Six dairy farms located in the San Joaquin Valley in California were identified and enrolled in the study as a convenience sample described in a previous study. Cull cows were identified for fecal sampling once during each season between 2015-2016. The choice of week to sample cull cows during any of the four seaosns was by convenience. From the list of cows selected by the diary farms for culling, 10 cows were randomly selected for fecal sampling on the day of their removal from the herd using a random number generator.
Fecal samples were manually collected from the rectum of randomly selected cows.
