(1) α- amylase can increase feed conversion ratio and improve production performance.
(2) α- amylase can effectively decompose resistant starch which produces feed raw material itself and in the process of machining, improving energy utilization rate.
(1)High tolerance to animal acid gastrointestinal environment.
pH range: valid pH range is 2.0~7.0; the optimum pH is 5.0.
(2) Heat-resistant is good.
Heat-treatment for 10min in different temperature at pH6.0
One unit of amylase activity (U) is defined as 1g solid enzyme(or 1ml liquid enzyme)，liquefies 1mg soluble starch at 60℃ and pH6.0 in 1min.
Recommended dosage in complete feed of α- amylase with 7000 U/g:80-100g/t.Add to premixed feed and concentrated feed in proportion.
