Trace Mineral Nutrition and Immune Competence in Cattle
نویسنده
چکیده
The importance of essential trace minerals on livestock productivity has been realized for several decades. In improved agricultural systems, the supplementation of essential trace minerals has lead to increased livestock production as measured by body weight gain and reproductive performance. Recently, the importance of trace mineral nutrition on immune competence in livestock has gained attention. Research supporting these efforts has focused on multiple areas of immunity, including both specific and non-specific branches of the immune system. The three trace elements, which have received the most attention include copper, selenium, and zinc. Chromium, which is not yet approved for use for cattle in the US, has also been investigated. This paper will focus on these elements.

Trace Mineral Requirements for Dairy Cattle
A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...

New Concepts in Trace Mineral Supplementation of Grazing Cattle Hydroxy Sources, Injectable Sources and Pasture Application
The trace mineral nutrition of grazing cattle is complicated by several factors among which are the impacts of trace mineral antagonists in grazed forage and the reliance on predictable, uniform intake of free-choice mineral supplements. Numerous options are available to assist in the management of trace mineral nutrition of grazing cattle. In recent years, significant research efforts have bee...
متن کاملEssential Trace Minerals for Grazing Cattle in Florida
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 ...
