CopperCopper (Cu) is another important mineral. It is used in the creation and maintenance of elastic structures such as connective tissue and other structures. This is especially important in growing horses, as the bone collagen is one of these structures that relies on the presence of Cu to develop correctly.
Another important function of Cu is to help create red blood cells. And lastly, it helps keep the central nervous system running correctly. Cu is one mineral that can be highly influenced by other minerals. The following mineral forms can all reduce the absorption rate of Cu to varying degrees:
Dietary SourcesCommon feedstuffs that are fed to horses vary widely in their Cu content. Can molasses has one of the highest concentrations of Cu. Due to this, its inclusion in feeds in a minimal amount can be beneficial. However, due to its high sugar content, if it is included in large amounts, the negatives outweigh the positives.The table below lists the Cu concentrations of some common feedstuffs:
As mentioned above, Cu is one of the minerals that can be easily influenced by other minerals. The most notable of these is zinc When large amounts of zinc are fed along with small amounts of Cu, a secondary Cu deficiency can be created. Copper DeficiencyBecause Cu is associated with connective tissue and bone, a Cu deficiency usually causes bone problems.Some common problems that have been linked to a deficiency include Developmental Orthopedic Disease. Copper ToxicityIt appears that horses are fairly tolerant of high Cu concentrations. When horses were given large amounts of Cu orally, no adverse reactions were seen.Thus, the maximum tolerable concentration for horses has been set at 250 mg/kg of ration. This level is way above the recommended intake level of 10 mg/kg dry matter. Cu, like the other minerals is essential to your horse's health. Now you know how your horse obtains and uses this mineral, as well as deficiency and toxicity information. Return to Minerals from Copper Return to Horse Nutrition Home |
