Capital letters indicate statistically significant (p < 0.05) differences between control and other treatments by Dunnett tests; small letters indicate statistically significant (p < 0.05) differences between LPS group and the other treatments. 1 birds were fed the control diet and injected with LPS; 2 Standard error of the mean (n = 6 pens); 3 Initial body weight; 4 Final body weight; 5 Average daily gain; 6 average daily feed intake; 7 Feed conversion ratio.
