elements for normal bodily maintenance, growth, and reproduction. Minerals that are required in relatively large amounts are called major or macro elements. Those needed in small amounts are classified as micro, minor, or trace minerals. These terms, however, have no relationship to the metabolic importance of a mineral in the diet. A trace mineral can be as essential to the health and performa...

Introduction Pasture forage is the most significant contributor to the trace mineral nutrition of Florida's grazing beef cattle. Sandy, loworganic-matter soils have long been linked to the production of forages with low trace mineral content. In addition, the organic soils associated with the Okeechobee basin have been associated with the production of forages high in molybdenum, an antagonist ...

The objective of this study was to test the combined effect of offstream water and trace mineral salt on cattle distribution in a riparian meadow and its adjacent uplands. From July 15 to August 26, 1996 and 1997, three treatments were each randomly assigned to one pasture in each of three blocks. Sixty cow/calf pairs were then randomly allotted to the grazed pastures. The treatments included 1...

Minerals can be divided into two main categories, 1) macro-minerals and 2) micro or trace minerals. Macro minerals are minerals that are needed/required in relatively large amounts in comparison to micro or trace elements which are needed/required in relatively small amounts. In general macro minerals are required at concentrations greater than 100 ppm of the diet and are often expressed as a p...

OBJECTIVE An experiment was conducted to evaluate dietary supplemental trace mineral source and deletion on mineral content in tissues. METHODS Weanling crossbred pigs (n = 144; 72 barrows and 72 gilts; body weight [BW] = 7.4±1.05 kg) were used. A basal diet was prepared, and trace mineral premix containing either inorganic (ITM) or organic (OTM) trace minerals (Cu, Fe, Mn, and Zn) was added ...

2. Secondary mineral deficiencies are by far the most common of the two. Secondary deficiencies are derived from the consumption of one or more mineral antagonists that interfere with the normal metabolism of another mineral. A simple mineral evaluation of a feedstuff may suggest that adequate trace mineral concentrations are present; however, the presence of a mineral antagonist will decrease ...

The optimum value of trace minerals is how well they can serve their biological function in an animal’s body. For trace minerals to keep an animal in good health and performing to their genetic potential, they have to be available for absorption in the small intestines. There are a multitude of compounds and factors that will interact with individual trace minerals that have the potential to re...

Modern analytical techniques and instrumentation make it possible to accurately determine trace mineral concentration in feed and animal tissues. Unfortunately, however, such determinations provide no information on utilization of the minerals by animals. Utilization involves the concept of bioavailability and is critical in the selection of a suitable source of the mineral. In terms of trace m...
