It may be treated with selenium supplementation, but there is a 30–45% mortality rate. [7] Other sequelae include aspiration pneumonia, failure of passive transfer, and stunting of growth. Clinical laboratory changes include evidence of rhabdomyolysis (elevated CK and AST, myoglobinuria) and low blood selenium levels.
Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 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.
Grass tetany also called the staggers , is a metabolic disease involving magnesium deficiency, which can occur in such ruminant livestock as beef cattle, dairy cattle and sheep, [1] usually after grazing on pastures of rapidly growing grass, especially in early spring.
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.
A deficiency in vitamin A can lead to scaly of skin and other dermatitis-related issues like alopecia. [23] Vitamin E is an antioxidant. [24] Vitamin E neutralizes free radicals that accumulate in highly proliferative cells like skin and prevent the deterioration of fibrous tissue caused by these ionized molecules. [25]
Abomasitis (abomasal bloat) is a relatively rare ruminant disease characterized by inflammation of abomasum usually caused by larval development [1] in young calves, lambs, and goat kids. It occurs with gastroenteritis, but can also be a side effect of other diseases. However, it is seldom diagnosed as a separate condition.
