Abstract:
... Selenium (Se) is a non-metallic trace element essential for normal cellular function, which has been linked with reduced risk of cancer, cardiovascular disease, cognitive decline and thyroid disease in humans. Se deficiency in livestock is associated with white muscle disease, retained placenta, ill-thrift and mastitis. Where Se status or bioavailability from the soil for plants is poor, livestock ...

Subject:
grasses; oxygen; permeability; plastics; silage; spoilage
Abstract:
... Thin plastic underlay films are commonly recommended to reduce spoilage and increase hygienic quality of commercial silages. However there has been a limited amount of research completed to ascertain the benefits of these underlay films, and even less to compare underlay films with differing oxygen permeability. This Short Communication comments on two papers recently published in this area, one i ...
