IOWA CITY, Iowa (AP) — Iowa Board of Regents President Bruce Rastetter says a study by Iowa State University on cattle performance at one of his confinements will be beneficial to all beef producers.

ISU researchers have been working with Rastetter's company, Summit Farms LLC, since 2011 to study whether cattle grow bigger and healthier with less feed when they stand on rubber mats instead of concrete slats.

Preliminary findings published last year suggested the mats may be beneficial but were inconclusive, and more detailed data are expected to be available in coming months.

Its general manager says Summit Farms is waiting for the findings before deciding whether to install more rubber mats for the 8,000 cattle that it feeds.

Rastetter says the results will be made public, helping all producers make similar decisions.
