 Anyone raising goats should be aware of those two little words that cause such a horrible problem. Whether you have backyard goats or a whole herd of show animals, you have or will have to deal with Urinary Calculi (UC) at some point. So what is this menace, how do we treat it and better yet how do we prevent it from happening in the first place. With winter coming or in some parts of the country already there, this problem will become more prevalent due to your animals not consuming large amounts of water. *We get commissions for purchases made through links in this post.

(These are commonly referred to as Kidney Stones in humans.) Most often these crystals are formed due to a metabolic imbalance in the body caused by feeding too much grain to bucks and wethers. This is most commonly found in show wethers, or bucks being given large amounts of a high-concentrate feed along with low amounts of roughage or hay. The goat urinary tract consists of 2 kidneys, the ureters, a bladder and urethra, along which urine flows during urination. Male ruminants have a long narrow urethra which end in the urethral process which is particularly narrow. Fine calculi often form in the urinary system, but are often excreted with the urine; however, in males they can become trapped and block the normal flow of urine. As the pressure builds up from the blockage, if undetected, it will eventually rupture the urethra, the goat will rapidly deteriorate and die, hence it is important to detect urinary tract issues early.  Urinary calculi or stones are caused by the precipitation of minerals. High levels of minerals tend to crystalize and aggregate in the urine forming calculi. In goats calculi usually comprise of phosphate salts, especially apatite (calcium phosphate) or more commonly struvite (magnesium ammonium phosphate hexahydrate). Increased urine concentration as a result of decreased water intake, urine stasis can recur and water loss all increase urine pH favoring the formation of phosphate calculi. However, the diet is considered the most important risk factor associated with urolithiasis. Prevention of Urinary Calculi:A large part of this problem is the early castration of bucks/wethers. When bucks are wethered at an early age, they lose the hormones needed to fully develop their urinary tract, basically once the testosterone is gone the urinary tract quits growing. If your wether was castrated early though there is still hope that he will be fine, with some due diligence on your part. First things first, if you have wethers or even bucks making sure their diet is high in roughage and low in grain is imperative. Some breeds or bloodlines are more prone to urinary calculi just as some humans are more susceptible to having kidney stones. If you must feed a concentrate feed to your wethers or bucks:
All feed products are required to provide a feed tag on the bag. These ingredients are listed from highest concentration to lowest concentration in the bag of feed. So the first product on the list should say something like alfalfa, roughage source, etc. If the bag of feed's first ingredient is grain products, that is the product that is of high concentration in the bag. You may have an issue finding a roughage based feed at your local feed store so the next best thing to look for is Ammonium Chloride. Ammonium Chloride is a common ingredient in meat goat feeds because of the high incidence of Urinary Calculi seen in market animals. These market animals are usually pushed to develop quickly by giving a high concentrate feed with very little hay or roughage. Ammonium chloride is a common ingredient in most commercially based meat goat feeds. If you still have an issue with finding one containing the Ammonium Chloride, you can add Ammonium Chloride into your goats feed 3 times a week. We like to feed a good feed that already has ammonium chloride in it to both our Boer and Nubian goats. NOTE: You must be careful when feeding Ammonium Chloride to any does in the pasture, especially milk animals. When does are lactating the ammonium chloride will not allow for the uptake of calcium and in later years does bones will become brittle if being fed a ration containing ammonium chloride. The key to avoiding Urinary Calculi is feeding the goat a proper diet. If you are experiencing Urinary Calculi in your goats, then you must change their feed regimen. Carefully read feed labels for proper calcium-to-phosphorus ratios (2-1/2 to 1 calcium-to-phosphorus is best). Some prepared goat feeds contain ammonium chloride in the formulation, but this is no guarantee that Urinary Calculi will be avoided. Most importantly, offer lots of free-choice forage/browse and good-quality small-stemmed grass hay and reduce the amount of grain concentrates being fed. Even though your wethers and/or bucks have plenty of pasture, they must be given a good quality hay source. Pasture is great for sustaining these guys but knowing from day to day what the quality of grass, browse, or other vegetation in your pasture is would be a daunting task. Make it easy and provide them with a supply of hay. Water is a huge issue, especially in the winter when water buckets are constantly freezing over. Goats love to have a fresh bucket of water every day. I scrub out the water buckets every morning. This will also encourage bucks and wethers to drink more water. Make sure buckets are kept clean, I mean clean enough for you to drink out of clean. Some studies are even indicating that large doses of medication can trigger bouts with Urinary Calculi, especially using antibiotics for an extended period of time. Because antibiotics can trigger metabolic changes in the diet it would be good to feed a product such as Fastrack to help keep the goat’s metabolism consistent.
Symptoms of Urinary Calculi:Things to look for if you suspect Urinary Calculi:
Treatment of Urinary Calculi:As with most other goat issues, prevention is a whole lot easier than trying to cure the problem, but if the problem occurs there are some things you can do although if the problem is not caught early enough these treatments may not work. Even veterinarians have limited success with treatment of Urinary Calculi. If your goat cannot pass ANY urine, he is completely blocked and THE VETERINARIAN SHOULD BE CALLED IMMEDIATELY. This condition is VERY painful and the goat could die soon from a bladder or urinary tract perforation/or rupture. Most common places for the urinary calculi to deposit are in the sigmoid flexure which is in the body cavity not as previously thought in the penis shaft. The veterinarian, depending on experience with goats, may try to reroute the urine flow from the penis. I have heard of this being done several ways, but be cautioned this is not to be taken lightly and most have to have constant treatment even after the surgery. Some veterinarians have re-routed the boy to basically become a girl, urinating out the back end. Others have put in a stint that the goat will urinate out of. The stint has to be monitored daily and cleaned regularly. Most veterinarians forward these surgeries onto a University clinic and charges can run upwards of $2,500. If your goat is not completely blocked there are several different treatments you can try. Depending on your confidence with treatments of your goats, you can try these yourself or go ahead and call the veterinarian. These treatments are suggestions from goat breeders and in no way guarantee the success of treatment of your animal. If your animal is at this stage his very life depends on treatment. First, for the pain management, giving an injection of an analgesic will help with pain and swelling. Next you will need to try one of these methods to see if the breakup of the calculi is possible. Home Remedy: As stated before, this is an option for treatment of Urinary Calculi. This treatment in no way guarantees the successful treatment of your animal.
 You might experience difficulty in dissolving this amount of ammonium chloride per gal of water. This will depend on the salinity of water being used. Doses were selected assuming a 20 cc drench gun would be used to administer the ammonium chloride solution. These doses will need to continue for more than one week. This will help to break up any remaining calculi. Please be aware that Ammonia toxicity could occur with prolonged use of this treatment, especially at the higher doses. ***It is imperative to NOT force your animal to drink large amounts of water during this time. If they are having problems urinating you are only making things worse and could cause a rupture. Urinary Calculi are a very real problem whether you raise backyard pets or show animals. Prevention is paramount when considering the treatment options and their limited success. If any animal is completely blocked as a veterinarian should be called immediately.
