The invention provides a feed enzyme preparation for reducing diarrhea of weaned piglets. The feed enzyme preparation comprises a compound enzyme, tea polyphenols and a carrier, and the compound enzyme comprises 2000U/g glucose oxidase, 3000U/g amylase, 8000U /g acid protease, 2000U/g acid mannanase and 10000U/g xylanase, and the carrier includes one or more of corn starch, stone powder, medical stone or rice bran. The preparation method includes the following steps: after each component of the composite enzyme preparation is weighed according to the proportion, firstly mix the components of the composite enzyme, and then add the tea polyphenols and the carrier together into a double-shaft high-efficiency mixer to mix and mix. The time is 10min-15min. After mixing, the mixing degree of the finished product is tested to ensure that the coefficient of variation is less than or equal to 5%. The invention has the advantages of improving the growth performance of weaned piglets, reducing the feed-to-meat ratio and diarrhea rate, and the feed enzyme preparation of the invention is a green environmental protection additive. |
