UNIT DIRECTORY: ___________________________________________________________________________ Code Topic Title hours year(s) ___________________________________________________________________________ (CLF231) Natural Selection 2 2 (CLF232) Parturition 3 1 / 2 (CLF233) Showmanship 2 1 / 2 TOTAL TIME FOR UNIT = 7 Hours ______________________________________________________________________ UNIT GOAL: Students shall UNIT OBJECTIVES: Upon completion of this unit, the students will be able to: 1. Define Evolution. 2. Define (genetic) variability. 3. Define natural selection. 4. Discuss how variability and natural selection work together to "change" an animal species. 5. Discuss how natural selection and genetic variability may be manipulated by man in order to produce disease resistant livestock. 6. Identify (from slides) those livestock breeds which are naturally heat resistant, as well as crossbreeds of those livestock and the benefits of these crosses. 7. Define "parturition." 8. Discuss the events leading to, during, and after parturition. 9. Observe first-hand (or through the use of videotape) the birth process, making note of events previously discussed in class. 10. Actively participate in the training of sheep, hogs, or cattle for the purpose of demonstrating their marketable qualities, including: a. Halter Breaking b. Proper use of show sticks and canes c. Fitting for presentation d. Leading and presenting to a judge ______________________________________________________________________________ REFERENCES: Introduction to Environmental Science (Moran/Morgan/Wiersma); trait comparison of cattle (included).

RESOURCES: Local Ranchers or dairy people (for live demonstration of parturition) Local exhibitors, 4-H leaders (none if you're a "show jock" yourself); local ranchers to "donate" livestock for fitting and showing; see resource section for a list of companies that have fitting and showing presentations available (if you want to supplement with slides, etc. or don't have livestock available to you).
