The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. [1] Both are genetically important, as each parent genes can be existent with a 50% probability in the foal.
When a mare is pregnant, she is said to be "in foal". When the mare gives birth, she is "foaling", and the impending birth is usually stated as "to foal". A newborn horse is "foaled". After a horse is one year old, it is no longer a foal, and is a "yearling". There are no special age-related terms for young horses older than yearlings.
Mare reproductive loss syndrome (MRLS) is a syndrome consisting of equine abortions and three related nonreproductive syndromes which occur in horses of all breeds, sexes, and ages. MRLS was first observed in the U.S. state of Kentucky in a three-week period around May 5, 2001, when about 20–30% of Kentucky's pregnant mares suffered abortions ...
A broodmare. Note slight distension of belly, indicating either early pregnancy or recent foaling. A mare is an adult female horse or other equine. [1] In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger.
When not erect, the penis is housed within the prepuce, 50 cm (20 in) long and 2.5 to 6 cm (0.98 to 2.36 in) in diameter with the distal end 15 to 20 cm (5.9 to 7.9 in) free in the prepuce. The retractor muscle contracts to retract the penis into the sheath and relaxes to allow the penis to extend from the sheath.
In fact, a study in The Journal of Sexual Medicine found that nipple stimulation is arousing for 52% of men—yet only 17% of men have had their nipples played with during sex. Clearly, there’s ...
Male reindeer grow antlers as long as 50 inches after multiple seasons of shedding. Females grow 20-inch antlers. Females shed their antlers in May, just after their calves are born but they begin ...
The researchers studied 46 such parabiotic pairs. In over half of the pairs, neither the male nor female became pregnant with normal embryos; in about one-third of the pairs, only the female became thus pregnant; and in six pairs, both the female and male became pregnant. There were no pairs in which only the male parabiont rat became pregnant. [7]
