It is intended to provide a process for producing a composition containing beta-1,4-mannobiose which can inhibit the fixation of salmonella in animal bodies and effectively discharge the salmonella therefrom; a feed additive comprising the composition containing beta-1,4-mannobiose; and a feed comprising the composition containing beta-1,4-mannobiose. Namely, a process for producing a composition containing beta-1,4-mannobiose characterized by comprising treating a natural material containing mannan with a mannan digesting enzyme and thus forming at least 10% by weight, based on the mannan before the digestion, of beta-1,4-mannobiose; a composition containing beta-1,4-mannobiose characterized by being obtained by treating a natural material containing mannan with a mannan digesting enzyme and containing at least 10% by weight, in terms of dry matter, of beta-1,4-mannobiose; a feed additive comprising the composition containing beta-1,4-mannobiose; and a feed comprising the composition containing beta-1,4-mannobiose. |
