Embodiment 1

[0038] Embodiment 1: the preparation method of the rumen amylase of 100 units / g

[0039] Weigh 120 grams of 2000 units / g of α-amylase, add to 880 grams of lysine powder and mix, dry granulate in a dry granulator, dry at 70°C at low temperature to obtain dried granules; put 1000 100 grams of palm oil fat powder is heated to 100°C and melted as a packaging material; the dried granules containing amylase are fluidized in a fluidized bed, and the melted packaging material is cooled to 80°C and sprayed on the granules containing amylase On the surface, 100 units / g of ruminal amylase was obtained.

Embodiment 2

[0040] Embodiment 2: the preparation method of the rumen amylase of 400 units / g

[0041] Weigh 480 grams of 2000 units / g of α-amylase, add to 520 grams of lysine powder and mix, dry granulate in a dry granulator, dry at 70°C at low temperature to obtain dried granules; put 1000 100 grams of palm oil fat powder is heated to 100°C and melted as a packaging material; the dried granules containing amylase are fluidized in a fluidized bed, and the melted packaging material is cooled to 80°C and sprayed on the granules containing amylase On the surface, 400 units / g of rumen amylase was obtained.

Embodiment 3

[0042] Embodiment 3: the preparation method of the rumen amylase of 2000 units / g

[0043] Weigh 600 grams of 8000 units / g of α-amylase, add to 400 grams of lysine powder and mix, dry granulate in a dry granulator, and dry at 70°C at low temperature to obtain dried granules; The palm oil fat powder is heated to 100°C and melted as a packaging material; the dried granules containing amylase are fluidized in a fluidized bed, and the molten packaging material is cooled to 80°C and sprayed on the surface of the amylase-containing granules , that is, to obtain 2000 units / g of rumen-passing amylase.

Abstract

The invention discloses rumen bypass protecting amylase and a preparation method thereof. The rumen bypass protecting amylase is composed of two parts of a core material and a bag material; and the bag material is mainly prepared from any one or more of saturated fatty acid, acrylic resin IV or chitosan, the acrylic resin IV and the chitosan are not mixed, and the core material is mainly preparedfrom amylase. The preparation method comprises the steps that the amylase is subjected to dry granulating, and low-temperature drying and fluidified; and the surfaces of particles are coated with thesaturated fatty acid in a molten state, the acrylic resin IV dissolved in ethyl alcohol, or the chitosan dissolved in acetic acid, envelope is conducted, and the rumen bypass protecting amylase is prepared. According to the rumen bypass protecting amylase and the preparation method thereof, the amylase is not prone to being degraded in the rumen of ruminant animals, the rumen bypass ratio within four hours still reaches 90% or above, the rumen bypass protecting amylase can be effectively released when reaching the intestinal tract of the ruminant animals, undigested starch in the small intestine can be effectively digested, occurrence of ketosis, subclinical ketosis and fatty liver diseases is reduced, and the milk yield is increased.

Description

technical field [0001] The invention relates to the field of nutrients for ruminants, in particular to a rumen-passing protected amylase and a preparation method thereof. Background technique [0002] Starch is a high polymer formed by the condensation of many glucose molecules, which can be converted into glucose under the action of amylase. It is the main source of energy for dairy cows and the main source of glucose for dairy cows. Most of the starch is connected by α-1,4 glycosidic bonds, and a small amount is connected by α-1,6 glycosidic bonds. According to the molecular structure, it is divided into two types: amylose and amylopectin. Due to the fermentation of the rumen, ruminants have a fundamental difference in the digestion and utilization of starch from monogastric animals. After starch enters the rumen, it is first decomposed into volatile fatty acids (VFA) by rumen microorganisms, and the undecomposed starch enters the small intestine as ruminal starch (RES), ...
