Data represent means from 6 replicates per treatment
The P values represent the main effect of the diet, the main effect of LPS challenge and the interaction between the dietary treatments and LPS challenge
BWG Body weight gain, FI Feed intake; F/G feed intake consumed per unit of body weight gain; LPS (−) Dietary treatment were abdominal injections sterile saline (0.5 mg/kg body weigh); LPS (+) Dietary treatment were abdominal injections LPS (0.5 mg/kg body weigh). Control Basal diet; PCA1 Basal diet supplemented with 0.05 % PCA; PCA2 Basal diet supplemented with 0.075 % PCA; PCA3 Basal diet supplemented with 0.1 % PCA
