A mare may be in heat for 4 to 10 days, followed by approximately 14 days in diestrus. Thus, a cycle may be short, totaling approximately 3 weeks. [21] Horses mate in spring and summer; autumn is a transition time, and anestrus occurs during winter.
The estrous cycle (also spelled oestrous) controls when a mare is sexually receptive toward a stallion, and helps to physically prepare the mare for conception. It generally occurs during the spring and summer months, although some mares may be sexually receptive into the late fall, and is controlled by the photoperiod (length of the day), the ...

The Hoover-Drickamer effect was initially demonstrated in J.E. Hoover and L.C. Drickamer's 1979 study. The researchers noted that while other studies had examined the effect of urine from pregnant and/or lactating females on the onset of puberty in young female mice, no work had been done to examine what urine from pregnant and/or lactating females would do to oestrous cycles in already ...
If the mare was prevented from doing so, she would feel no affection for the foal and refuse to feed it, which is why it was believed that the power of love was concentrated in the hippomanes. The vulval discharge from the mare in oestrus was also referred to as Hippomanes in antiquity and was used equally for love potions and love spells. [8] [9]
This period of advertised fertility is known as oestrus, "estrus" or heat. [9] In species that experience estrus, females are generally only receptive to copulation while they are in heat [9] (dolphins are an exception). [10] In the estrous cycles of most placentals, if no fertilization
This is normal and does not impact the effectiveness of the device or the animal’s performance. [3] There are several types of CIDRs available, including CIDR-B for cattle, CIDR-S for sheep and CIDR-G for goats. CIDRs are similar to the progesterone-releasing intravaginal device (PRID), also used for synchronization of estrous cycles in ...
