Pigs were fed ad libitum a 14,1 crude protein diet containing barley, wheat, wheat bran, extracted soybean meal and a feed supplement. Peptides rather than amino acids were the primary component of the TCA-soluble ninhydrin-reactive material in the caecum. Fermentation of mucin yielded more volatile fatty acid than fermentation of other nitrogenous substrates. Low proportions of branched-chain VFA were also in VFA produced from mucin and RNA. It can be concluded, therefore, that caecal microorganism convert nitrogenous substrates, which would be lost in faeces, into valuable products, utilizable by the host.
