Abstract

In cattle the uterus determines the lifespan of the corpus luteum. Hysterectomy (8) prolonged the life of the corpus luteum while uterine distention from balloons (3) and plastic coils (1) and irritation from contaminated seminal fluid (3), a viral agent (4), and iodine solutions (5,6,9) all shortened the estrous cycle.

These substances in the uterus activate a uterine luteolytic mechanism. An understanding of uterine luteolytic mechanisms may permit the development of both satisfactory estrous synchronization techniques arid contraceptive procedures. The objective of this study was to determine the effects of intrauterine infusions at various stages of the estrous cycle on estrous cycle length, estrous behavior, ovarian activity, and levels of luteinizing hormone (LH) in peripheral plasma of cattle.
