Selenium (Se) is now recognised as an essential trace element for ruminants. It is required in cattle for normal growth and fertility and for helping to prevent other health disorders such as mastitis and calf scours. However, if given in too large a dose or more than one supplement containing selenium is given at the same time, it can be toxic.
Selenium deficiency is known to cause a variety of syndromes in cattle, sheep, goats and horses on grazing diets. In cattle, the principal clinical problem associated with selenium deficiency is white muscle disease (Nutritional Muscular Dystrophy), which causes cardiac muscle degeneration, but it is also associated with a range of sub-clinical.
Selenium from industrial wastes for grazing livestock book poisoning. Poisoning is most common in grazing animals such as cattle, sheep, and horses, which may forage on seleniferous grasses, forbs or shrubs.
Poisoning that might occur in poultry or swine would result from their being given seleniferous grain or some other seleniferous feed. Selenium intoxication has been outlined (by Rosenfeld. a source where toxic levels of selenium can be found.
Livestock that use stock dams, streams, or seep discharges in a seleniferous area for a water supply are at risk of chronic or acute selenium toxicity. Livestock should be excluded from water supplies that have a selenium concentration of ppm or.
The poisonous nature of many selenium compounds remained more or less a laboratory curiosity until the s, when it was discovered that selenium was the active principle in forages and grains that caused alkali disease in livestock raised in certain areas of the American great plains.
The practical Selenium from industrial wastes for grazing livestock book of this problem stimulated a great deal of research on both chronic and acute selenosis.
A recent article in the Canadian Veterinary Journal examined how common selenium deficiency occurred in beef cows across Western Canada. associated with selenium deficiency in Victoria, and production responses have not been obtained in supplementation trials on dairy cows in low selenium areas of South Gippsland (Caple et al.

Natural Selenium Coproduct Good for Sheep By Sandra Avant Febru A more Selenium from industrial wastes for grazing livestock book, longer-lasting selenium supplement for livestock may soon be available, according to a U.S.
Department of Agriculture (USDA) scientist. Animals as well as humans need selenium, a trace mineral and component of antioxidants, to stay healthy. Selenium is associated with a serum enzyme called glutathione peroxidase, so blood tests can be conducted to assess Selenium levels. Selenium from industrial wastes for grazing livestock book also can be measured from biopsied or post-mortem liver samples.
In some cases, a diagnosis of Selenium deficiency is made by the animal’s response to treatment. Treatment and Prevention. Judson et al., () showed that 5% selenium pellets (10g gross weight) administered to sheep grazing selenium deficient pasture in South Australia showed raised blood selenium levels for up to weeks.
Lambs born from the treated ewes showed raised selenium Selenium from industrial wastes for grazing livestock book for 4. Analysis of variance of data for Se concentration in forage plants and blood plasma of three classes of Kajli breed of sheep is shown in Table 1 and the mean data for forage and plasma selenium concentrations with respect to seasonal influence and sampling intervals on forage and plasma Se are presented in Fig.

A survey was conducted in Southwestern, Punjab, Pakistan during two different seasons to assess the status of selenium of three different classes of grazing sheep.
Blood plasma from lactating, non-lactating and male sheep were collected four times monthly in winter and summer seasons and analyzed for selenium concentration. Seasonal variations were found for plasma selenium : Zafar Iqbal Khan, Kafeel Ahmad, Muhammad Danish, Muhammad Aslam Mirza, Farhad Mirzaei.
Selenium (Se) is a trace element that plays an important role in the health and performance of animals. In cattle, selenium deﬁciency can have economically signiﬁcant impacts such as reduced a farming region . In a study conducted during the grazing season, Ceballos-Marquez et al.

There is a marked seasonal variation in the selenium nutrition of grazing livestock, with lowest levels occurring in spring and summer. Unsupplemented cattle at pasture, such as late lactation or dry cows and cycling heifers are much more likely to show signs of selenium deficiency than housed cattle on a balanced mineral ration.
Distribution 39 livestock and poultry producing the food. Plant and animal wastes return selenium to the soil. Oceans, seas, and lakes obtain selenium from inflowing waters, with some of the element deposited in the sediments.

Veterinarians should be aware that many selenoenzymes exist, some with functions quite distinct from the antioxidant role of glutathione by: When ruminants consume selenium from plants it is stored for a short period in the body, mainly in the liver, before being flushed out in normal waste.
A continual dietary supply ensures the best possible production. What happens if sheep and cattle don't get enough.
Selenium deficiency has serious repercussions for your grazing animals. Selenium poisoning occurs in the areas that have soils high in selenium. Both indicator and secondary selenium-accumulating plants grow in these areas. Astragalus bisulcatus, two-grooved milkvetch, is a selenium-accumulating plant.
