The instructor can be contacted via email to ask a question or schedule a meeting. Responses generally occur with 24 - 48 hours depending on the presence of the instructor on campus. Email is only examined M-F during work hours. Alternatively you may stop by his office for an unscheduled meeting if he is in and available. There are no scheduled office hours but every effort will be made to meet with students as needed.

Graduate Credit for the Course

This course is available for graduate credit. According to University Policy, an additional project is required by graduate students if they wish to receive graduate credit for this course. Please see Dr. Parrish for further information.


In 2017, all lectures will be delivered live. While Podcasts of previous years lectures will be available on-line, it is not guaranteed to represent what is given in 2017. Many previous years are available for continuity and those using the course material at another US or International institutions.


This will not occur in 2017.


Section 301: 12:00 p.m. - 2:00 p.m. Tuesday (128 Animal Science)
Section 303: 12:00 p.m. - 2:00 p.m. Wednesday (128 Animal Science)
Section 304: 3:30 p.m. - 5:30 p.m. Wednesday (128 Animal Science)

You are assigned to a group of 3 or 4 students within a lab section. These lab groups change from week to week. You are assigned to a particular group randomly. Lab write-ups are due from specific groups the next week following the active lab. Therefore, you must attend your lab section only!!! Attending another lab sections will not allow you to have access to hands-on-material or animals. For lab absences, see bottom of this page.

The lab material was written and designed by Dr. Parrish and is mostly available on-line. We do have at least 1 Instructor/TA present in every lab and Dr. Parrish will be present in most lab periods. The Instructor/TA are:

Lab Instructor - Rick Monson <>, 758 Animal Science, 263-4322
Teaching Assistant - Nicole Gross <>, 532 Animal Science.

Cow Project

You are assigned a cow to manage during the semester as a part of a group. See the specific description and deadlines for the project.

Lab Project

Reproduction in Mexico or aspects of Hispanic labor in the beef industry. You will create some type of solution to a specific case related to the topic. You may choose to do as in years past as a website but this year we will allow you to use your creative talents and do anything. For example this could be a video, audio story, or written paper. Keep in mind that this will be a group project and so we are expecting each person to put in the equivalent of work it would take to write a 15 - 20 page paper. A public service announcement as an oral podcast is the audio requirement for the case and is different that what you might do in the main solution you choose to implement.


Pathways to Pregnancy and Parturition, P.L. Senger, 3rd revised edition. While you may use older versions, you will be held to the new version for exams.

Lecture exams - given during the lecture period in room 212 (check to confirm this for current year). See specific dates listed below in the schedule. We stick to these dates and times, so therefore we expect you to as well. You must contact Dr. Parrish if you must miss an exam or you become sick. He will discuss with you when or if a make-up exam will be given.

Oral exam - This occurs during weeks 13 - 16 and time slots will be open for you to sign-up for this as the time approaches. See an explanation of the exam below the tentative schedule. This is a comprehensive exam.

Lab exams - New in 2017 - Lab Quizes will be given tuesday each week in lecture (10 points) and cover the lab from the previous week. There will be no big lab exams in 2017.

Final exam - Is scheduled at a time and location set by the university. In this course, the final exam material simply covers from exam II to the end of class and is not comprehensive.

Lec Exam III -- Dec 21, 2017-- Thur. -- 12:25 - 2:25 PM
(Time Assigned by University and out of Instructor's Control !!!!)

Exam Questions - The lecture exam questions can be of any form but in the past have been 40% of a multiple-multiple choice format, 40 % are true:false, 10% matching, and 10% as short answer or essay. Practice, on-line, exam questions are included at the end of each lecture outline. Old exams using the current exam format are not provided. Exams are not returned to students after the exam. Students can review their exam results in their respective lab and only in the presence of the instructor. You may make an appointment to review your exam in Dr. Parrish's office if you wish to examine your exam further or challenge the scoring of your exam.

Grading - The tentative grade structure in the course will be determined on the basis of:

1st lecture Exam 100
2nd Lecture Exam 100
3rd Lecture Exam (given during final exam period) 104
15 lab quizes given in tuesday lectures 150
Lab Project 80 points written, 30 points audio) 110
Lab Project Questions (appear on exam during final exam period) 20
Cow Project 50
Oral Exam  (comprehensive) 80
Lab Exercises (13, each 5 points) 65
Lab presentations (10 points each) 30
Total Points 809
Changes to these grade items, additional or fewer items and points allocated are at the discretion of the instructor.  

Oral Exam. We will have a set of questions and randomly assign students to answer 1 of the questions. You will have 10 minutes to prepare your response. You will then record an oral only podcast of your answer that does not exceed 10 minutes in length. An instructor or TA will help you save your recording for grading by the instructor. Sign-up for the exam will begin Nov. 1 and the exam may be taken between weeks 13 - 15. You may think of this exam as an extended essay question recorded in a different format. All lectures 1 - 26 are covered by this exam so you should complete all lectures before taking this exam. A set of key concepts for the class are available in the Learn@UW site and under content.

Final Grade. This will be assigned based on a percentage of the total possible points available. Grades are recorded simply as a score on a project, exam or lab exercise and then totaled at the end and expressed as a percentage of total available points. The final grade assignments will be made according to the following distribution:

A (100-93%), AB (88-92.99%), B (83-87.99%), BC (75-82.99%), C (65-74.99%), D (55-64.99%), F (<55%).

Note again that this is based on total points so when the bottom A is 93%, that is (0.93 * 809) or 752.37 points, 752 points is 92.95% and thus an AB. It is important to note that there is no rounding used in assigning the final grade. Changes to the grade ranges are again at the discretion of the instructor. In general, you will get at least the grade indicated above but the instructor has the option of lowering the standards, thus yeilding you a better final grade. No bonus points are offered in this class.

The average score in 2016 on exam 1 was 73%, on exam 2 was 77.3%, on exam 3 was 86.6%, on the oral exam was 94%, on lab exam 1 was 77.9%, on lab exam 2 was 87.4% and the project score average was 94%. The average grade was at the top of the B range.

The average score in 2015 on exam 1 was 73.8%, on exam 2 was 78.6%, on exam 3 was 87.2%, on the oral exam was 93.1%, on lab exam 1 was 84.5%, on lab exam 2 was 83.5% and the project score average was 94.6%. The average overall or final scores in 2008-2015 were 85.67, 86, 85.69%, 88.65%, 88.48%, 88.40%, 88.61% and 88.1% respectively. Thus the average grade in 2011-2015 is the bottom of the AB range. In 2008-2010 the average grade was a B. For 2014 if you take the average exam scores only and calculate the final grade without imput of projects and lab activities, the final score would be 83.25% or the bottom of the B range. The other activities in class thus are essential in raising you final class grade.

In case you miss lab - Much of the material in this class can be completed on-line if you are prevented from attending class. You will however miss out on any hands-on lab exercises or discussion that go on in the lab sections. In general, we have full lab sections and you can not just attend another lab without prior instructor approval. If you miss your assigned lab for any reason, you will be required to complete a lab writeup on your own and submit a paper copy to your original lab instructor or TA.
