Estrus Synchronization in the Sheep and Goat
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.

Since 1952, scientists have studied estrus suppression in dogs. Estrus suppression in dogs must be safe and reliable. Medications used for estrus suppression in bitches include gonadotropin-releasing hormone (GnRH) agonists, GnRH antagonists, progestogens, and androgens.

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

During fall season, 18 multiparous Corriedale ewes were divided into two equal groups for the continuous (CON) and intermittent (INT) presence of a ram. Estrus was synchronized with fluorgestone acetate intravaginal sponges that were left 14 days, plus an injection of 200&mgr;g of a prostaglandin F-2alpha analog at sponge removal.

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.

Control of Estrus in Gilts with a Progestogen
Journal of Animal Science, 1979Two trials were conducted to evaluate the effectiveness of a synthetic progestogen, allyl trenbolone, for control of estrus and ovulation in gilts. Estrus was effectively synchronized with 33 of 38 gilts exhibiting estrus 2 to 7 days after last progestogen feeding.

Time of onset of estrus in gilts
Theriogenology, 1986An experiment was conducted to determine when, during a 24-h period, gilts show the onset of behavioral estrus. Beginning on Day 16 of their first estrous cycle, 42 crossbred gilts were observed at 0600, 1200, 1800, and 2400 h for the onset of their second estrus. Fifty-five percent of the gilts had shown onset of estrus by 0600 h.

Chemical inhibition of estrus in the beagle
Theriogenology, 1976Abstract Twenty anestrus bitches were dosed orally for 90 days with vehicle or 0.9 mg/kg b.w. of 6,6-spiroethylene-19-nor-spiroxenone. All dogs were due in estrus during the test period based on previous average estrous cycle lengths. Estrus was prevented in 100% of the drug-treated bitches.
