Feed additives enhancing immune responses in poultry

摘要

The aim of the article was to present the results of experiments on the effects of feed additives on immune processes in poultry. Based on data taken from literature it could be concluded that pre- and probiotics, mannano-oligosaccharides, ss-glucan and nukleotides from baker's yeast cells and some herb extracts (Echinacea, Aloe and Ginseng) are particularly effective immunomodulators. The use of these feed additives may enhance immune responses and resistance to pathogen microorganisms in poultry.
