Problems solved by technology

Although CIDR ? Advocates assert much better results, but many CIDR ? It is not uncommon for protocols to experience conception rates as low as 20%, and even lower for virgin heifers
In addition, high infection and vaginitis rates, and concomitant CIDR ? Discomfort and stress to animals, fairly common, detracts from results

Embodiment Construction

[0035] The teachings of the present invention are preferably embodied in injectable hormonal formulations and regimens using such hormonal formulations to improve estrus synchronization and achieve higher rates of estrus synchronization and maintenance of the desired larger corpus luteum size. Those skilled in the art will appreciate that other techniques known to optimize the benefits of estrus synchrony further facilitate the regimens and formulations administered below in connection with the present invention. Such other techniques include maintaining adequate nutrition for cows and heifers and striving to maintain adequate overall body scores. Those skilled in the art will also recognize that alternative applications of the compounds and regimens of the invention may include preparing recipient cows for embryo implantation.

[0036] With reference to various aspects of the preferred embodiment of the present invention, the applicant has developed what the applicant wishes ...

Abstract

An injectable preparation of estrogenic and progestrogenic hormonal compounds in an anhydrous excipient injected to synchronize estrus in non-menstruating placental female animals, and a five to nine day protocol to apply the unique preparation to achieve estrus synchronization.

Description

[0001] [0002] CROSS-REFERENCE AND PRIORITY STATEMENT TO PROVISIONAL APPLICATIONS [0003] This application claims priority under 35 U.S.C A § 119(e) to U.S. Provisional Application 61 / 206077, filed January 26, 2009, entitled "Eestrus Synchronization Compounds and Regimen." The entirety of this provisional application is incorporated into this application by reference. technical field [0004] A. technical field [0005] The present invention generally relates to the field of artificial insemination and embryo transfer of estrous animals, and more particularly, the present invention relates to protocols and drugs for promoting, managing and controlling estrus synchronization in such animals. Background technique [0006] B. Estrus Synchronization [0007] In animal reproduction, "estrous synchronization" generally refers to the artificial synchronization of estrous cycles across a herd of females using hormone treatments and adjunctive regimens. Such animals may inclu...
