Many trials have demonstrated that the higher bioavailability of MINTREX Zn allows producers to meet the nutritional requirement of the animal with reduced levels of inclusion. Metallothionein (MT) is a well-accepted biomarker for zinc bioavailability. The following experiment measured the MT expression in the small intestine of broilers when fed different zinc sources. Data shows that MINTREX Zn is the most bioavailable trace mineral (Figure 1).
Improved HeathZinc plays a significant role in immune system development and response. Animals fed MINTREX Zn show a more robust production of antibodies when challenged with a commercial coccidiosis vaccine than other sources of zinc (Figure 2).
Better bioavailability with MINTREX trace minerals can also result in structural benefits. A trial with broilers compared inorganic trace minerals at higher levels vs. MINTREX chelated trace minerals at lower levels. The birds supplemented with MINTREX showed significant improvements in structural integrity of tissue, as measured by reduced footpad lesions relative to the control (Figure 3). Footpads were graded on a five point scale with a score of one being best and five being worst.
In another trial with turkeys, MINTREX Cu, Mn and Zn, were added to the normal inorganic trace mineral program or partially replaced the inorganic trace minerals. The addition of MINTREX chelated minerals significantly increased both tibia breaking strength and tibia bone thickness (Figure 4).
Feeding animals the best and most effective source of zinc is important so that animals can fully utilize the trace mineral. With MINTREX Zn, producers can maintain excellent performance while feeding less and still improve the structural health of the animal.
