Nigerian Dwarf Bucks and wethers are fed only grass type hays such as forage hay or Bermuda grass. Because of the urinary tract of male goats, wethers are at higher risk of developing urinary calculi or ‘stones’. The development of these stones can cause an obstruction in the urethral process (a small tube that acts as a urine sprayer). In our feeding practices we avoid feeding legume hay and grain to our wethers and not frequently to our bucks.
Preventing Calculi buildup
There are a couple of things you can do to detour calculi build up. You can supplement their fed with aluminum chloride to counter act the acidity of the urine. Wait to castrate bucklings until they are 3-5 months old to give more time for the urinary tract to mature and open up more. Feeds should be lower protein with plenty of water available.

Make sure you have a freshwater delivery system as well. So as you prepare your farm now is the perfect time to run some PVC and setup a livestock waterer.
ts can live in a simple shelter such as a medium to large dog igloo to a goat condo! What is of imperative importance is that they are able to get out of the weather. There is a common saying among goat owners, “a wet goat is a dead goat.” That being said, goats absolutely hate getting wet! Whatever shelter you choose to buy/build it will need to be mucked out weekly or sooner. When waste matter is left behind (especially if there is no air circulation) ammonia fumes build up and linger at the bottom of the enclosure. The build up and constant inhalation of these fumes can/will irritate the goats lungs and they can develop pneumonia. Pneumonia in goats more times than not results in the death of the goat.
We recommend a bowl type that mounts to a fence and includes a float and if you have high water pressure (above 50 PSI) use interactive watering devices like a paddle water bowl that requires your goat to push on a level with their nose. Put these waterers high enough so they cannot poop in them. Also be prepared to use a cinderblock so your bucklings and doelings can reach the water until they grow taller.
feeding grain, but if you have many goats I would consider a trough that mounts to the fence. Goats are messy with their hay so use a large trough or a hay feeder.
