key
Animal Science-Reproductive Midterm and Project
Overview
Reproduction Unit Objectives: By the end of this unit, students will be able to…
- Identify the following from both images of the reproductive tract as well as by their descriptions: uterus, vulva, oviduct, cervix, and vagina.
- List the causes of reproductive inefficiency in livestock.
- Compare and contrast natural and artificial insemination.
- Explain how each of the following change during estrus: vulva; oviduct; vagina; ovary.
- Identify and explain the purpose (if any) of each of the following cervical structures:
a. Fornix b. Annular Rings c. Mucus Plug
- Identify and explain the purpose (if any) of each of the following uterine tissues:
a. Perimetrium b. Myometrium c. Endometrium d. Caruncles
- Identify and explain the purpose (if any) of each of the following regions in the oviduct:
a. UTJ b. Isthmus c. Ampulla d. Infundibulum
- Identify and explain the purpose (if any) of each of the following ovarian structures:
a. Ova b. Follicles c. Corpus Luteum
- List and describe the signs of estrus in a cow.
- Summarize the causes, symptoms, and implications of each of the following disorders:
a. Ovarian Cyst b. Anestrus c. Freemartin d. Blind/Closed Cervix e. Dystocia f. Metritis
g. Retained Placenta h. Anestrus i. Uterine Prolapse j. Vaginal Prolapse k. Repeat Breeding
- Define and describe each of the following: a. Estrous Cycle b. Endocrine Gland c. Target Tissue d. Estrus e. Endocrine System
- Summarize how a hormone “knows” which tissues and organs to activate.
- Explain why two messenger systems are needed in the bodies of animals.
- Identify, describe, and explain the function of GnRH, FSH, LH, Estradiol, Progesterone, and PGF2α.
- Identify GnRH, FSH, LH, Estradiol, Progesterone, and PGF2α based on when the reach their peak levels in the estrous cycle.
- Explain the purpose, mechanism, and hormonal components of Lutalyse, Ovsynch, CIDR, and MGA.
- Summarize and explain each of the following stages of the estrous cycle:
a. Estrus b. Metestrus c. Diestrus d. Proestrus
- Explain the difference between a paracrine and endocrine hormone.
- Explain the difference between insemination and conception.
- Identify the window of time in which a cow should be bred after calving.
- Determine when it is appropriate to breed a cow by recognizing the signs of a cow in heat.
- Summarize the function of each of the following heat detection aids: heat expectancy chart, mount detection aid, tailhead markings, heat detector animals, and pedometers.
- Identify when insemination should occur based on when a cow is seen in heat.
- Summarize the purpose, function, use, and limitations of the following pregnancy detection methods: rectal palpation, ultrasounds, and blood testing.
- Compare and contrast the benefits and drawbacks of twinning in cattle.
- Summarize and define each of the following terms: dry period, lactation, gestation, and mastitis.
- Summarize the steps necessary to dry off a cow and prevent mastitis during or after the dry period.
- Diagnose a case of mastitis based on its symptoms.
- Diagnose whether or not a cow is about to calve based on her symptoms.
- Summarize the signs of normal calving vs. abnormal calving and diagnose whether or not human intervention is necessary.
- Summarize and explain the steps required to conduct a physical exam on a cow while she is calving.
- List the situations in which human intervention during calving will always be necessary.
- Explain the proper intervention methods during the following scenarios: upside down calf, backwards calf, calf with a head/leg bent backwards, calf that is positioned correctly but has not made any progress in at least 30 minutes.
- Summarize how to manually dilate the cervix of a cow to aid in calving.
- Demonstrate how to properly utilize and apply calving chains in order to assist with cases of dystocia.
- Demonstrate how to properly care for the cow and the calf after calving in order to ensure maximal health and prevent disease and infection.
