Antimicrobial compounds have been commonly used as feed additives for domestic animals to reduce infection and promote growth. Recent concerns have suggested such feeding practices may result in increased microbial resistance to antibiotics, which can have an impact on human health. As part of our research project we have been studying the commensal microbial …
The most critical issue facing livestock and other small family operations nationwide is the development and implementation of cost effective pollution prevention technology. Our livestock producers, especially swine, continue to seek a best management practice (BMP) that is effective, economical, and practical, and in compliance with new US EPA laws. The Department of …
