-	Besides sulfate (and chloride), iron in drinking water is probably the most frequent and important anti-quality consideration for dairy cattle. Whereas, iron deficiency in adult cattle is very rare because of abundant iron (Fe<sup>+3</sup>, ferric iron) in feedstuffs, excess total iron intake can be a problem; especially when drinking water contains high iron concentrations. Iron concentrations in drinking water greater than 0.3 ppm are considered a risk for human health, and are a concern for dairy cattle health and performance.	+	Besides sulfate (and chloride), iron in drinking water is probably the most frequent and important anti-quality consideration for dairy cattle.
