The invention discloses a bio-
enzyme and
microorganism containing compound
feed additive and a preparation process thereof, which solve the problems of high production cost and less
viable count of beneficial microorganisms in the prior art. The bio-
enzyme and
microorganism containing compound
feed additive is characterized in that the additive is prepared by compounding a viable
organism preparation (prepared by carrying out liquid
fermentation and low-temperature
drying on
bacillus subtilis and brewer's
yeast) with an
enzyme preparation (prepared by carrying out
solid fermentation and
drying on
trichoderma reesei and
Aspergillus niger); and the
viable count of beneficial microorganisms in each
gram of the product is greater than 8*10<9> cfu / g, the
cellulase activity (refer to the quantity of
cellulose degraded by each
gram of the product per minute) is greater than 500 mg, the alpha-
amylase activity (refer to the quantity of
starch hydrolyzed by each
gram of the product per minute) is greater than 3000 mg, and the
protease activity (refer to the
mount of an
amino acid generated by caseins hydrolyzed by each gram of the product per minute) is greater than 400 mg. The bio-enzyme and
microorganism containing compound
feed additive disclosed by the invention has the advantages that: the feed
utilization rate of
livestock can be improved in a short term, the intestinal digestive
flora of
livestock is improved and balanced, the breeding cost is reduced, and the feed conversion rate and the
animal production performance are improved; and meanwhile, the additive is simple in preparation process, low in production cost, and suitable for industrialized production.
