Estrus Synchronization in the Sheep and Goat.
The Veterinary clinics of North America. Food animal practice, 2021Estrus synchronization and manipulation are a tool that has been used by producers to provide uniform lamb and kid meat production and dairy sheep and goat milk production, to concentrate work and labor cost, and to plan for the lambing and kidding time.

Three experiments evaluated the effects of expression of estrus and gonadotropin releasing hormone (GnRH) treatment on pregnancies per AI (P/AI) in beef cattle that were treated with an estradiol/progesterone (P4)-based protocol for fixed-time artificial

Abstract One dictionary de0nition of estrus is “the periodic state of sexual excitement in the female of most mammals, excluding humans, that immediately precedes ovulation and during which the female is most receptive to mating” (American Heritage Dictionary of the English Language).

The objectives of the present study were to assess the effect of permanent contact of teasers without copulation on the interval from controlled internal drug release (CIDR) removal to estrus onset, estrus duration, ovulation time, number of ovulations, and interval from CIDR removal to ovulation time on estrus-synchronized Boer goats.

Abstract As we noted in our introductory chapter, over four decades ago researchers offered a de0nitive conclusion about women’s sexuality: Over the course of the last several mil- lion years, women had lost estrous sexuality. Modern women possess no distinct fertile sexuality within their cycles. The theoretical perspective we presented

There are three distinct substances in the human placenta that are capable of producing estrus precociously when administered to immature rats or mice; the first is ether soluble, the second ether insoluble but alcohol soluble, the third alcohol insoluble.

Estrus detection and estrus characteristics in housed and pastured Holstein–Friesian cows
Theriogenology, 2010This study compared three methods of estrus detection and characteristics of standing estrus between dairy cows kept in cubicle housing and fed a total mixed ration diet (HOUSED treatment) and those kept at pasture with concentrate ration supplementation (PASTURE treatment).
