Alternatives to Growth-promoting Antibiotics Spreadsheet

The Checkoff’s animal science committee recognizes many producers are seeking alternatives to maintaining pig performance following removal of growth-promoting antibiotics. While there are many commercially available products purported to enhance growth, many of these products lack consistency in demonstrating beneficial results. This spreadsheet is the result of project #15-204 that was completed by Nick Gabler and Wes Schweer of Iowa State University. It can be downloaded and then searched for a variety of terms to isolate references to scientific articles that incorporated those terms. For example, searching for “copper” will result in articles that had “copper” as one of the dietary treatments. The use of this spreadsheet can help producers identify compounds that my serve as suitable alternatives to growth-promoting antibiotics.

Animal Science Webinar Series

The Animal Science Research Webinar Series is designed to highlight results from completed research projects funded by the Animal Science Committee of the National Pork Board.
These results have direct application to production and therefore pork producers will find this information to be valuable as they make management decisions that affect productivity and profitability. The webinar will be presented by the principle investigator from each project and webinar participants will have the opportunity to interact with the investigator following the presentation.

Pork Industry Productivity Analysis

The National Pork Board Animal Science Committee recognized that there is a lack of publicly available information for producers to use when benchmarking productivity in various phases of production.

Therefore, they initiated the Industry Productivity Analysis with the purpose of providing data documenting the productivity of U.S. pork production. The information mined from analysis of this data is intended to benefit all producers through improved productivity at the farm level and will serve to inform the Checkoff programs, academics and other funding agencies about areas of research which are likely to have the greatest impact.
