2 Figure 1 Least squares means and standard errors for (a) total gram-negative bacteria, (b) environmental streptococci, and (c) coliform bacteria isolated from untreated sawdust (CON; white bars) or sawdust treated with a clay-based acidic bedding conditioner (ABC; black bars). Measurements were taken at d 0, 1, 2, 7, 14, and 21 over 2 periods. *P<0.05. Journal of Dairy Science  , DOI: ( /jds ) Copyright © 2013 American Dairy Science Association Terms and Conditions

3 Figure 2 Least squares means and standard errors for the pH of untreated sawdust (CON; white bars) or sawdust treated with a clay-based acidic bedding conditioner (ABC; black bars). Measurements were taken at d 0, 1, 2, 7, 14, and 21 during (a) period 1 and (b) period 2. *P<0.05.

4 Figure 3 Least squares means and standard errors for the bedding cleanliness of untreated sawdust (CON; white bars) or sawdust treated with a clay-based acidic bedding conditioner (ABC; black bars). Measurements were taken 3 times daily during (a) period 1 and (b) period 2. Cleanliness scores were on a 0 to 5 scale, where 0 = clean, 5 = extremely soiled.

5 Figure 4 Least squares means and standard errors for streptococci isolated from teat-end swabs of 16 lactating Holstein cows bedded on untreated sawdust (CON; white bars) or sawdust treated with a clay-based acidic bedding conditioner (ABC; black bars). Measurements were taken at d 0, 1, 2, 7, 14, and 21 during (a) period 1 and (b) period 2. *P<0.05.

6 Figure 5 Least squares means and standard errors for coliform bacteria isolated from teat-end swabs of 16 lactating Holstein cows bedded on untreated sawdust (CON; white bars) or sawdust treated with a clay-based acidic bedding conditioner (ABC; black bars). Measurements were taken at d 0, 1, 2, 7, 14, and 21 during (a) period 1 and (b) period 2. *P<0.05.
