AN 238 - Dairy Reproductive Technologies

3 Credits
Outline Effective Date: 2019 Fall Version #1
Created: Mar 13, 2019 Approved: Sep 30, 2019

Lecture Hours: 45

Course Description:
This course covers the anatomy and physiology of the male and female reproductive system of dairy cattle. Topics include hormones and control of male and female reproduction, puberty, estrous cycles, ovulation, fertilization, pregnancy, parturition, reproductive disorders and biotechnology used within the industry.

Rationale:
This is a required course for the Dairy Science major of the Animal Science Technology program for second year students. Since reproductive efficiency is a major factor influencing profitability in the dairy industry and the maintenance of healthy animals, students receiving training in related programs must be especially competent in this area of study.

Prerequisites: None
Corequisites: None

Course Learning Outcomes:
Upon successful completion of this course, students will be able to

identify structure, location, and function of component parts of the reproductive systems for dairy cattle.
describe the processes involved in successful reproductive performance on dairy operations.
outline and explain the management strategies to improve reproductive efficiency.

Required Resource Materials:
Required Textbook(s):

Senger, P. L. (2015). Pathways to pregnancy and parturition (3rd revised ed.). Current

Conceptions, Inc.

Reference Textbook(s):

None

Optional Resource Materials:
None

Conduct of Course:
This course consists of 3 hours of lecture per week.

The lecture is a formalized classroom situation where the instructor discusses pertinent topics and the students normally follow the lecture material using the textbook as a reference.

Attendance

Classroom and laboratory attendance is considered vital to the learning process and as significant to the students’ evaluation as examinations and reports, therefore absenteeism is recorded.

Students having a combination of excused and/or unexcused absence of 20 percent or higher for the scheduled course hours can be required to withdraw and would then automatically receive a “RW” (required withdrawal) for the course, regardless of any other evaluation results. (RW is a failing grade).
An excused absence is one that is verified with your instructor. Verification should be prior to the absence or the next class day following the absence. Verification of the absence may take the form of a note from your doctor/College nurse regarding illness, or a note from another instructor regarding a field trip or other activity, or authorization by your instructor following an in-person meeting. Be sure to contact your instructor and ask what they will require from you as verification for each absence. An unexcused absence is anything NOT verified by the instructor prior to the absence or the next class day following the absence.

NOTE: Any exceptions to the above attendance policy (e.g. timetable conflicts, work-related issues) must be approved in writing by the Department Chair prior to the beginning of the course.

It is the students’ responsibility to know their own absentee record.

Normal hours are 8:30 a.m. to 6:30 p.m., with potential for evening courses, exams or extended field trips. Students are expected to be available for classes during these times.

Course Assessments:

Tests	40%
Assignments, Projects & Quizzes	25%
Final Exam	35%
Total	100%

Missed Exams:

If, for any reason, a student is unable to write one of the scheduled exams, the weight of that exam is transferred to the Final Exam, as long as the instructor is given at least one week notice prior to the exam. This policy also is applied to exams missed due to illness as long as a doctor’s note is provided. A “make-up” exam is not arranged.

Here at Lakeland College, we acknowledge that the land we gather on is the traditional homeland, hunting, and ceremonial gathering places of the First Nations, Métis and Inuit. The Plains Cree, Woodland Cree, Saulteaux, Blackfoot, Métis, Dene, and Nakota Sioux people have practiced their culture and languages on Treaty 6 and Métis Region 2 territories for generations and were the original caretakers of this land. Many First Nation, Métis and Inuit peoples call this land home today and have done so for millennia. We would like to acknowledge the history we have created together on this land, and to be thankful for the opportunity to walk together side-by-side in friendship, learning from our past, and promoting positive relationships for the past, present and future.
