PURPOSE:To obtain the titled additive, containing a blend of three kinds of microorganisms consisting of a proteolytic enzyme, fat hydrolyzing enzyme, saccharifying microorganism, lactic acid bacteria and butyric acid bacteria as an active ingredient and capable of accelerating digestion and absorption of proteins and lipids in a feed, improving productivity in culture of fishes and providing a feed having excellent feed efficiency as well as body weight increasing rate. CONSTITUTION:The titled additive obtained by blending 1pt. lactic acid bacteria, e.g. Streptococcus faecalis, etc., with 1-8pts. saccharifying microorganism, e.g. Bacillius subtilis, etc., butyric acid bacteria, e.g. Clostridium butyricum, etc., to provide (C) a blend of the three kind of microorganisms capable of exhibiting excellent symbiotic phenomenon in living bodies and blending (A) a proteolytic enzyme, e.g. protease, etc., (B) a fat hydrolyzing enzyme produced by a microorganism of the genus, e.g. Rhizopus or Candida, the component (C) and, if necessary, (D) a nutritent enriching component, e.g. yeast, gluten meal, rice bran oil cake, corn starch, etc. The resultant additive in an amount of 0.1-5.0% based on a feed is added thereto for use. |
