A compound feed additive and a preparation method thereof

Abstract

The present invention discloses a Chinese herbal compound feed additive, and belongs to the technical field of feed additives. The feed additive consists of the following raw materials in parts by weight: shiitake fruiting body powder 3-6 parts, crushed isatis roots 3-6 parts, crushed radix asparagi 6-10 parts, aspergillus niger culture 10-25 parts and liquorice powder 1-2 parts. The feed additive contains Chinese herbal ingredients, and the Chinese herbal ingredients are mixed with the aspergillus niger culture containing a lot of bacteria and cellulase which can promote the cell wall dissolution of Chinese herbal plants in the body's digestive process, dissolving more plant cell contents, degrading macromolecules not prone to digestion including polysaccharides, proteins and lipids into small molecule substances which are conducive to gastrointestinal digestion and absorption of pigs, so that the absorption rate of beneficial ingredients in Chinese herbal medicines increases by 26% in the pigs in vivo, the effectiveness of the feed additive in preventing and treating pig respiratory diseases is effectively improved, the anti-virus ability and auto immunity of the pigs are enhanced, the health state of the pigs is improved, and the growth of the pigs is promoted.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a Chinese herbal medicine compound feed additive. Background technique [0002] The occurrence of porcine respiratory disease syndrome is usually caused by multiple factors, and its pathogenic causes mainly include: 1. Primary pathogen: often several pathogens exist at the same time, such as porcine reproductive and respiratory syndrome virus, commonly known as "PRRS ", Mycoplasma pneumoniae, porcine circovirus type II, pseudorabies virus, swine influenza virus, Actinobacillus pleuropneumoniae, etc.; 2. Secondary pathogens: After pigs are infected with primary pathogens, due to resistance and immunity The common secondary pathogens are: Streptococcus suis, Haemophilus parasuis, Pasteurella multocida, Toxoplasma, Eperythrozoon, classical swine fever virus and other related respiratory symptoms; 3. Adverse Environmental conditions, such as too much stocking density, poor ve...

Adverse environmental conditions, such as too much stocking density, poor ventilation in the house

[0003] At present, antibiotics are commonly used for treatment, which is easy to produce drug resistance. The abuse of antibiotics leads to the emergence of "super bacteria", the aggravation of mycotoxin hazards, the pollution of the breeding environment, and the lack of attention to the establishment of a biosafety system, etc.
