Time & Place:	1-1:50 Mon. and Wed., Ag. 152
				
Course Learning Objectives:

1.	Understand the comparative anatomy of the mammary gland.

2.	Understand the endocrinology of reproduction.

3.	Understand the physiological mechanism of mammogenesis, lactogenesis, galactopoesis, 
	milk ejection, and involution.

4.	Understand the composition of milk and factors that effect composition and yield.

5.	Understand the secretion and synthesis of milk components.

6.	Understand lactation-related disorders and diseases.

7.	Understand the production and potential importance of transgenic milk.

Grading:	

Quizzes and Exams: Six quizzes and two midterms will be given.  
The lowest quiz will be dropped.  Quizzes can not be made up.  
A missed quiz will be counted as your dropped quiz.  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 
the  instructor before the regularly scheduled exam.  The Final will be Tuesday, 
December 12, 12:50-2:50 PM (75% comprehensive).

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 dealing with lactation in any scientific journal 
from 2000 to present.  The summaries should not exceed 2 pages and 
should include the journal reference, introduction, methods, results, 
and discussion.  Do not plagiarize!  Extra credit opportunities will 
also show up occasionally on the course webpage.  Additional, extra 
credit opportunities may also arise during the course.  Extra credit 
is often given for attendance when the majority of the class is absent.

Species Term Paper: A term paper will be written on the lactation 
of the dog, cat or another mammalian species other than cow, horse, 
pig, sheep, goat, or human. The term papers should be between 2 and 5 pages 
and include (at a minimum) information on the following areas (as subheadings): 
Mammary Gland Anatomy, Physiology of Mammogenesis and Lactation, Milk Composition, 
and Neonatal (Nursing) behavior. Species Term papers will be due on Nov. 27.

Milking Experience: Each student will be required to observe and participate 
in a milking at the SIU Dairy Center. Make appointments with 
Chet Stuemke (hoofguy@siu.edu), the SIU Dairy Manager. Chet would prefer students 
to milk at the 6 AM milking M-F, but will make special arrangements for the 5 PM milkings. 
Students will be required to fill out a form signed by Chet 
or the milker on duty in his absence.

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.

The instructor reserve the right to lower the curve as appropriate.   
The curve will not be raised.    The instructor realizes that 
the mixture of undergraduates and graduates in the  course suggests 
different levels of preparation.  This will be considered at the time 
of grading.
