BIO-ACTIVE FEED INGREDIENTS
- Antibiotics
- In order to fully understand the importance of pronutrients, the use and relevance of antibiotics in animal feeds should first be considered, as many nutricines have been developed to replace these compounds. Antibiotics are chemical compounds, which in small quantities are harmful to other organisms. They occur widely in nature but the term is generally restricted to compounds which are microbial in origin, particularly those used to control other harmful micro-organisms, generally bacteria.

The knowledge of the gastrointestinal microflora has substantially improved since 1994 and new methods for studying the microflora have been developed. There is now considerable emphasis on the use of alternatives to antibiotic growth promoters in animal production. This includes discussions of enzymes, oligosaccharides, probiotics and organic acids. This revised volume gives a modern understanding of the microflora in the gastrointestinal tract and indicates how this can be managed in modern animal production without the reliance upon antibiotic growth promoters.
