Trace Hydrogen in Minerals [PDF]
, 1984 Trace hydrogen in minerals most frequently occurs bonded to oxygen. The resulting water and hydroxyl (OH-) affect and play a role in a variety of mineral properties and reactions. This thesis examines the occurrence of trace hydrogen in nominally anhydrous minerals, the mechanisms by which trace hydrogen participates in reactions and controls ...

Trace Mineral Feeding and Assessment
Veterinary Clinics of North America: Food Animal Practice, 2014Trace minerals are commonly supplemented in ruminant feeds as many common feeds are deficient in one or more of the trace minerals. The requirement of trace minerals needed to prevent classic nutrient deficiencies is well established, thus those cases most commonly occur when no supplement is provided.

Gastrointestinal irritation is a common entity in trace mineral toxicosis. To determine the extent of trace mineral involvement in west-central Nebraska beef calves, trace elements analyses were performed on 144 livers from perinatal calves submitted to the Veterinary Science Laboratory, North Platte, Nebraska during 1983 and 1984.

Trace Mineral Nutrition of Sheep
Veterinary Clinics of North America: Food Animal Practice, 2023Trace mineral nutrition of sheep often focuses on their greater susceptibility to copper toxicosis due to a lesser biliary excretion ability compared with other ruminants. Our understanding of sheep trace mineral requirements has improved for most elements allowing for a factorial approach to determining daily requirement instead of a dietary ...

Evaluation of Trace Mineral Sources
Veterinary Clinics of North America: Food Animal Practice, 2023Several trace mineral sources, including inorganic, numerous organic, and hydroxychloride sources, are available for dietary supplementation or inclusion in a free-choice supplement. Inorganic forms of copper and manganese differ in their bioavailability.

Trace Mineral Requirements for Athletes
International Journal of Sport Nutrition, 1994This paper reviews information pertaining to zinc, copper, chromium, and selenium requirements of athletes. Exercise increases zinc loss from the body, and dietary intake for some athletes, especially females, may be inadequate. Blood copper levels are altered by exercise, but there is no information to suggest that copper ingestion or status is ...

The authors survey in detail the role of the four trace elements in pregnancy, e.g. iron, manganese, magnesium and zinc, with regard to the development of congenital malformations and/or behavioural deficits, either prenatally or postnatally. It is maintained that these trace elements play a vital part during pregnancy and after birth.

Trace minerals in the nutrition of children
The Journal of Pediatrics, 1990Trace elements perform important functions in growth and development. However, little information exists about their dietary requirements during the demanding period of infancy. Opportunities to add to knowledge of the physiologic significance and dietary adequacy of trace elements in human nutrition are provided by recent analytic advances.
