Course Learning Objectives:

1.	Know the general anatomy & histology of the male and female 
	reproductive systems.
2.	Understand the endocrinology of the estrous cycle, pregnancy, 
	& lactation.
3.	Know the length of the estrous cycle, estrus, and gestation 
	in farm animals
4.	What are the functions of the cells of the ovary and testis.
5.	Understand the basics of oocyte and spermatozoa maturation.
6.	Understand how the gametes are transported through the male 
	and female reproductive systems.
7.	Know the steps involved in fertilization.
8.	Understand the basic events of embryo and fetal development.
8.	Understand the basics of maternal recognition of pregnancy, 
	implantation, & placentation.
9.	Understand the events of parturition.
10.	What are the events of courtship and mating in farm animals.
11.	What are the general causes and examples of reproductive failure 
	in farm animals.
12.	Understand the reproductive peculiarities and the reproductive 
	management of cattle, sheep, horses, swine, and poultry.
13.	Understand the basics of reproductive-assisted biotechnologies 
	including AI, estrus synchronization, superovulation, embryo 
	transfer, transgenics, IVF, sperm and embryo sexing, embryo 
	splitting, nuclear fusion, and reproductive immunization.

Grading:	

Quizzes: Twelve quizzes will be given during the first 10 minutes of each 
Friday lecture of non-exam weeks covering material from the lectures and 
labs from the previous week since the last quiz.  The lowest two quizzes 
will be dropped.  Quizzes can not be made up.  A missed quiz will be counted 
as the dropped quiz.

Exams: Three Mid-terms (Exam 1, Exam 2, Exam 3) and a Final Exam will be 
given in the course.  Make-up exams will be essay or oral at the instructors'
discretion.  20% will be taken off the top of any make-ups given to students
who do not notify an instructor before the regularly scheduled exam.  
The Final is 50% comprehensive.The final will only be given at the scheduled time-no 
make-ups or early exams. Students that do not take the final will be given "0" 
on the final or an incomplete depending on the circumstances determined by the instructor.

Laboratory: Attendance is mandatory in laboratories.  Dr. Jones is the Laboratory instructor. 
Lab coats for labs in Ag. 114, and barn clothes for labs at the farms are strongly recommended.

Extra Credit: Midterm exam grades can be increased by up to 5 points each by 
turning in a scientific paper summary within 1 week of the day that exams 
are returned.  Summaries are to be obtained from a scientific paper published
in 2007 or 2008 from the journals Biology of Reproduction, Theriogenology, 
Domestic Animal Reproduction or Journal of Reproduction and Fertility.  
The summaries should not exceed 2 pages and should include the journal reference, 
introduction, methods, results, and discussion (as subheadings).  Do not plagiarize!  
Extra credit opportunities will also show up occasionally on the course webpage.  
Extra credit will also be given for certain reproductive physiology related seminars 
or related events on campus.  All extra credit will be added to midterm exam scores

Incompletes: Incompletes will only be given in special cases with written 
endorsement from a medical professional or university official.  Failing 
the course is not a reason for receiving an incomplete on its own.    
Special arrangements can be made for students called up for Military duty.

Grading Breakdown:	 25% 	Laboratory		A=90 to 100%
			 15% 	Quizzes			B=80 to 89%
			 40% 	3 Midterm Exams		C=70 to 79%
			 20%	Final Exam		D=60 to 69%
			100%	Total			F=<60%	

The instructors reserve the right to lower the curve as appropriate.  
The curve will not be raised.  Graduate students will be not be included in 
the undergraduate student curve.
