Method for breeding control in female bovines
First Claim
Patent Images
1. A method for fertile breeding control in female bovines comprising:
- (a) establishing an estrus and ovulation blocking period of several days by continuous administrating of a progestin using an implant which slowly releases the progestin into the blood stream;
(b) injecting a luteolytic agent while continuing the administration of the progestin for a period of 1 to 6 days; and
(c) terminating the administration of the progestin, thereby allowing estrus and ovulation to occur in a shorter time period and in a relatively narrower time span than if administration of the progestin was terminated at the time of injection of the luteolytic agent.

Abstract
A method for reducing the time to estrus onset and duration of estrus in female bovines, is described. The method involves a sustained low level release of progestin over time with injection of a luteolytic agent, particularly a prostaglandin, towards the end of the time such that there is an overlap of progestin and prostaglandin administration. The sustained release is preferably by means of a vaginal implant. The method is faster and easier to use than prior art methods.
