An update on alternatives to antimicrobial growth promoters for broilers

An update on alternatives to antimicrobial growth promoters for broilers.

Livestock performance and feed efficiency are closely interrelated with the qualitative and quantitative microbial load of the animal gut, the morphological structure of the intestinal wall and the activity of the immune system. Antimicrobial growth promoters have made a tremendous contribution to profitability in intensive husbandry, but as a consequence of the increasing concern about the pot...

Alternatives to Growth Promoters

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 ...

General Commentary on: Alternatives to Antibiotic Growth Promoters in Animals

Recent studies have evaluated the impact of alternatives to antibiotic growth promoters (AGPs) such as phytogenic feed additives (PFAs) in vitro and in vivo. Zhou and colleagues studied the antibacterial properties of 30 herbs on pathogenic Gram-negative and positive bacteria (1). Thirteen of the 30 herbs exerted a significant effect against Escherichia coli ATCC 25922 (p < 0.01, n = 11 and p <...
