[8]. strepera ) has an orange-lined bill, white belly, black and white speculum that is seen as a white square on the wings in flight, and is a smaller bird. [22]. Animals Mating Mare Horse - Animal Mating Live Prostaglandin: secreted by the endrometrium days following ovulation, causes luteolysis and prevents the corpus luteum from secreting progesterone. How sweet male animals try to seduce a female - not like guys "Hey babe - what's up?". Mares can be used for riding or driving during most of their pregnancy. Exercise is

2 healthy, though should be moderated when a mare is heavily in foal. [. It may be related to, or at least influenced by, an Old High German masculine proper name. Nagin Dhun - Nashik Dhol Mix By Janny Dholi. The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian. Mares are dewormed a few weeks prior to foaling, as the mare is the primary source of parasites for the foal. [11]. Two months after hatching, the fledgling period has ended, and the duckling is now a juvenile. [29]. More similar to the female mallard in North America are the American black duck ( A. Masle (male) has also been proposed as an influence. [10]. Cat Can't Have Enough Of The Fresh Milk. A noisy species, the female has the deep quack stereotypically associated with ducks. [22]. Its legs and bill are also black. [28]. The mallard is omnivorous and very flexible in its choice of food. [58]. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds, [39]. He gave it two binomial names: Anas platyrhynchos and Anas boschas. [3]. The genome of Anas platyrhynchos was sequenced in [6].

3 However, the term is often used more loosely, describing horses with duplication of ancestors closer than the fourth generation. It also is sometimes used as a euphemism for the practice of inbreeding, a practice that is generally frowned upon by horse breeders, though used by some in an attempt to fix certain traits. Changes in hormone levels can have great effects on the physical characteristics of the reproductive organs of the mare, thereby preparing, or preventing, her from conceiving. Similarly, the "breeder", is the person who owned or leased the mare at the time of foaling. That individual may not have had anything to do with the mating of the mare. [1]. The cycle is controlled by several hormones which regulate the estrous cycle, the mare's behavior, and the reproductive system of the mare. The cycle begins when the increased day length causes the pineal gland to reduce the levels of melatonin, thereby allowing the hypothalamus to secrete GnRH. After birth, a foal's navel is dipped in antiseptic to prevent infection, it is sometimes given an enema to help clear the meconium from its digestive tract, and the newborn is monitored to ensure that it stands and nurses without difficulty. Horse breeding is reproduction in horses, and particularly the human-directed

4 process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate of conception, a healthy pregnancy, and successful foaling. built specifically for foaling, especially on the larger stud farms. [16]. Uterus: increased levels of estrogen during estrus cause edema within the uterus, making it feel heavier, and the uterus loses its tone. This edema decreases following ovulation, and the muscular tone increases. High levels of progesterone do not cause edema within the uterus. The uterus becomes flaccid during anestrus. The gestation period lasts for about eleven months, or about 340 days (normal average range days). During the early days of pregnancy, the conceptus is mobile, moving about in the uterus until about day 16 when "fixation" occurs. Shortly after fixation, the embryo proper (so called up to about 35 days) will become visible on trans-rectal ultrasound (about day 21) and a heartbeat should be visible by about day 23. After the formation of the endometrial cups and early placentation is initiated (35 40 days of gestation) the

5 terminology changes, and the embryo is referred to as a fetus. True implantation invasion into the endometrium of any sort does not occur until about day 35 of pregnancy with the formation of the endometrial cups, and true placentation (formation of the placenta) is not initiated until about day and not completed until about 140 days of pregnancy. The fetus sex can be determined by day 70 of the gestation using ultrasound. Halfway through gestation the fetus is the size of between a rabbit and a beagle. The most dramatic fetal development occurs in the last 3 months of pregnancy when 60% of fetal growth occurs. 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 cycle first triggered when the days begin to lengthen. The estrous cycle lasts about days, with the average being 21 days. As the days shorten, the mare returns to a period when she is not sexually receptive, known as anestrus. Anestrus occurring in the majority of, but not all, mares prevents the mare from

6 conceiving in the winter months, as that would result in her foaling during the harshest part of the year, a time when it would be most difficult for the foal to survive. Estrus, or Follicular, phase: 5 7 days in length, when the mare is sexually receptive to a stallion. Estrogen is secreted by the follicle. Ovulation occurs in the final hours of estrus. FSH ( Follicle-stimulating hormone ): secreted by the pituitary, causes the ovarian follicle to develop. Levels of FSH rise slightly at the end of estrus, but have their highest peak about 10 days before the next ovulation. FSH is inhibited by inhibin (see below), at the same time LH and estrogen levels rise, which prevents immature follicles from continuing their growth. Mares may however have multiple FSH waves during a single estrous cycle, and diestrus follicles resulting from a diestrus FSH wave are not uncommon, particularly in the height of the natural breeding season. Thoroughbreds and Arabians are also classified through the "distaff" or direct female line, known as their "family" or "tail female" line, tracing back to their taproot foundation bloodstock or the beginning of their respective stud books. The female line of descent always appears at the bottom of a tabulated pedigree and is therefore often known as the bottom line. [6]. The male

7 parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. Both are genetically important, as each parent provides half of the genetic makeup of the ensuing offspring, called a foal. Contrary to popular misuse, "colt" refers to a young male horse only; "filly" is a young female. Though many horse owners may simply breed a family mare to a local stallion in order to produce a companion animal, most professional breeders use selective breeding to produce individuals of a given phenotype, or breed. Alternatively, a breeder could, using individuals of differing phenotypes, create a new breed with specific characteristics. GnRH ( Gonadotropin releasing hormone ): secreted by the hypothalamus, causes the pituitary to release two gonadotrophins: LH and FSH. Depending on breed, on average, 16% of mares have double ovulations, allowing them to twin, though this does not affect the length of time of estrus or diestrus. Vagina: the portion of the vagina near the cervix becomes engorged with blood right before estrus. The vagina becomes relaxed and secretions increase. [. A horse is "bred" where it is foaled (born). Thus a foal conceived in England but foaled in the United States is regarded as being bred in the

8 US. [1]. Mares due to foal are usually separated from other horses, both for the benefit of the mare and the safety of the soonto-be-delivered foal. In addition, separation allows the mare to be monitored more closely by humans for any problems that may occur while giving birth. In the northern hemisphere a special foaling stall that is large and clutter free is frequently used, particularly by major breeding farms. Originally, this was due in part to a need for protection from the harsh winter climate present when mares foal early in the year, but even in moderate climates, such as Florida, foaling stalls are still common because they allow closer monitoring of mares. Smaller breeders often use a small pen with a large shed for foaling, or they may remove a wall between two box stalls in a small barn to make a large stall. In the milder climates seen in much of the southern hemisphere, most mares foal outside, often in a paddock. Diestrus, or Luteal, phase: days in length, the mare is not sexually receptive to the stallion. The corpus luteum secretes progesterone. Domestic mares receive specific care and nutrition to ensure that they and their foals are healthy. Mares are given vaccinations against diseases such as the Rhinopneumonitis (EHV-1) virus

9 (which can cause abortions) as well as vaccines for other conditions that may occur in a given region of the world. Prefoaling vaccines are recommended 4 6 weeks prior to foaling to maximize the immunoglobulin content of the colostrum in the first milk. [10]. ecg equine chorionic gonadotropin also called PMSG (pregnant mare serum gonadotropin): chorionic gonadotropins secreted if the mare conceives. First secreted by the endometrial cups around the 36th day of gestation, peaking around day 60, and decreasing after about 120 days of gestation. Also help to stimulate the growth of the fetal gonads. Horses with the same sire but different dams are simply said to be "by the same sire", and no sibling relationship is implied. [5]. Progesterone: prevents conception and decreases sexual receptibility of the mare to the stallion. Progesterone is therefore lowest during the estrus phase, and increases during diestrus. It decreases days after ovulation, when the corpus luteum begins to decrease in size. In addition, the maternal grandfather of a horse has a special term: damsire. Colts are carried on average about 4 days longer than fillies. [9]. Anas, "duck" and Ancient Greek πλατυρυγχος, platyrhynchus,

10 "broad-billed" (from πλατύς, platys, "broad" and ρυγχός, rhunkhos, "bill"). [5]. This is quite unusual among such different species, and is apparently because the mallard evolved very rapidly and recently, during the Late Pleistocene. [12]. I film stuff like this for a living. Three Octopi getting down and dirty having sex in the crystal clear waters of the Andaman Sea near Phuket, Thailand. Its amazing to see them changing colours and chasing each other for some love. If anyone is thinking about coming to work in Thailand to train as a scuba diving instructor contact me. Masle (male) has also been proposed as an influence. [10]. Both male and female mallards have distinct iridescent purple-blue speculum feathers edged with white, which are prominent in flight or at rest but temporarily shed during the annual summer moult. [27]. Mares due to foal are usually separated from other horses, both for the benefit of the mare and the safety of the soon-to-bedelivered foal.

He gave it two binomial names: Anas platyrhynchos and Anas boschas. [3]. Its legs and bill are also black. [28]. The genome of Anas platyrhynchos was sequenced in [6]. Examples of this rule in birds are rare as they lack external ears, but the bill of ducks is supplied with a few blood vessels to prevent heat loss, [41]. Colts are carried on average about 4 days longer than fillies. [9]. ] When incubating a nest, or when offspring are present, females vocalise differently, making a call that sounds like a truncated version of the usual quack. They hiss if the nest or offspring are threatened or interfered with. When taking off, the wings of a mallard produce a characteristic faint whistling noise. [37]. When Photographer Covers

Some breeds denote the country, or state, where conception took place as the origin of the foal. [. The gestation period lasts for about eleven months, or about 340 days (normal average range days).

While horses in the wild mate and foal in mid to late spring, in the case of horses domestically bred for competitive purposes, especially horse racing, it is desirable that they be born as close to January 1 in the northern hemisphere or August 1 in the southern hemisphere as possible, [8]. After birth, a foal's navel is dipped in antiseptic to prevent infection, it is sometimes given an enema to help clear the meconium from its digestive tract, and the newborn is monitored to ensure that it stands and nurses without difficulty. ] Exercise in excessively high temperatures has been suggested as being detrimental to pregnancy maintenance during the embryonic period; [12]. GnRH ( Gonadotropin releasing hormone ): secreted by the hypothalamus, causes the pituitary to release two gonadotrophins: LH and FSH. Prostaglandin: secreted by the endrometrium days following ovulation, causes luteolysis and prevents the corpus luteum from secreting progesterone. On the other hand, some breeders, particularly those in remote areas or with extremely large numbers of horses, may allow mares to foal out in a field amongst a herd, but may also see higher rates of foal and mare mortality in doing so. Once fertilized, the oocyte (egg) remains in the oviduct for approximately 5.5 more days, and then descends into the uterus. The initial single cell combination is already dividing and by the time of entry into the uterus, the egg might have already reached the blastocyst stage. Effects on the reproductive system during the estrous cycle. Progesterone: prevents conception and decreases sexual receptibility of the mare to the stallion. Progesterone is therefore lowest during the estrus phase, and increases during diestrus. It decreases days after ovulation, when the corpus luteum begins to decrease in size.
