Why do lions grimace?
Flehmen response
Why do bulls smell and taste the urine of a cow or heifer?
This is called Flehmen response, and it's the bull's way of knowing whether the female is in heat or not. He does this by smelling and tasting the urine of the cow as she urinates, then he raises his head up as high as possible and curl his upper lip up to restrict airflow through the nasal passage. Subatmospheric pressure is created in the nasopalatine duct which allows the urine to be aspirated or "inhaled" through the duct and into the sensory surfaces of the vomeronasal organ. These sensory organs test for pheromone activity that is in the urine of the cow or heifer and lets the bull know whether she is ready to be serviced or not.
When a horse curls its upper lip?
when a horse folds up his/her upper lip it means he/she smelled somthing funny,like somthing he/she has never smelled before. My 4 year old mare somtimes does it when I ride her on the rode in my neighborhood.
How do cows mate?
Cows themselves ride each other if one or the other is in heat. However technically this is not mating, even though to the untrained dirty-minded individual it would seem otherwise. Cows ride each other if a bull or two are not present. Often the cow or heifer that is going out or coming into standing heat will ride other heifers or cows. However, if the heifer or cow is in standing heat then she will let other cows or heifers mount her without trying to move away. They rear up on their back legs (using their front legs to power themselves up, much like horses do) and settle their chest and shoulders onto the hindquarters of the female, so that their navel is in-line with the female's vulva. The back legs don't leave the ground, only their front legs do, since the back legs need to provide the mounting cow balance as she mounts and rides the female in estrus. The forelegs rest on the sides of the female directly above her flanks (often right before the hips), with the brisket resting on the tail-head and last couple vertebrae of her spine. The cow isn't putting all her weight on the hindquarters of the female being ridden, but enough so that she can rest her upper body on the female's hind quarters and, at the same time, take two thirds of her weight on her hind legs. Cows need bulls in order to be "serviced" properly. Bulls do a bit of foreplay first to see if the cow is in standing heat. This involves staying with the cow, licking and nuzzling her perineal region (clitoral and anal area), testing to see if she will let him ride her by resting his chin on her rump and jumping up on her, and doing the flehmen response when she urinates. The flehmen response is when the bull "drinks" her pee, then lifts his head up and curls back his upper lip to let some of the urine drain into a special cavity designed to test pheromone activity. If she is ready, she will stand for him in a stance that is only subtle to humans, but obvious to the opposite sex of her species. A bull's penis is not like a human penis where it remains outside of the body and increases in length and size by blood engorging it. A bull's penis can be retracted inside his body by a special piece of anatomy called the sigmoid flexture which forms an S-shape along the shaft of the penis. The SF allows the penis to be retracted within the sheath to inside the body, until erection occurs. Muscles known as the rectractor penis muscles keep the sigmoid flexture in place; they relax when the bull has an erection to service a cow or heifer. Erection in the bull involves the penis stiffening without any change in diameter. When mating occurs, the bull rides the cow in the manner described above (with the forelegs acting as a clasp on the cow's pelvis), and the erect penis is thrust into the cow's vagina. The must hold her back rigid to allow successful penetration. Copulation lasts for only 1 to 3 seconds where the semen is deposited into the fornix vagina (just before entering the cervix). The bull usually only thrusts himself into her once or twice, often leaping up with his back feet leaving the ground for a fraction of a second. A bull can have an average of 20 ejaculations before satiation, but he can also achieve 60 to 80 before exhaustion takes over. (One ejaculation yields 4 to 7 ml of semen, with 6 to 10 million sperm cells in each unit of seminal fluid.) The bull then dismounts and the cow is often seen with her tail held out straight with her back arched, sometimes with a little urine or excess seminal fluids being excreted, right after copulation. The reason she does this is because of the irritation she feels in her vagina after the bull's penis has been thrust in like it has. This post-copulatory behaviour only lasts for several minutes before she goes back to her normal way of life. However, a cow's tail will often stay out and a little crooked for 24 to 48 hours after copulation. This is a good sign to go by if you haven't seen the the cow getting bred by the bull. And as for the bull, he goes in search for another cow or heifer that is in need of his services. Odd times the bull will stay with the same cow, but usually when that cow is serviced, she is not in need of him anymore. When one of the sperm cells unites with the egg in the follicular tube of the cow, the egg them becomes a zygote which divides through cell division (mitosis) to create a blastocyst. Inside the blastocyst is the embryo, which is released into the uterus as the blastocyst ruptures. The embryo continues cell division, forming layers which predetermine the shape of the fetal calf's body parts and sex; also from the cell division, when the embryo attaches itself to the uterine wall, a placenta develops to continue to carry nutrients from the cow to the embryo-turned-fetus. The fetus continues to grow inside the womb, for an average total of 285 days from the point of conception. At the mark of 285 days (more or less, depending on the breed of the dam and sire and health and condition of the cow), a brand new baby calf is born into the world.
What is the reproduction of a male cow?
First off, "male cows" are referred to as bulls, not male cows. Now, a BULL has the reproductive organs that are similar to a human male, and are designed to create sperm and semen that are mixed together to be ejaculated into the cow when mating with the cow. A bull can mate anytime of the year any time he feels (except when he's injured, hungry, tired, or just doesn't have the libido), unlike cows, and often will breed around 50 cows in one breeding season.Bulls, like all male mammals, have testicles for producing sperm that hang below the body for adequate sperm production, and a penis that is used to inseminate a cow or heifer. The penis is housed in the sheath in the belly for protection, and often when a bull is aroused by pheromones from a female in heat, he will show the foreskin and penis from the middle of his belly where the sheath is. The penis is controlled by muscles called the Sigmoid Flexture muscles which cause the penis to retract into the bull's abdomen (thereby forming an S curve), and relax when the bull is sexually aroused and about to mate. When fully erect, the penis can get as long as 3 feet, and be 2 to 3 inches in diameter. Also, the penis, as mentioned previously, is naturally already hard and doesn't "get hard" like a stallion's or man's penis would. A stallion's or a man's penis becomes erect by a rush of blood and increased diameter of muscle veins in the penis. This does not occur in the bull. Nor does a bull's penis increase in diameter when erect; it literally stays as is when it reaches full erection.Before mating, a bull will foreplay with a cow or heifer first by following her around, licking her side, rump, genitalia, and even the udder, doing a Flehmen response when she urinates (the bull wrinkles his nose up and lifts his head up and back as far as he can, letting the urine drain into the Jacobson's organ in his nose to detect pheromone activity), and resting his chin on her hindquarters, attempting to mount her several times before he successfully breeds her. Often a cow or heifer that is in heat will mount the bull first before she stands to let him service her. If there are more than one bull attending to her, she will get bred by more than one bull.Bulls mount cows by propelling themselves by their hind-legs and letting their brisket rest on the rump/tailhead of the cow, thrusting his penis into the cow's vagina and giving one thrust that is forced by the bull by literally leaping with his hind legs (he'll only clear a few inches off the ground, btw) to thrust and ejaculate into the cow/heifer. Normal ejaculation will yield 7 mL of semen from a bull.

When a horse raises its upper lip to its nostrils this is called the what response?
If it's a stallion, this is known as the "flehmen response" where he lifts his head up and curls his lip back to let the urine that the stallion "drank" of the mare to test for pheromones to see if she is ready to breed or not.

How do wild horses mate?
Wild horses mate in the same way as domestic horses. A mare that is in heat will urinate and present herself to the stallion. The stallion will sniff the urine and then the mare, typically displaying the flehmen response. So long as the mare is receptive the stallion will then mount her and breed with her.

Why does a dogs lips quiver after it tastes another animal's or dog's saliva or blood?
Dogs can 'taste' scent. It's called Flehmen. By chattering the teeth, they are gathering the scent into the Jacobson's organ located on the roof of the mouth to 'taste' it, concentrating it, to get a better 'picture' of the animal or object they are sniffing. Sometimes it can get really intense causing saliva to drip or foam along with the chattering. Ultra excited as in a female in heat. Both males and females do it.

How can you tell your dog is ready to deliver?
When they are in estrus or in heat. Cows and ewes often act in a similar when they are in need of a partner to mate with; they are more vocal, more mobile and ride other herdmates or vice versa. If you have a bull or ram in with the cows or ewes, respectively, the bull or ram will follow the cow or ewe and court her by nuzzling her flanks and licking her clitoris, and will often do a flehmen response when she urinates. When she reaches standing heat, she will let the male mount her and inseminate her.
