Abstract

The invention discloses a novel feed additive for broilers, which comprises the following additive materials in percentage by weight: 10 to 25 percent of astragalus extract, 5 to 25 percent of ginseng extract, 5 to 20 percent of Siberian ginseng P.E, 15 to 35 percent of mannase and 10 to 35 percent of xylanase. The addition of complete feed added into every 999 kilograms of broilers is 1 kilogram. The additive is rich in bioactive substances and enzyme preparations, has antibacterial activity and antiviral activity, can replace antibiotics to improve the digestion utilization rate of feed for the broilers, has the effects of stimulating appetite, preventing diseases, promoting the growth of the broilers, increasing the utilization rate of the feed, improving the immunity of organisms and improving the quality of meat, and is an environmentally-friendly and safe feed additive without toxic or side effect and medicinal residues.

Description

A kind of novel broiler fodder additive

Technical field

The invention belongs to the animal feed manufacture field, more specifically relate to the broiler fodder additive.

Background technology

Feeding of broiler is the industry that develops rapidly over nearly 20 years, for efficiency of feed utilization is grown, improved to prevent disease, promotion fryer fast, in perfect compound feed, add nutritive additives such as vitamin, trace element, amino acid, also add non-nutritive additives such as antibiotic, mould inhibitor, flavor enhancement.The antibiotic medicine that adds in the feed can cause drug resistance strain generation, fryer to produce drug resistance, bring a difficult problem for the control of disease; It is healthy that problems such as while medicament residue also can influence people.Along with the raising of people's living standard and to the attention of food security, the antibiotic-free feed Study on Additive has become popular research topic.

Fryer drug resistance and medicament residue problem and raising efficiency of feed utilization problem, the nutritionist has done a large amount of research work both at home and abroad, many solutions and method have been proposed, in broiler fodder, ban use of antibiotic to solve the medicament residue problem as some national regulations of Europe, add probiotic, enzyme preparation etc. to improve efficiency of feed utilization, obtained effect in various degree.Therefore alternative antibiotic solution fryer medicament residue problem of development of new feed addictive and efficiency of feed utilization problem are the problems that needs to be resolved hurrily at present.Plant extracts is to utilize advanced technology and process equipment to extract and refining bioactivator in the middle of plant, the discovery of bioactivator be the nineties in 20th century nutrition study one of great achievement, this class material have antibacterium, antiviral, antitumor, anti parasitic is active, have anti-oxidant, improve immunity, reduce effects such as blood sugar, blood fat.Mannase, zytase are the enzyme preparations of utilizing microbial fermentation to produce, can improve the digestive utilization ratio of cellulose in the feed etc.Novel broiler fodder additive of the present invention is to utilize plant extracts, mannase, zytase, promptly promote fryer to grow, improve efficiency of feed utilization fast, improve immunity, solved fryer drug resistance and medicament residue problem that antibiotic medicine exists again.

Summary of the invention

The purpose of this invention is to provide a kind of feed addictive of forming by Astragalus Root P.E, ginseng extract, siberian Ginseng P.E, mannase, zytase, can promote appetite, raising efficiency of feed utilization, the promotion growth of meat chicken of fryer, improve fryer immunologic function, prevent disease, improve meat, improve commodity value.It is a kind of green safety feed addictive that harmful components are residual, environment do not had any pollution that has no side effect, do not have.For achieving the above object, the present invention adopts following technical measures, according to plant extracts can activating immune system, promote lymphocyte transformation and propagation, antibacterium, antiviral, promote RNA, DNA, protein synthetic etc., can improve animal immunizing power, promote growth of animal, reduce the death rate.Mannase, zytase can reduce enteron aisle chyme viscosity, destroy the plant cell wall construction, eliminate its anti-oxidant action, generate a large amount of functional oligosaccharide (xylobiose, xylotriose), improve intestinal microflora, help fryer health, the material that has additional nutrients absorbs, and reduces the ight soil discharging.It adds materials and weight ratio is: Astragalus Root P.E 10-25%, ginseng extract 5-25%, siberian Ginseng P.E 5-20%, mannase 15-35%, zytase 10-35%.Above-mentioned material weighed on request put into mixer again, mix, with the composite feed additive pack that mixes, seal.
