1. Introduction In-feed supplementation of antibiotics was firstly reported to promote growth in chickens (Moore et al., 1946) and subsequently in pigs (Jukes et al., 1950; Luecke et al., 1950). Since then, antibiotics have been routinely used in livestock production at subtherapeutic levels for disease prevention and growth promotion and are more commonly known as antibiotic growth promoters (Di...

I'm very interested in this article due to my 40 years of experience in Thai Livestock production, which tries to avoid using Antibiotics in animal farming. The good management practices and the ABO alternatives are most concerned. I would like to collect more information and learn more to educate and advise our customers.
