Using more bioavailable sources of trace minerals pays off
During recent years, the consumers' demands for sustainable animal production and safe foods put more pressure on the classical application of antibiotic growth promotors (AGP). Following the general trend in Europe and North America, a large part of Southeast Asia has also decided to move towards AGP-free animal production, despite no true alternatives have been confirmed.
Effect of diet supplementation with chelated zinc, copper and manganese on hoof lesions of loose housed sows
Marina Lisgara et al.
Hoof lesions are very common among sows and have been associated with lameness, early removal and compromised welfare and productivity. Although housing conditions and management can have an external effect on hoof health status, the role of trace mineral intake is vital in developing hoof structure and integrity. Therefore, the objective of this study was to investigate the effect of a diet supplemented with organic complexes of trace minerals (Zn, Cu, Mn), partly substituting their inorganic form, on hoof lesions of sows in three Greek swine herds.
The role of zinc, manganese and copper in rumen metabolism and immune function: a review article
Elhashmi Y. Hilal et al.
Trace minerals are dietary elements required by the body in minute amounts, ranging from 0.10 to 50.0 mg/kg dry matter in beef cattle diets. These trace minerals are all necessary for the biochemical processes of the body that support proper growth and maintenance. For example, Cu is necessary for the function of superoxide dismutase and its removal of toxic byproducts from metabolic pathways.
