Compared with the control group, dietary supplementation with lactoferrampin-lactoferricin or chlortetracycline increased the body weight and daily weight gain and decreased the feed to gain ratio, diarrhea rate and serum IgM and IgG levels (p<0.05). The serum levels of IL-1β, IL-6, TNF-α, diamine oxidase and endothelin-1 were not significantly different among all treatment groups (p>0.05). Compared with the control group, dietary supplementation with lactoferrampin-lactoferricin changed the serum concentrations of 10 amino acids (p<0.05); dietary supplementation with chlortetracycline only changed the serum histidine concentration (p<0.05). These results indicate that lactoferrampin-lactoferricin and chlortetracycline have similar effects on piglets weaned at 21 days of age which is expected to have practical applications in the livestock industry.
