Purple pennisetum purpureum feed particle additive and preparation method and application thereof

Abstract

The invention relates to the technical field of feed molds and feed processing, in particular to a purple pennisetum purpureum feed particle additive and a preparation method and application thereof. The purple pennisetum purpureum feed particle additive comprises an active ingredient core body, a permeation layer, and a gastric soluble layer, wherein the active ingredient core body is the inner core, the core body is covered with the permeation layer, and the permeation layer is covered with the gastric soluble layer; besides, a plurality of drainage holes are formed in the permeation layer, the drainage holes penetrate through the permeation layer, and the pore diameter of the parts, at the end of the gastric soluble layer, of the drainage holes is 3-4 times the diameter of the parts, at the end of the core body, of the drainage holes. Due to the structure of the purple pennisetum purpureum feed particle additive, the release ability of active ingredients and the shelf life of the additive can be effectively improved. The active ingredients of the feed additive comprise fermented pennisetum purpureum, fermented radix puerariae, aloe polysaccharides, and an amino acid chelating solution. By use of the additive, the dissolution rate of the gastric soluble layer in the gastric juice of a buffalo can be effectively increased, and the palatability, tenderness and flavor of the beef can be improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of feed processing, in particular to a purple elephant grass feed granule additive and a preparation method and application thereof. [0003] 【Background technique】 [0004] Elephant grass (Pennisetum purpureum) is a perennial herbaceous plant belonging to the grass family Pennisetum genus, with erect stems, clusters, many tillers, large leaves, soft texture, and not strict requirements on the soil. It is a herbivore for raising cattle and sheep in southern my country Commonly grown grass grass. The purple elephant grass of this application is not an ordinary species of elephant grass, but was introduced and cultivated by animal husbandry research in Guangxi Zhuang Autonomous Region. In 2014, it was approved and registered as a new national forage grass variety. It has tall plants, high yield, rich nutrition, and rich in anthocyanins Vegetable, soft and juicy, with large leaves, good palatability and...

Problems solved by technology

Using elephant grass as a feed additive will greatly improve the utilization rate of active substances in elephant grass. Currently, the feed additives on the market include paste, powder and granular feed. From the perspective of storage and transportation, powder and granular feed are more convenient for transportation and storage. However, if active substances are added to feed additives: such as live probiotics, since probiotics are mostly anaerobic microorganisms, they cannot survive in the air for a long time. If it is necessary to ensure that the live bacteria can act on the animal body, how to preserve the live bacteria It is the technical problem that feed pellets need to solve; the stomach of ruminants is divided into compound stomach, sub-rumen, reticulum, omasum and abomasum; the mucosa of the first three chambers has no glands, and is mainly used for food storage, fermentation, and fiber decomposition and only the fourth gastric chamber has gastric juice, if the active substance can be transported through the first three stomachs to the fourth stomach, and decomposed rapidly at the same time, it is a technical problem that has not been studied in the field of feed
