preparation example Construction

[0019] Its preparation method comprises the following steps:

[0020] After the components of the feed enzyme preparation are weighed according to the proportioning ratio, the components of the compound enzyme are firstly mixed, and then they are added together with the tea polyphenols and the carrier into the twin-shaft high-efficiency mixer for mixing. The mixing time is 10 minutes. The degree of mixing is tested on the finished product to ensure that the coefficient of variation is ≤5%.

Abstract

The invention provides a feed enzyme preparation capable of reducing diarrhea of weaned piglets. The feed enzyme preparation includes a complex enzyme, tea polyphenol and a carrier; the complex enzymeincludes 2,000 U / g of glucose oxidase, 3,000 U / g of amylase, 8,000 U / g of acid protease, 2,000 U / g of acid mannanase and 10,000 U / g of xylanase; and the carrier includes one or more of corn starch, mountain flour, medical stone or rice bran. A preparation method of the feed enzyme preparation includes the following steps: weighing each component of the complex enzyme preparation in proportion; uniformly mixing each component of the complex enzyme, and adding the tea polyphenol and the carrier into a double-shaft efficient mixer to mix, mixing time being 10-15 min; and performing mixing uniformity detection on a finished product after mixing, and ensuring that the coefficient of variation is less than or equal to 5%. The feed enzyme preparation can enhance the growing performance of weanedpiglets and reduce feed-meat ratio and diarrhea rate, and is an eco-friendly additive.

Description

technical field [0001] The invention belongs to the technical field of feed enzymes, and in particular relates to a feed enzyme preparation and a preparation method thereof. Background technique [0002] Piglet weaning is an important link in pig production. Due to weaning stress, piglets often suffer from diarrhea, which affects the growth performance of weaned piglets, and can even lead to death in severe cases. In production, high doses of zinc oxide are often added to feed to reduce the rate of diarrhea, but long-term use will cause side effects. [0003] In view of the above problems, research and development of a feed additive that can reduce diarrhea and increase weight gain of weaned piglets is of great significance for promoting the healthy development of the animal husbandry industry. Contents of the invention [0004] For the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a kind of feed enzyme preparation and pr...
