Reference


Seventy-two lots of cattle were sampled. Samples were obtained during monthly visits to a commercial beef processing plant from February 2014 to January 2015. The goal each month was to obtain 60 fecal samples: 10 from each of three lots of RWA cattle and 10 from each of three lots of CONV cattle. A lot was defined as a group of cattle from a production site that were harvested together. For each month, the six lots represented six different production sites. Overall, 359 and 360 fecal samples were obtained from RWA and CONV cattle, respectively

Feces were recovered from the colons of 10animals/lot for 36 lots of CONV cattle and 36 lots of RWA cattle over a 12-month period. Feces were recovered from colons to avoid cross-contamination associated with harvest.. Samples were pooled by lot.
