COURSE DESCRIPTION

A hands-on study of the practical aspects of reproduction in cattle. Students will apply their knowledge of reproductive anatomy and physiology in hands-on field and laboratory exercises.

COURSE OBJECTIVES

The objectives of this course are to familiarize students with a broad view of reproductive physiology and anatomy of cows and bulls, as well as the technical aspects of cattle breeding and artificial insemination.

PREREQUISITES

AGSC 352: Animal Reproduction

TEXTBOOK

Mitchell, J.R., G.A. Doak, and J.A. Smith. 2004. The Artificial Insemination and Embryo Transfer of Dairy and Beef Cattle. Prentice Hall.

COURSE OUTLINE

Students will learn about:

• The Cow
  1. reproductive anatomy
  2. endocrinology and the estrous cycle
  3. pregnancy events/palpation
  4. increasing ovulation rate and embryo harvest
  5. parturition and obstetrics
  6. lactation and rebreeding concerns
• The Bull
  1. reproductive anatomy and physiology
  2. principles of semen collection and artificial insemination
• The Calf
  1. factors affecting dystocia
  2. orphan management

CALVING AND BREEDING

To the extent that is possible, each student is expected to observe the cow herd for signs of the onset of parturition and participate in normal and assisted parturition practices. Students will be guided through attempts to artificially inseminate selected cows postpartum.
