The invention discloses a neutral protease-containing growing pig dedicated enzyme and a preparation method thereof and belongs to the technical field of zymin preparation. The neutral protease-containing growing pig dedicated enzyme is scientifically compounded from bacillus subtilis culture, acidic xylanase, acid protease, phytase, beta-dextranase, cellulase, amylase, beta-mannase, pectinase, Chinese herb extracts, a protective agent and an activating agent. The bacillus subtilis culture can improve immunity of the animal organism, promote development of immune organs and maturity of intestinal structures and functions of animals, and increase daily gain of animals and improve feed conversion ratio. The neutral protease-containing growing pig dedicated enzyme provides a safe digestive enzyme for livestock, effectively relieves digestion burden, increases the utilization rate of raw materials and the growth rate and protects the environment. In addition, appropriate amount of activating agent can fully play the efficiency of a zymin under the same condition and saves the additive amount of the zymin; the Chinese herb extracts are scientifically compounded to prolong the expiration date of a composite zymin and improve the immunity of livestock. |
