Trace Mineral Nutrition Symposium: Exploring recent developments in swine and ruminants.

Trace Mineral Nutrition of Ruminants on Forage Based Systems

Salt Institute Newsletter (STM) First Quarter 2014 TRACE MINERALS AND REPRODUCTION IN RUMINANTS

INTRODUCTION Reproductive efficiency is a major factor that affects profitability in ruminants. The reproductive process consists of the male producing viable sperm, the female exhibiting estrus and conceiving, and proper embryonic and fetal development that results in the birth of a live offspring. A number of trace minerals are important in maximizing reproductive performance. Even marginal t...

Bioavailability and Antagonists of Trace Minerals in Ruminant Metabolism

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...

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...

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...
