Trace Mineral Bioavailability in Ruminants

lNHlBlTlON OF TRACE MINERAL METABOLISM IN RUMINANTS

Trace minerals exist in cells and tissues of the animal body in a variety of chemical combinations, and in characteristic concentrations, depending on the trace mineral consumed and the tissue in which the trace mineral is metabolized (McDowell, 1992; Underwood and Suttle, 1999). Concentrations of trace minerals must be maintained within narrow limits in a cell (McDowell, 1989, 1992; Underwood ...

Trace Element Deficiencies in Ruminants

SOIL ASSOCIATIONS The selenium content of most soils ranges from 0.1 to 2 parts per million. But in general soil selenium content by itself is not a good measure for the potential for occurrence of selenium deficiency in livestock grazing or consuming forages produced from it. Soil pH has a marked effect on the form of selenium present and its availability to the plant. In alkaline, well-aerate...

Trace Minerals Deficiency Diagnosis in Ruminants

Introduction Trace elements are essential in human and animal’s nutrition. They play a major role in health, immunity and reproduction. The production of milk or meat as well as the housing and management conditions of high-performing animals can generate oxidative stress and health troubles in cattle. Some trace elements and vitamins have an anti-oxidative action and increase immunity. The mos...
