The short version

Most goat health problems trace back to mineral deficiency before they trace back to anything else — skin conditions, failure to breed, lost pregnancies, dull coats. Give your goats the highest-quality minerals you can afford, either as a quality premix or a cafeteria-style mineral bar where each mineral is offered separately and the goat self-selects. Goats also need more copper than most livestock; if their minerals and forage aren't covering it, you'll see a faded coarse coat, hair loss on the bridge of the nose, and a "fishtail" — and the fix is a copper bolus, which most goats need no more than once every six months to a year. You can pay for minerals on the front end, or pay the vet a lot more on the back end. Those are the options.

​

Why minerals come before almost everything else

Here's the thing the insta-guides skip: a goat showing a "mystery" health issue usually isn't a mystery at all. Deficiencies in essential minerals show up as everything from skin problems to does that won't settle when bred, or can't hold a pregnancy. Before industrialization fragmented how animals lived, a herd ranged across varied ground and self-corrected by browsing different plants rooted in different soils. Our goats live on our acreage, eating what our soil grows — and our soil, like most soil, doesn't have everything they need. So the minerals have to come from us.

That's not a sales pitch for any product. It's just the math: you can spend the money up front on prevention, or spend significantly more later in vet bills and medications chasing symptoms.

Premix vs. the cafeteria mineral bar — what Petunia taught me

A quality premix is a perfectly good place to start, and for plenty of herds it's enough. But goats are individuals, and their needs differ — by season, by stage of pregnancy, by lactation.

That was Petunia's problem.

 

My theory: she needed more of one or two particular minerals than the premix delivered. So in her attempt to get enough of those, she was overdosing herself on all the others — which is a known cause of diarrhea.

The premix made her choose between deficiency and overdose. She kept choosing overdose.

The fix was the cafeteria-style mineral bar: each mineral offered separately, so every goat picks what she actually needs. I'd been holding out because the initial cost stung, but a few goat breeders I respect kept telling me high-quality minerals were the foundation of herd health, and they were right. Iscrewed some cheap plastic cups to the wall with washers, set out eighteen minerals plus plain salt, and the whole herd gathered around to see what the fuss was about.

Watching them pick and choose was genuinely incredible. Petunia never had the diarrhea again. Not once. Her coat improved and she hit a massive growth spurt shortly after. Every goat in the herd improved, but she was the most telling. And it's fascinating to watch their preferences shift with the seasons and with where each doe is in pregnancy or milk. I will likely never go back.

If the cafeteria bar isn't in the budget yet: don't let perfect kill good. Plain salt offered free-choice at all times, plus Icelandic kelp when you can afford it, will help tremendously.

Copper: the mineral goats need more of than almost anyone else

Goats have a higher copper requirement than most other livestock — particularly sheep. (That's exactly why you never let sheep into the goat minerals: what's nutrition for a goat is copper toxicity for a sheep. If you run both species, this one matters.)

When forage and minerals aren't covering a goat's copper needs, the goat will tell you. You just have to know the language:

• A coarse, rough, dull coat losing its color. A black goat fades to a coppery red. A brown goat goes tan. White goats are the hard ones — there's nowhere paler than white to fade to, so watch the other signs closely.

• Hair loss on the bridge of the nose.

• Fishtail — hair loss at the tip of the tail that splits it into two "fins," like a fish.

If you're seeing these, it's time for a copper bolus.

​

How to give a copper bolus (and the Fig Newton trick)

A copper bolus is a capsule full of tiny copper rods. It breaks open in the rumen, and the copper dissolves slowly, feeding the goat's system over the following months. Three ways to get it in:

1. The bolus gun. Place the bolus far enough back in the throat that swallowing is the goat's only option. Effective, not anyone's favorite — yours or the goat's.

2. Break the capsule open over feed. Works fine, with one rule below.

3. The Fig Newton trick. Hide the whole bolus inside a treat your goat loves — a Fig Newton or a ball of rolled oats and molasses. The goat thinks she's getting dessert. You know she's getting her copper. Everybody wins, and nobody got wrestled.

The one rule, however you administer: one goat, by herself, so you know with certainty that goat got the full dose. A bolus split across the herd helps no one.

Then write it down. Note the date you bolused each individual goat. Most goats don't need more than one bolus every six months to a year, and "I think I did her in... spring?" is not a record. 

The payoff is fast and visible: within a few weeks of bolusing a deficient goat, you'll watch the symptoms dramatically improve. The coat is the report card.

Common mistakes I see

1. Buying cheap minerals to save money. This is the most expensive money you'll ever save. The deficiency bill comes due as vet visits.

2. Blaming the goat instead of the system. A goat with chronic loose stool at the mineral feeder, a doe that won't settle, a faded coat — these are usually the program, not the animal. Petunia looked like a problem goat. She was a problem setup.

3. Letting sheep into goat minerals. Goat-level copper can kill a sheep. Separate access, full stop.

4. Bolusing the herd, recording nothing. If you don't know who got what and when, you can't read what happens next.

When to call your vet

Mineral work is preventative — but acute symptoms aren't a wait-and-see. Severe or persistent diarrhea, especially in a kid, can dehydrate a goat fast (Petunia's first episode genuinely scared me). A goat that's deficient and declining may have a parasite load or something else stacked on top. Minerals are the foundation, not the whole house — when a goat is going downhill, get your vet or an experienced mentor on the phone.

Going deeper

Minerals are one piece of the feeding picture — they work alongside forage, hay, and the grain question we covered in Do Goats Really Need Grain?. The full feeding-and-health program — what we feed, why, and how it changes through the season — is laid out in Homesteading with Dairy Goats, including the parts where I got it wrong first.

Quick answers

How do I know if my goat is copper deficient? Look for a coarse, dull coat losing color (black goats fade to red, brown goats to tan), hair loss on the bridge of the nose, and a "fishtail" — hair loss at the tail tip that splits it into fins.

 

How often do goats need a copper bolus? Most goats need no more than one bolus every six months to a year, and only if minerals and forage aren't meeting their copper needs. Record the date for each goat.

 

Can sheep eat goat minerals? No. Goats need far more copper than sheep, and goat minerals can cause copper toxicity in sheep. Keep mineral access separate.

 

What's the easiest way to give a goat a copper bolus? Hide the bolus in a treat the goat loves — a Fig Newton or a ball of rolled oats and molasses — and give it to that goat alone so you know she got the full dose.
