W0, Initial body weight before injection of LPS; W1, Body weight gain 2 days after the first injection of LPS; W2, Body weight gain 2 days after the second injection of LPS; W3, Body weight gain 2 days after the third injection of LPS

a,b In the same column, values with the same or no letter superscripts mean no significant difference (P > 0.05), while with different letter superscripts mean significant difference (P < 0.05)
