Urinary Calculi, is a urinary-tract condition in goats and sheep, which prevents both urination and breeding in males. The twists and turns of the male urethra make passing solid particles difficult at best and impossible at worst. Urinary Calculi is a disease that can and does kill bucks and wethers quickly.
Why Does It Occur: Urinary calculi in goats and sheep is a common and mostly preventable livestock health issue. Other names for this condition are urolithiasis and water belly. When grain is heavily fed, forage is limited and minerals are out of balance, the perfect scenario is set up for stones and blockage to form in the urethra. The stones may be big enough to completely block the urethra or still allow a trickle of urine to pass through. Urinary Calculi is almost always the result of improper feeding by the producer. Proper calcium to phosphorus ratio in feed, hay and minerals is critical; this ratio should be 2 1/2 to 1. Although the disease is called Urinary Calculi, the real culprit is phosphorus -- specifically too much phosphorus in relation to the amount of calcium in the diet. Feeding too much concentrated feed and/or feeding concentrates with an improper calcium-to-phosphorus ratio is a major cause of Urinary Calculi. Overfeeding or improper feeding of concentrates causes solid particles to develop in the urine; these solid particles block the flow of urine out of the goat's body, causing great pain, discomfort and oftentimes death.
How to Prevent: diet is absolutely critical to help avoid Urinary Calculi. The wether & buck’s grain contains ammonium chloride which is the most important ingredient to ensure urinary tract health. It helps prevent and break up urine crystals. So make sure your male goats are getting a feed that has ammonium chloride in it. If not, buy the powdered ammonium chloride and add a pinch to each ration of grain each day. Do not give too much or damage will result. But this alone is no guarantee that Urinary Calculi will be avoided. Be very careful NOT to give more than 1 cup of grain per day to bucks/wethers. Do not feed Alfalfa to them either.
My Vet cautioned me against feeding alfalfa in any form, hay or pellet. Why? Alfalfa hay especially, is high in calcium and protein, which can lead to the formation of urinary calculi in male goatsl
The calcium in alfalfa hay can cause the pH of the urine to become more alkaline which can lead to the formation of urinary calculi.
It is very important to understand that feeding alfalfa hay or alfalfa pellets to male goats is not recommended at all.
Symptoms- How Do I Know If It's Urinary Calculi? Symptoms of Urinary Calculi include tail twitching in males, restlessness, anxiety and a "hunched-up" body posture as the animal strains to urinate. Catch it early! If your buck or wether does not come to be fed as usual and if you see them straining to pee, it's likely Urinary Calculi. Treatment must begin immediately.
UC Davis, College of Vet Medicine notes that confirming a diagnosis is as simple (yet costly & somewhat time consuming in a critical situation) as a physical examination and additional testing including bloodwork, X-rays, and an ultrasound. These tests help confirm that your buck or wether has a urinary obstruction due to bladder stones, and systemic compromise including electrolyte changes and increased kidney values consistent with not being able to urinate.
Some Vets will treat your goat urgently to stabilize him and provide urinary diversion (a way for urine to flow out of the body), by placing a tube through his skin and abdomen into his bladder to allow temporary urinary drainage. They may also surgically amputate his urethral process or pizzle as it is called (small, narrow appendage at the end of the penis where stones often lodge), allowing for a larger urethral opening.
The diagnostic tests results will show if the stones are consistent with struvite type stones, which can sometimes be dissolved with medical treatment. Your Vet may give IV fluids, muscle relaxants, pain medication, and urinary acidification to dissolve the stones, and antibiotics to prevent infection of the bladder. Fortunately, sometimes this process clears his stones, and he is able to urinate normally once again.
What if you can not afford all of that expense?
Treatment: With the assistance of my Vet I personally have developed a treatment that has worked both times this happened to a male goat at my farm.
