Values are the mean ± SEM, n = 6 per treatment (the n = 6 refers to the number of pigs slaughtered and sampled). a,b,c Mean values sharing different superscripts within a row differ (p < 0.05). NP = normal protein basal diet no antibiotics included; NC = low-protein basal diet no antibiotics included; PC = low-protein basal diet + antibiotics (75 mg/kg quinocetone, 20 mg/kg virginiamycin and 50 mg/kg aureomycin); MCT = low-protein basal diet + 2 kg/T tricaprylin/tricaprin; GML = low-protein basal diet + 2 kg/T glycerol monolaurate.
