Summary and Implications
Fecal Analysis, off-test weights, and ultrasonic measurements were used to determine the response of BioplexTM trace minerals on the fecal mineral excretion (copper Cu, iron Fe, and zinc Zn) and growth and performance traits measured on live pigs (n=528). The use of BioplexTM mineral supplementation on phase fed growfinish pigs could potentially decrease the amount of heavy metal and nutrient excretion without impacting the overall performance of the animal. These organic mineral supplements can ultimately be fed to finishing swine without having a significant effect on percent lean (live or carcass), loin muscle area (LMA), backfat (BF10), average daily gain (ADG), or feed efficiency (FE). The use of BioplexTM trace minerals has the potential to reduce the environmental impact of swine production without any loss of production efficiency to the producer. Future work in the use of BioplexTM trace minerals and other mechanisms to reduce the environmental impact of swine production is warranted.
