REPRODUCTIVE PHYSIOLOGY & ENDOCRINOLOGY IN DOMESTIC ANIMALS

Objectives: 1] To familiarize students with the general aspects of reproductive physiology & endocrinology of the male and female of domesticated animals.

2] Identify & discuss the interrelationships between the hormones produced by the reproductive glands & their target organs of the male & female.

3] Describe similarities & differences in reproductive functions between domesticated animals that include the bovine, ovine, porcine, equine & avian species.

4] Discuss sound reproductive management programs that will maximize breeding efficiency of domesticated animals.

Textbook: Pathways to Pregnancy and Parturition, 2^nd Edition 2003, P.L. Senger, Current Conception Inc., Pullman, WA. This is an excellent text required for Lecture & Lab.
