SCIENTIFIC FARM ANIMAL PRODUCTION by T. G. Field and R.E. Taylor, 11th Edition, 2016 Prentice-Hall, Inc., Upper Saddle River, NJ To introduce students to the broad field of animal science and to develop an appreciation of the importance of the livestock and meats industry in American agriculture and to the American economy. The student should become acquainted with the basic principles of livestock production through discussions of animal anatomy, genetics and breeding, physiology, lactation, growth and body composition, nutrition, and meat science. By the end of the course, students should: 1. be familiar with livestock terminology, the expected performance of animals raised using good management and husbandry practices, and characteristics of the primary breeds of farm livestock. 2. understand principles underlying the selection of replacement stock for continued genetic improvement in the herd or flock. 3. understand animal reproduction, some management principles for improving reproductive efficiency, and be familiar with technologies such as estrous synchronization, artificial insemination and embryo transfer. 4. understand how milk is synthesized, stored and released during milking or nursing. 5. understand changes in body composition relative to muscle, fat, and bone as an animal grows and understand how these changes affect gains, feed efficiency, market grades, and market price. 6. know the major components of livestock feeds and be able to compare similarities and differences in feed digestion by cattle, sheep, swine, and horses.

2 Grading: The final grade in the course will be based on your accumulated percentage of the total points possible according to the following distribution: Lecture Points Percent of grade 2 hour exams Weekly quizzes Comprehensive exams % Lecture points A = 90% or above 540 or more B = 80 89% C = 70 79% D = 60 69% F = less than 60% fewer than 360 Quizzes: Lecture Exams: A minute quiz will be given on Fridays (unless previous changes are announced). The quizzes will predominately cover lecture material since the most recent quiz or hour exam. There may periodically be pop-quizzes as well. No make-up quizzes will be given. The exams will be given on the following dates: 1 st hour exam Friday, September 8 Midterm exam Friday, October 13 2 nd hour exam Friday, November 3 Final exam Monday, December 8:00 a.m. No one will be permitted into the exam late after the first person has completed their exam!!! Make-up Exams: Spelling: Final Exam: Attendance Policy: Cell Phone Use: A make-up exam will be given only for pre-approved excuses or extremely extenuating circumstances. The exam will be comprehensive and will be given at the end of the semester. Arrangements to take the make-up exam must be made in advance. Students who miss an exam because of illness need a doctor's statement for verification of sickness and should clear the absence with the instructor the day they return to class. Other unavoidable absences from the campus (field trips, intercollegiate events, etc.) must be documented and cleared with the instructor in advance. All livestock terms including breeds must be spelled correctly on exams and weekly quizzes. One-half point will be deducted for each misspelled term. Livestock breeds must be capitalized. Scheduled for Monday, December 4 at 8:00 a.m. Students are expected to attend all scheduled classes. It is the responsibility of the student to initiate arrangements for missed work due to excused absences. (See above statement for make-up exams.) The instructor may give unannounced quizzes during any lecture for the purpose of determining class attendance. In accordance with Academic Operating Policy the use by students of cell phones, messaging devices, and other electronic devices is prohibited. Cell phones will be turned off during class, or on silent (NOT vibrate) mode and stow in personal packs while attending class. On quizzes and exams cell phones may not be used as calculators or clocks. A copy of AOP is available online at

3 Honesty: Mississippi State University has an approved Honor Code that applies to all students. The code is as follows: "As a Mississippi State University student I will conduct myself with honor and integrity at all times. I will not lie, cheat, or steal, nor will I accept the actions of those who do." Upon accepting admission to Mississippi State University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning, and to follow the philosophy and rules of the Honor Code. Students will be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the MSU community from the requirements or the processes of the Honor Code. For additional information please visit: Lecture Notes: Copy of material used in lecture and lab will be made available on the Web at the following URL: bjr13.ads.msstate.edu Title IX: MSU is committed to complying with Title IX, a federal law that prohibits discrimination, including violence and harassment, based on sex. This means that MSU s educational programs and activities must be free from sex discrimination, sexual harassment, and other forms of sexual misconduct. If you or someone you know has experienced sex discrimination, sexual violence and/or harassment by any member of the University community, you are encouraged to report the conduct to MSU s Direction of Title IX/EEO Programs at or by to titleix@msstate.edu. Additional resources are available at or at Support Services: Students who need academic accommodations based on a disability should visit the Office of Student Support Services, 01 Montgomery Hall, call , or visit the website at This syllabus was written with the intent of conducting the course as outlined. However, in the event of extenuating circumstances the instructor reserves the right to make changes.
