Abstract

The objective of this study was to observe relationships among somatic cell count (SCC) and bacteria counts in milk, on teat ends of lactating cows, and in compost samples from the aerated layer of the compost bedded pack. Twenty-nine lactating cows were used in this study. Clinically mastitis cows were not selected for the trial. The correlation between total bacteria count (TBC) and Streptococcus spp. of teat end and hygiene score was (r = 0.49) and (0.44, P = 0.01), respectively. In addition, there was a positive correlation (0.40, P = 0.03) between TBC on teat ends and somatic cell score. When analysing bacterial populations on teat ends and in milk, there was a positive correlation (0.39, P = 0.03) between Escherichia coli at the teat end and coliform counts in milk and also a positive correlation (0.38, P = 0.04) between coliform counts at the teat end and milk. Furthermore, Streptococcus spp. counts on teat end were positively correlated (0.38, P = 0.04) with TBC in milk. Although correlations were observed between hygiene score and SCC with bacterial population, all correlations were moderate. Therefore, hygiene score was not an efficient tool to estimate bacterial populations on teat end and milk.
