- ASCI 330 (Animal Breeding), or its equivalent, is the prerequisites for this course. Please do not enroll in ASCI 431/831 until you have successfully completed that prerequisite course.

- Demonstrate an understanding of the state-of-the-art applications of animal breeding and quantitative genetics (including their benefits and limitations) to the genetic improvement of livestock within the United States and elsewhere in the world.
- Demonstrate an ability to locate and interpret research results, and recognize the applications of such research to livestock breeding programs.
- Demonstrate an understanding of sources of variation in performance of animals, and the methods used to control or adjust for this variation.
- Predict responses to selection for a broad array of selection situations, including the use of molecular markers.
- Predict average performance of crossbred populations and mean industry values for breeding systems using crosses of several different breeds.
- Plan future breeding program strategies contingent upon the goals that are established.
