Table 4 Descriptive statistics for the standard plate count between two points

Milk collection points	N	MIN	Max	Mean[±S.E] log10 cfu/ml	Log10 increment	Df	95% CI for mean		P-value
							lower	upper
Directly from teat	60	2.079	6.407	4.5907 [0.117]	0.18 [0.23]	1	4.352	4.832	0.011

Total numbers of samples (N); maximum count (MAX) vs. minimum (MIN) log10 cfu/ml plate counts
Mean [±S.E] log10 cfu/ml = log 10 of colony-forming unit (CFU) above or below standard error (±S.E) in one millilitre of milk sample
Df degree of freedom, I confidence interval
