Mineral deficiency? Or is it toxicity?

[GoldenTreePackGoats]

Thank you for sharing this stuff Nanno.

I get so confused with the copper deficiency stuff. All the vet's in this area tell me don't give copper boluses, and zinc instead. They have told me about entire herds dying from copper toxicity verified through necropsy's after only the standard 2 gram bolus. One of my own goats showed signs of copper toxicity which are similar to deficiency, and by giving him zinc he's made a full turn around, in fact my entire herd looks better. I guess maybe our area has high copper? Even though we get our hay from Eastern WA? It's kinda like our area is dark blue on the selenium map for high content but our hay is grown where there isn't any...
