Alternatives to Growth Promoters
نویسنده
چکیده
In pig production, the terms "growth promoter", "performance enhancer", and "digestive enhancer" include a diverse range of products ranging from simple chemicals (copper salts) to chemically produced antibacterial compounds (carbadox) to antibiotics (tylosin, avilamycin, salinomycin, virginiamycin). Most of the antibiotic group are produced during a fermentation process by yeasts, moulds, and other microorganisms and have been used in pig production for over 40 years. Newer "performance enhancer" products include probiotics, enzymes, metal chelates, bacterial cultures, and complex sugars.
