Two farms (farms A and B) had United Kingdom-registered organic status and adhered to the United Kingdom Advisory Committee on Organic Standards. Under these standards, no animal or group of animals can receive more than three courses of treatment with a veterinary medicinal product or antimicrobial agent within 1 year. Two cohorts were monitored on a farm for three farms (farms A, B, and D). One cohort was monitored on farm C. Only one cohort per year was monitored per farm. Cohorts were of unequal size (10 to 46 calves) and were studied for different lengths of time (4 to 8 months) due to differing management strategies on the farms. Calves were born at different times of the year on the four farms and were kept with their dams as single groups, either at pasture or in straw-bedded barns, according to the season. The calves in this study were born into suckler herds and were therefore able to suckle their dams at will throughout the study period.
Individual rectal fecal samples were collected from cohort calves within the first month after birth and then at monthly intervals for up to eight sampling months. Fecal samples were also collected individually from all cattle in the herd (1 year old or older) either before or during the sampling period of each calf cohort.
