Abstract
This paper will deal primarily with the evaluation of various methods to control the estrous cycle in cattle. Consideration will be given to four methods of altering the normal estrual cycle. (A) The inhibition of ovulation as a means of altering the estrual cycle appears to be receiving most attention in recent years. The bulk of this paper will deal with ovulation inhibition by progestogens; thus, it would seem appropriate to give a brief evaluation of the other three methods.
