Copper deficiency, or hypocupremia, is defined as insufficient copper to meet the body's needs, or as a serum copper level below the normal range. [1] Symptoms may include fatigue , decreased red blood cells , early greying of the hair, and neurological problems presenting as numbness , tingling, muscle weakness, and ataxia . [ 2 ]
Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet , impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
Cattle, sheep, goat, and other ruminants that are diagnosed with PEM or pre-PEM suffer opisthotonus, cortical blindness, disoriented movement, and eventually fatality, if left untreated. [1] Current data shows that the onset of PEM can range from birth to late adulthood.
Copper deficiency is a major issue in global food production, resulting in losses in yield and reduced quality of output. Nitrogen fertilizers can worsen copper deficiency in agricultural soils. [citation needed] The world's two most important food crops, rice and wheat, are highly susceptible to copper deficiency.
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form.
In sheep and goats, the lesions mostly appear on or near the hairline and elsewhere on the lips and muzzle. In some cases the lesions appear on and in the nostrils, around the eyes, on the thigh, coronet, vulva, udder, and axilla. In rare cases, mostly involving young lambs, lesions are found on the tongue, gums, roof of the mouth and the esophagus
Familial benign copper deficiency, also known as Familial benign hypocupremia is a rare genetic disorder which is characterized by hypocupremia that causes symptoms such as epilepsy, hypotonia, seborrheic skin, thriving failure and mild anemia. [2] Radiological findings include tibia and femur spurring. [3]
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
