Unformatted text preview: ANS 3319C – Spring 2012 Reproductive Physiology and Endocrinology in Domestic Animals Instructors: Dr. Joel V. Yelich Office: Room 125h Animal Science Bldg. E- Mail: yelich@ufl.edu Office Hours: Open & by appointment Voice: 352- 392- 7560 Web Page: www.animal.ufl.edu/ans3319/ANS3319C.htm Lecture: Monday, Wednesday, & Friday (Period 4) 10:40 - 11:30 AM, Animal Sciences Room 156 Course Objectives: 1) Familiarize students with the reproductive anatomy, physiology, & endocrinology of male & female domesticated animals including the cow, pig, horses, sheep, cats, dogs, birds, and humans. 2) Introduce and discuss the interrelationships between reproductive hormones produced by the brain and reproductive glands and how they interact to control the reproductive processes of male and female domesticated animals including the cow, pig, horses, sheep, cats, dogs, birds, and humans. 3) Utilize the knowledge learned from Objectives 1 and 2 to introduce and discuss reproductive management practices that optimize reproductive efficiency of domesticated animals and humans. Textbook: Pathways to Pregnancy and Parturition (2nd Revised Edition 2005, P. L. Senger) is required since we will lecture directly from it in addition to extensive use of pictures & diagrams. We will provide copies of lecture notes and they will also be on the web page. There is a copy of the textbook on reserve in the Marston Science Library on main campus. A Lab Notebook will be distributed the first week of class and they will also be posted on the course web page. Students are responsible for reading handouts before lab and bringing handouts to lab. Grading & Exams: Your final grade will consist of lecture exams, lecture quizzes, lab exercises, and a comprehensive final exam. Actual grades on all exercises will be the sum of the points received for correct responses as a percentage of total points possible. Final course grades will be based on the following percentage grade scale: A A- ≥ 94 ≥ 90 to < 94 B+ B B- ≥ 87 to < 90 ≥ 83 to < 87 ≥ 80 to < 83 C+ C C- ≥ 77 to < 80 ≥ 73 to < 77 ≥ 70 to < 73 D+ D D- ≥ 67 to < 70 ≥ 63 to < 67 ≥ 60 to < 63 E < 60 Final Grade Components Three lecture exams (100 pts each) & four quizzes (25 pts each) Lab grade (50 pts per lab; two lab exams worth 200 pts each) Comprehensive final exam (200 pts) Information regarding University Policy on grade point equivalencies and calculation of grade points is located at the following web address (http://www.registrar.ufl.edu/catalog/policies/regulationgrades.html). Lecture Exam Dates: # 1: Feb. 6 Exam/Quiz questions will be true/false, multiple choice, matching, short answer, and essay. For short answer and essay questions, a legible, organized, concise and grammatically correct answer will be expected in order to receive full credit; although, partial credit will be given. Outlining answers into pertinent points is acceptable and the suggested method of answering questions, provided that the interrelationships between points are indicated. Request to re- grade an exam/quiz must be made within one week from date exam and (or) quiz is returned in lecture or lab. Grade challenges must be submitted in writing, attached to exam/quiz, and returned to instructor or TA. Students must clearly outline why they believe that they should be given additional points. The instructor reserves the right to re- grade the entire exam. Lecture exams/quizzes will cover material presented in lecture, textbook, as well as take- home messages, and worksheets completed in lab. A student missing an exam will be allowed to make up the exam provided that a documented, valid reason for missing it exist (Please see valid excuses in lab section). Whenever possible, these problems should be discussed with the instructor in advance, preferably by email, excuse note, or hand written note. A missed exam with no valid excuse will be considered as a “0”. Course Expectations: Lecture and lab attendance are highly correlated with your final grade so it is expected that you attend both on a regular basis. Additionally, class and lab are “No Cell Phone Areas” so please refrain from using them. Class and lab decorum requires that you act socially professional, treat fellow students with respect, and appreciate their viewpoints and beliefs. # 2: Mar. 16 Percent contribution to final grade #3: April 11 60 20 20 Final: May 2 (Wed): 12:30 PM - 2:30 PM Other Important Items Important Dates: Academic Honesty: Jan 16 (Monday) Feb 3 (Friday) Mar 5- 9 (Monday - Friday) April 13 (Friday) April 25 (Wednesday) April 26, 27 (Thursday, Friday) April 28, 30 May 1- 4 M.L.

In 1995 the UF student body enacted an honor code (http://www.dso.ufl.edu/sccr/honorcodes/honorcode.php) and voluntarily committed itself to the highest standards of honesty and integrity. When students enroll at the university, they commit themselves to the standard drafted and enacted by students. Disability Issues: Software Use: Campus Assistance Resources: The Honor Pledge: We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity. On all work submitted for credit by students at the university, the following pledge is either required or implied: "On my honor, I have neither given nor received unauthorized aid in doing this assignment." Students should report any condition that facilitates dishonesty to the instructor, department chair, college dean, Student Honor Council, or Student Conduct and Conflict Resolution in the Dean of Students Office. It is assumed all work will be completed independently unless the assignment is defined as a group project, in writing by the instructor. This policy will be vigorously upheld at all times in this course. Students should report any condition that facilitates dishonesty to the instructor, department chair, college dean or Student Honor Court.

Please refer to the lab schedule to determine where lab will be each week. A map and (or) directions can be found at the end of this syllabus and the course web page. 1) To provide “hands- on’ experience in dissecting and describing the gross anatomy of the hypothalamic/pituitary and reproductive systems of male and female farm animals. 2) To develop limited skills and understanding of the basic principles of collection, evaluation, extension, and freezing of semen from farm animals. 3) To introduce the concept of early embryonic development and provide hands- on experience dissecting pregnant reproductive tracts from the bovine and porcine. 4) To develop limited skills and understanding of estrous synchronization, artificial insemination, embryo collection, embryo freezing, reproductive ultrasonography, and pregnancy diagnosis in the bovine, porcine, and equine species. Grading: Activities: Lab Policies: Lab is worth 20% of your final course grade. Each lab is worth 50 points, which is based on attendance (25 pts) and weekly take- home message (25 pts), which are handed in at the start of each lab. You have to be physically present to receive credit for lab and hand in the take- home message to receive credit for it. There will be a mid- term practicum and a final lab exam worth 200 points each. Your low lab grade during the semester, excluding the lab practicum and final exam, will be dropped from your final lab grade. If you have 3 or more unexcused lab absences (after the drop) you will receive an “E” for the course. The primary objectives of lab are to provide hands- on activities with live animals, dissection of tissues harvested from deceased animals, and operating laboratory and technical equipment frequently used in reproductive biology. Throughout the semester, you will work with live cattle, pigs, and horses. Although domesticated, these animals are not “tame” like pets and they must be handled accordingly. All farm animals can be dangerous and cause injury to either themselves and (or) people if handled incorrectly. Although horses are typically gentle, they too can be dangerous to the uninitiated. Therefore, it is our responsibility to provide a safe teaching environment for livestock and students by using different restraining devices commonly used in animal production. Lab activities will also include dissection of tissues including the cow and sheep brain, female and male reproductive tracts, and other tissues obtained from the abattoir. You will be required to dissect and study these tissues in lab. The utilization of live animals and dissection of tissues are central to effective learning and enhancement of your lab experience. For whatever reason(s) you feel you are unable to work with live animals and animal tissue used for dissection, and (or) participate in any lab activities you need to contact Dr. Yelich at the start of the semester to discuss these issues. There will be no make- up labs during the semester. Any lab missed for reasons other than those listed below will not be excused and a grade of “0” will be recorded for the both lab and take- home message. You have to attend lab and hand- in your take home message in order to receive full credit for lab. All requests to be excused from a lab must be submitted to Dr. Yelich either in writing or requested by email. This policy will be strictly enforced. Excused absences include: 1) Absence for a university- approved field trip or activity (must be cleared one week in advance). 2) Absence for a death (verification by obituary if requested) or serious illness in family. 3) Absence resulting from personal illness (verification consisting of a letter of explanation from hospital or doctor on official letterhead). Please review the excuse note policy of the Student Health Care Center (http://shcc.ufl.edu/forms- records/excuse- notes/). If you need to attend another lab other than your scheduled lab, please contact Dr. Yelich either in person, or by phone/email to request a change of lab and the reason for the change. Failure to do so will result in a “0” grade for that lab. Request to re- grade a take- home message must be made within one week from the date the take- home message is returned in lab. Grade challenges must be submitted in writing, attached to the exam, and returned to the lab instructor.

From Gainesville, drive north on US 441 towards Alachua. 2. The turnoff for the Dairy Unit is County Road 237. A sign that says Hague also marks this road. It is approximately 6 miles from the Highway Patrol Station at the corner of US 441 and SR121 (34th St.) to CR237. Make a right at CR237. If you end up in Alachua, you have gone to far so make a U- turn!!! 3. After turning on CR237, you will immediately come to the town of Hague. Drive through Hague, cross the railroad tracks and go about 1/2 mile. The Dairy Unit will be on the right. There will be a UF sign identifying the Dairy Unit at the entrance. Turn right. 4. Proceed down the long drive to the main building, which is at the end of the drive. At this point, the drive forms a circle in front of the main building and there is a sign with a painting of a Holstein in the center of the circle. You are there. Park your car in the parking lot on the left. You can wait for the start of class either outside the building directly behind the sign with the Holstein cow on it or in the classroom located inside the building. ...
