CN = without experimental C. jejuni infection; CP = with experimental C. jejuni infection; SP diet = standard protein diet; LP diet = low protein diet; WFR = water-feed ratio in kg water intake/kg diet intake as fed; FCR = feed conversion ratio in kg diet intake as fed/kg body weight gain; CPE = crude protein efficiency in kg body weight gain/kg crude protein intake; AAGL = sum growth limiting” amino acids like arginine, isoleucine, lysine, methionine, threonine, and valine; AACM = sum of amino acids C. jejuni metabolizable like aspartic acid, glutamic acid, proline, and serine.
