Copper sulphate in dog food

[Walksalot]

I was reading the ingredients in the dog food I buy and noticed copper sulphate listed in the ingredients. The guy at the pet store emailed the company and had them send me the reason copper sulphate is in the food. Here is their answer. I thought I would post this FYI.

Water is a poison at too high of levels...

Thanks for your question and interest in our food. Copper is an integral component of enzymes that catalyse oxidation reactions. These include monoamine oxidase, lysyl oxidase, ferroxidase, and cytochrome C oxidase. Physiologically, copper serve many functions. For example, lysyl oxidase plays an important role in connective tissue formation. By virtue of its role in ferroxidase enzymes, copper is involved in iron metabolism and hematopioesis. It is also essential through its role in tyrosinase for melanin pigment formation and thus for normal hair and eye colour. Through its role in cytochrome oxidase, it is involved in myelin formation and other aspects of central nervous system functions, as well as in oxidative phosphorylation. As a cofactor of the enzyme superoxide dismutase, copper also is critical for appropriate defence mechanisms against oxidative damage.

Copper is deemed a requirement by NRC and is not found in high concentrations in many of the ingredients used in the manufacture of petfoods. Of all the sources, copper proteinate and copper sulphate have the highest bioavailability. Other sources like cupric oxide, cupric chloride, and cupric sulfate pentahydrate are not very bioavailable and are not recommended to be used at all. NRC have deemed that there is no documented safe upper limit for dogs, as they have tested it at over 250mg/kg over extended periods with no noticeable adverse affects although AAFCO suggest a maximum of 250 mg/kg. The minimum requirement is at about 8 mg/kg, typical analysis of our food is between 30 and 40 mg/kg.

Hope this answers why we use copper sulfate. Let me know if you have further questions.

Whats the brand?

Just read the box of Milk Bone dog treats. It has copper sulphate also. Not sure about the Nutro. I havent got a bag to check. I used to run an extruder to make dog and cat kibble. Never got any of the mixxer ingredients sheets to see if it was in any of the product.

Seems to to me it's a necessary ingredient in dog food. Why would the
manufacturers add a really expensive additive if it wasn't needed?

It's the SIZE not the amount...

Well I won't be sprinkling any on my raw dog food anytime too soon.

It is also very good for killing moss on your roof.

They used to use it ("bluestone") as a preservative for cotton fishing nets. My dad always said it made any cuts on your hands swell up and look very strange, but then heal up really fast. It has some antifungal/herbicidal properties.
