Summary:
Synthetic porcine beta-defensin-2 (pBD-2) was tested as an alternative to antimicrobial growth-promoters in pig production. Thirty 21-day weaned piglets were challenged with Escherichia coli, and orally dosed with either sterile water (CON), pBD-2 (BD) or neomycin sulphate (NS) twice daily for 21 days. Therefore, pBD-2 has antimicrobial activity in piglets, and it can improve growth performance, reduce inflammatory cytokine expression and affect intestinal morphological indices in the same way as probiotics. Moreover, pBD-2 has a more positive effect on intestinal morphological indices and intestinal probiotics of piglets than does NS. Therefore, the present results suggest that pBD-2 may be a suitable replacement for NS in piglets.
