Feed additive and preparation method and application thereof

Abstract

The invention belongs to the field of feed additives and particularly relates to a feed additive and a preparation method and application thereof. The feed additive provided by the invention is prepared from the following raw materials in percentage by weight: 30% to 40% of artemisia powder, 20% to 35% of dunaliella salina powder, 15% to 20% of plant extract and 15% to 25% of bioactive peptide microcapsules, wherein the plant extract is prepared from the raw materials: oregano, cinnamomum cassia and black plum, each bioactive peptide microcapsule is prepared from a capsule core and a capsule wall material which are in the weight ratio of (0.2 to 0.6) to 1, each capsule core is prepared from casein phosphopeptide and antibacterial peptide which are in the weight ratio of (1 to 4) to (0.5 to 2), and each capsule wall material is prepared from chitosan and sodium alginate which are in the weight ratio of 1 to (4 to 6). The feed additive provided by the invention can be used for promoting the growth of animals, increasing efficiency of feed utilization, enhancing the immunity of the animals, lowering disease infection rate and effectively preventing and treating diseases of livestock and poultry, is stable in quality, can be stored in long term and is not prone to mildewing.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive and its preparation method and application. Background technique [0002] With the rapid development of my country's animal husbandry industry, people's demand for animal products has shifted from the initial quantity demand to the demand for quality and safety. Residues of harmful substances in livestock products are the main problem affecting the safety of livestock products, and feed additives are one of the main factors causing the residues of harmful substances to exceed the standard. [0003] As an important raw material in animal husbandry, feed additives play an important role in inventions such as animal production performance, enhancement of disease resistance, improvement of feed utilization efficiency, improvement of animal product quality and economic benefits. However, there are many problems in the current use of feed additives. First, feed additives ...

Problems solved by technology

However, there are many problems in the current use of feed additives. First, feed additives are prone to mold and deterioration, and cannot effectively preserve the biologically active ingredients contained in them, especially the ingredients such as probiotics and feed enzymes; secondly, Some feed additives are poorly absorbed in animals, especially additives containing biologically active ingredients, which are easily inactivated after being hydrolyzed by pepsin in the body; finally, feed additives are often used in excessive amounts, beyond the range, and beyond the time limit. Drug-resistant pathogenic bacteria and mutated pathogenic bacteria in the body continue to occur, animal immunity is reduced, and the disease is prone to complex and changeable diseases, and the breeding environment deteriorates, eventually causing a series of food safety problems

[0004] Ai Mo is the powder obtained by crushing the mesophyll, petiole, leaf veins and other substances that remove the hairy mesophyll, petiole, and leaf veins during the preparation of moxa leaves. Ai Mo has the general medicinal value of Ai Ye, and has the functions of warming the meridians to stop bleeding, dispelling cold and relieving pain, relieving cough and asthma, It has anti-leakage, anti-pregnancy, damp-damp and antipruritic effects. Although Artemisia argyi has been widely used in livestock and poultry feed additives, there are few reports on the application of moxa mossies in livestock and poultry feed additives.
