Pre-trial production performance and the baseline level of LPS in plasma and feces
No significant differences (p>0.05) in pre-trial (d 0) milk yield, DMI, and LPS levels in plasma and feces between control and SC were noted on both farms (Table 2). Milk yield and DMI ranged between 19.6 and 21.7 kg/d, and 18.9 and 19.2 kg/d, respectively. Plasma LPS levels ranged from 0.15 to 0.46 EU/ml. Fecal LPS ranged from 6,668 to 7,984 EU/ml.
