Additionally, results of the studies on humans and mice indicated that chitosan inhibited oral streptococci,13 reduced early preneoplastic markers of colon carcinogenesis,14 and stimulated mucosal and systemic antibody responses against Bordetella pertussis filamentous haemagglutinin and recombinant pertussis
Our recent studies with the same birds as in this study showed that dietary supplementation of oligochitosan (COS) increased the ileal digestibility of nutrient and improved performance in broilers.
