•Small intestinal bacteria havesimilar aminoacid requirements as the host.•Lactic acid bacteria and the host compete for dietary amino acids.•Protein escaping ileum is subject to putrefaction in the caecum.•Putrefaction produces toxin metabolites such as amines, indoles and ammonia.•Feed enzymes pot...
