Trace Elements in Abiotic and Biotic Environments

Manganese deficiency is dangerous for animals. Mn-deficient animals exhibit
impaired growth, skeletal abnormalities, reproductive deficits, ataxia of the newborn, and defects in lipid and carbohydrate metabolisms. Its nutritional deficiency,
in cattle, sheep, and pigs may cause infertility and skeletal deformities, including
enlarged joints, pain, knuckling at the fetlocks, and twisting of the legs. It is a rare
deficiency in dogs and cats. For animals, Mn is an essential component of over 36
enzymes, which are used for the carbohydrate, protein, and fat metabolism.
For some animals, Mn lethal dose is quite low. Excess Mn can cause lung, liver
and vascular disturbances, declines in blood pressure, failure in the development of
animal fetuses, and brain damage. Its excessive intake may present a cardiovascular
hazard (ATSDR 2012b).
