متن کاملComparison of bacteria populations in clean and recycled sand used for bedding in dairy facilities.
Bedding samples were collected twice from commercial dairy free-stall facilities that used recycled sand and clean sand in both the summer and winter. Collection began on the day sand was taken from the pile (d 0) and placed in the free stalls, and continued for 5 to 7 additional days.
