The normal equine bladder can accommodate 4–4.5L of urine. Horses usually urinate four to six times daily and, depending on size, will produce between 3 and 15L of urine.
Horses typically produce several quarts of urine every four hours, for a total of about 1.5 to 2 gallons per day. (By contrast, an adult male human pees 1 or 2 quarts per day.) The stream, usually one-third to a half-inch in diameter, can last up to 30 seconds. In general, the larger the animal, the more it pees.
Daily urinary volume averaged 15.6 L, with mean specific gravity of 1.028, osmolality of 1,040 mOsm/kg, and urinary flow rate of 1.24 ml/kg/hr.
On average, a horse produces 0.5 ounce of feces and 0.3 fluid ounce of urine per pound of body weight every day. A 1,000-pound horse produces about 31 pounds of feces and 2.4 gallons of urine daily, which totals around 51 pounds of total raw waste per day (Figure 1).
Normal urine production is typically 15-30 ml/kg daily, which for an average 500kg horse totals around 15 litres. Measuring urine output is not easy, in practical terms, but this equates to a horse peeing around five or six times per day, with a normal stream of urine lasting 30 seconds.
The most frequent reason that horses urinate excessively is because they drink excessively. In most cases, you will notice increased water consumption along with increased urination. Excessive drinking is most commonly a habitual behavior known by vets as psychogenic polydypsia.
The more protein in the horse's diet the more urea and ammonium — two breakdown products of protein — he will produce and excrete. So that explains the ammonia smell you might notice in the stable.
A 1,000 pound horse will defecate approximately four to thirteen times each day and produce approximately nine tons of manure per year. The 1,000 pound horse will produce, on the average, 37 pounds of feces and 2.4 gallons of urine daily, which totals about 50 pounds of raw waste per day in feces and urine combined.
Regular horses and racehorse pee the same amount. The difference is the use of Lasix in racehorses which causes them to pee excessively. Lasix use can be found in equine events other than racing.
On a very hot day, how long would it take for a horse to become dehydrated? “An idle horse requires approximately 5 L water/100 kg body weight,” Janicki says. “Typically, for a 1,100-pound horse, that would be around 25 L (6.6 gallons) of water per day.
The urinary bladder can store up to 500 ml of urine in women and 700 ml in men. People already feel the need to urinate (pee) when their bladder has between 200 and 350 ml of urine in it.
PMU is used to produce estrogen and hormone-replacement drugs such as Premarin, Prempro, and Premphase, and DUAVEE, a “Prempro Lite” which contains Premarin. PMU drugs are made by keeping mares constantly pregnant and collecting their estrogen-rich urine.
The average horse passes manure anywhere from 4 to 12+ times a day. Stallions and foals often defecate more frequently than mares and geldings; stallions often “scent mark” their territory, and foals need to pass more waste because of their liquid diet.
Diarrhea and Frequent Urination
Horse diarrhea can also be caused by a poor diet, which is a common cause of stress in horses. A stressed horse may urinate frequently to relieve their stress and become more stressed if they are in a place where they cannot relieve themselves, such as a trailer.
As a result, it is quite normal for a horse to poo (defecate) 8-12 times a day and produce anywhere from 13 to 23 kilograms of poo a day. Changing your horse's diet to large infrequent meals or from a fibre to a grain-based diet can change how many times and what your horse's poo may look like.
A:Geldings are just like boys–they may urinate standing up or sitting down, or even walk while urinating. So this odd behavior may be normal for your new gelding.
During the peak of estrus, the mare may sniff, lick, or nuzzle the stallion. A mare in heat will also urinate frequently, particularly if a stallion is teasing her to test her receptiveness. She is also likely to raise her tail and assume a breeding stance.
Castration or “Gelding” of colts or stallions is the most common surgical procedure performed in horses. Male horses that are not intended for breeding may be castrated for a number of reasons, however the most common reason is to avoid or reduce aggressive stallion behaviour.
Difficulties in urinating such as straining or adopting the stance and then dribbling or not passing any urine, or too many short urinations are usually signs of cystitis (bladder inflammation and infection), urethritis (infection of the urethra) or urinary calculi (stones).
Occasionally the docs will see mucus-covered fecal material. This can look like long stringy worms or even spaghetti woven in and around the fecal balls. Mucus in horse poop means that the manure has been sitting in the gastrointestinal tract for too long because there's not enough moisture to move it through.
Horse manure is unlikely to spread any disease to people, including bacterial problems with E. coli, which is killed in sunlight. Human and dog waste are far more likely to spread disease and parasites to humans.
Horses can identify some colors; they see yellow and blue the best, but cannot recognize red. One study showed that horses could easily tell blue, yellow and green from gray, but not red. Horses also have a difficulty separating red from green, similar to humans who experience red/green color blindness.
Normal horse urine sometimes turns red or brown after standing for a while. This is due to the presence of oxidizing agents termed “pyrocatechines. It can happen year round (the same process can turn stall shavings red), but is especially obvious against the white snow!
Notice that recognition when you approach a horse; the horse reaches out its muzzle to take in your scent by sniffing you. As with other animals, extending the back of your hand is a good way to let the horse get to know and trust you, and accept your presence as a herd mate and not a predator.
Musk Ox. These furry, horned mammals that inhabit the Arctic produce a smelly 'musk' from their urine.
