There are several articles out there about zinc deficiencies in alpacas. Some make a big deal out of it while others say that hardly any alpacas have an issue with low zinc levels. Some say some skin problems or the lack of hair on the nose of a black alpaca can be attributed to a zinc deficiency while others state it’s itching and flies or mites.
I’m not here to give medical advice but would like to let you know what method I use to make sure my alpacas have a low dose of zinc in their diets. Better yet, it’s probably the cheapest supplement program you’ll hear of I’m sure.
What’s my solution? I use Galvanized Carriage Bolts. A Galvanized bolt has a zinc coating and when submerged, the zinc slowly dilutes into the water. I like this method because all alpacas will drink water so you’re sure they are getting a low zinc dose with it.
I use (2) ½” carriage bolts per 5 gallons. Depending on how often you have to fill/change your water, the bolts should last 6 months to a year. You’ll know when it’s time to change out your bolts because the zinc coating on them will no longer be visible.
