Benefits of Ammonium Chloride for Goats, Animal Sake

Minerals are very important for keeping an animal healthy. But sometimes, the body cannot process or absorb certain minerals properly. When that goes wrong, stones can form inside the body. When stones grow in a goat's urinary tract, the condition is called urinary calculi. The stones make it hard (or even impossible) for the goat to pass urine. Ammonium chloride is used to prevent and treat this condition.

Who's at Risk?

Urinary calculi mostly affects male goats. Females can get the condition too, but it is rare. Why are males more at risk? It comes down to body shape. Male goats have long urethra tubes that twist and turn. Female goats have a short, straight urethra. Because of all those bends, it is much harder for solid particles to pass through a male goat's urethra than a female's.

Even among males, some are more at risk than others. Wethers (male goats that have been castrated) get the condition far more often than bucks (uncastrated males). Read our guide on pygmy goat care to understand how size and breed affect health needs.

A goat eating hay from a wooden trough, diet is the main factor in preventing urinary calculi. — Diet is the #1 factor. Too much phosphorus in grain concentrate is a common trigger.

Causes

Diet is the biggest cause of urinary calculi. Goat feed needs the right balance of calcium and phosphorus. The ideal ratio is 2:½, and it should never fall below 1:1. Too much phosphorus is the main culprit. Many producers and show-goat owners feed their animals grain concentrates. When those concentrates are too high in phosphorus compared to calcium, stones start to form.

What if your goat eats hay instead of grain concentrate? Get the hay and water tested for mineral levels. Some hays (like Bermuda grass) are naturally high in phosphorus. If the hay was fertilized with chicken litter, the phosphorus level goes even higher. Adding limestone (calcium carbonate) to the feed can bring the calcium:phosphorus ratio back to the right level.

In rare cases, the water a goat drinks can also play a role. If the water is too acidic, it may trigger urinary calculi. Check the pH level of your water, it should be neutral.

Prevention

Vets recommend ammonium chloride as one of the best tools to prevent (and treat) urinary calculi. Most producers add it to the diet of meat-type goats that eat a lot of grain. Here is how it works: when the urine's normal pH shifts, minerals start to crystallize and clump together into stones. Ammonium chloride lowers the urine pH, making it more acidic. That acidity stops the crystals from forming in the first place.

The table below (based on vet guidelines) shows how much ammonium chloride to include in a goat's diet:

Ammonium Chloride	Pounds per Ton of Feed	For Topdress Feed
0.50%	10 pounds	½ tsp (2.27 g)
1.00%	20 pounds	1 tsp (4.54 g)
1.50%	30 pounds	1½ tsp (6.81 g)

Along with ammonium chloride, here are other steps you can take to prevent urinary calculi:

Make sure the goat's diet has a calcium:phosphorus ratio of 2:1.
Always give your goat access to clean, fresh water.
Delay castration in lambs for as long as possible. After castration, the body stops producing testosterone, and without testosterone, the urethra cannot grow to its natural, full diameter.
Adding 3-4% salt to the diet encourages the goat to drink more water. This helps keep the urinary system flushed and healthy.

Treatment

A farmer ensuring goats have access to clean, fresh water, an important step in preventing urinary calculi. — Clean water access is one of the simplest and most effective prevention steps.

If a goat's urine flow is completely blocked, take the animal to the vet immediately. Surgery is the only way to clear a full blockage.

If the blockage is only partial, there may be a gentler option. An oral drench (a liquid mixture given directly into the goat's mouth) can help dissolve the stones. Use the table below to mix the right dose. The amounts are based on a mixture of 0.26 grams of ammonium chloride per kg of the goat's body weight.

Weight of Goat	Amount of Ammonium Chloride per Gallon of Water
30 pounds	0.78 lbs
45 pounds	1.17 lbs
60 pounds	1.56 lbs

Give the goat 40 cc of the mixture. Keep in mind that ammonium chloride can be toxic in high doses, but when urinary calculi are severe, it may be the only option available. Always consult your vet before giving this treatment.

Frequently Asked Questions

What does ammonium chloride do for goats?

It acidifies the urine, preventing minerals from crystallizing into bladder stones (urinary calculi).

Which goats are most at risk for urinary calculi?

Wethers (castrated males), because their urethra doesn't grow to its full natural diameter after castration.

What calcium-to-phosphorus ratio should goat feed have?

Ideally 2:1, never below 1:1. Too much phosphorus is the main dietary cause of urinary calculi.

Can ammonium chloride treat an existing blockage?

For partial blockages, an oral drench may help dissolve stones. A complete blockage requires immediate veterinary surgery.

Glossary

Term	What It Means
Urinary calculi	Mineral crystals that clump together and form hard stones inside a goat's urinary tract or bladder.
Wether	A male goat that has been castrated (had its reproductive organs removed). Wethers are the highest-risk group for urinary calculi.
Urethra	The tube that carries urine from the bladder out of the body. Male goats have a much longer, more winding urethra than females.
pH	A measure of how acidic or alkaline a liquid is. A lower pH is more acidic. Ammonium chloride lowers urine pH to stop crystals forming.
Calcium:phosphorus ratio	The balance of two key minerals in a goat's diet. The ideal ratio is 2:1 (twice as much calcium as phosphorus).
Oral drench	A liquid medicine given directly into a goat's mouth using a syringe or drenching gun, used to treat partial blockages.
