Comparison of Grain Sources (Barley, White Corn, and Yellow Corn) for Swine Diets and Their Effect on Production and Carcass Traits

Energy sources differ in content, quality, and availability of nutrients. The objective of this study was to identify and compare differences in production and carcass traits in pigs fed different energy sources. While pigs fed a barley-based diet had a smaller loin muscle area, there was no difference among diets when comparing fat depth or percent fat-free lean. Barley based-diets and a diet containing one-third yellow corn and two-thirds white corn had a lower lean gain per day on test. There was no significant difference in average daily gain or feed-to-gain ratios

Growth Comparison and Fecal Mineral Excretion of Inorganic and Organic Trace Mineral Supplementation in Swine

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
