Synchronization of estrus (heat) involves manipulating the estrous cycle of beef females so they can be bred at approximately the same time. There are several protocols available for synchronizing estrus among beef females. Traditional protocols are designed to mimic or control the corpus luteum on the ovary. New protocols have been designed to control ovulation and/or the follicular waves that occur on the ovary during the 21-day estrous cycle. There are three primary groups of products used to synchronize estrus or ovulation in beef cattle: prostaglandins, progestins, and gonadotropins. Prostaglandin products have the trade names of Lutalyse, Estrumate, and IN-SYNCH and each contain prostaglandin F2? (PGF2?) or an analogue of PGF2?. The progestin products include the vaginal implant CIDR® and Melengestrol Acetate (MGA), that is consumed orally. The GnRH products are Cystrorelin, Factrel, and Fertagyl.

Chocolate milk made from menstral cows?
Only in your dreams. Chocolate milk is not made from cows: white milk is, at least the most common term "milk" derives from the definition of "cows milk." Plus, "menstrual" cows (use of anthropomorphication here) do not produce milk of any kind. Cows in estrus, not menstrual, or in heat, are lactating, yes, but only because they gave birth to a calf a couple months ago. Young cows or heifers that are in heat do not produce milk because they have not had a calf.The common misconception that "chocolate" in milk is from cow's blood is absolutely false and completely ridiculous. Chocolate comes from cocoa beans, and to make chocolate milk lots of sugar in the form of corn syrup or other sugary additives are added to the milk along with cocoa from the cocoa beans.Lastly, menstrual cycles only occur in primates. Cows do not have menstrual cycles, they have estrus and estrous cycles, a much different cycling of the female reproductive cycle.

Will a cow cycle in the winter?
Yes, cows can cycle in the winter, but their reproductive activity may be affected by factors like temperature and daylight hours. Cows are seasonal breeders, and their estrous cycles can be influenced by environmental conditions. While some may experience heat cycles during colder months, overall reproductive efficiency might decline due to stressors associated with winter conditions.
