The effect of complexed trace minerals on semen quality

摘要

Ration formulation is becoming more sophisticated as we attempt to balance rations to support higher and higher levels of production. Much emphasis is placed on balancing the protein, carbohydrate fiber and fat fractions of the diet. However, less attention has focused on the mineral specifications, especially the trace mineral fraction. Trace minerals play a key role in many enzyme systems and consequently have a significant impact on swine performance. The objective of this paper is to review the function of trace minerals in swine production and to describe the use of trace mineral complexes to enhance sperm output.
