Abstract
Two methods of preparing cows for milking were compared. One preparation consisted of wiping each teat clean with individual, premoistened, disposable wipes. This method was compared with washing teats with a hand-held water nozzle and drying with individual paper towels. Two groups of eight Holstein cows each were randomly assigned to the two treatments. Aseptically collected weigh jar milk samples from individual cow milkings were analyzed for standard plate count, preliminary incubation count, laboratory pasteurization count, and coliform count. Pretrial bacterial counts were monitored for 2 d and were used as covariates in statistical analyses. Cows were sampled for 7 d followed by a 2-d rest after which treatments were switched and cows sampled for another week. Method of udder preparation did not affect daily milk production, fat or protein percent. Standard plate counts and preliminary incubation counts were significantly lower for wipe treatment (363 vs 933 CFU/ml and 263 vs 661 CFU/ml). There was no treatment difference for laboratory pasteurization count or coliform count. Raw milk quality as determined by standard plate count and preliminary incubation count was improved by the wipe treatment.
