Abstract

The invention discloses an antimicrobial-free feed formula for weaned pigs. The antimicrobial-free feed formula consists of puffed corn, fermented bean pulp, soybean, soybean oil, fish meal, whey powder, a piglet premix, a plant extract additive, a coating acidifier, microecologics and a complex enzyme preparation. The antimicrobial-free feed formula fully makes use of the physiological characteristics of the weaned pigs and can solve the problems of incomplete immunologic functions, low disease-resistance capability, insufficient digestion secretase, incomplete intestine development, low digestion and absorption capability, high risk of diarrhea and the like of the weaned pigs, thus fulfilling the aim of increasing the daily growing weight; moreover, the antimicrobial-free feed can thoroughly replace conventional antibiotics and zinc oxide; the digestion utilization rate of the feed is improved, the health of the intestinal tracts of the piglets is guaranteed, and the antimicrobial-free feed is an ideal feed for the weaned pigs.

Description

A kind of weanling pig nonreactive feed formula
Technical field
What the present invention relates to is the formula of piglet feed field, is specifically related to a kind of weanling pig nonreactive feed formula.
Background technology
Weanling pig has the characteristics such as fast, self the endogenous enzymes hyposecretion of growing, immune system imperfection.The environment that wean brings in addition and the change of feed, slightly have mismanagement, very easily produces the situation of diarrhoea.In order to control diarrhoea, directed toward bacteria property diarrhoea, used high dose zinc oxide, copper sulphate, high dose antibiotic, and the consequence of bringing is that not have in a large number the zinc of absorption and copper bar to be put into external, contaminated environment; Piglet is used the antibiotic of high dose for a long time, yet because the drug resistance that bacterium constantly produces makes the antibiotic curative effect very micro-.。
For the diarrhoea of weanling pig, most of plants control by vaccinate, but sucking pig weaning stage physique a little less than, the vaccine injection meeting bring stress, the problem of immuning failure often appears.In the selection of raw material, contain a large amount of ANFs without fermentation and dregs of beans or the soybean of expanding treatment, aggravated the burden of digestive system, further reduced the digestibility of feed.For also not forming the dietary antigen of immune tolerance, can bring out immune response again, cause intestinal mucosa damage and enteron aisle fluid accumulation, form diarrhoea.Cause weaning pigs in the market that pretty good palatability and nutritional labeling are arranged, but all ignored the not yet full grown fact of sucking pig digestive tract function and immunologic function, such as, micro-ecology and enzyme preparation composition are single, the acidulant proportioning is unreasonable, does not reach complementary synergy etc. between different acid, contains a certain amount of antibiotic, more easily cause intestinal bacilli illness, thus the generation of the disease that causes weaning.
Summary of the invention
The object of the invention is to provide a kind of green, safety, the weanling pig that contains plant extracts composition nonreactive feed formula, this feed is fully in conjunction with the physilogical characteristics of weanling pig, can solve the weanling pig immunologic inadequacy, resistance against diseases is not strong, the digestion secretase is not enough, the gut development imperfection, abilities of digestive and absorption is poor, the problems such as easy diarrhoea.
A kind of weanling pig nonreactive feed formula, it is comprised of popcorn, fermented bean dregs, soybean, soya-bean oil, fish meal, whey powder, piglet premix, plant extracts additive, coated acidulant, probiotics and complex enzyme formulation, and its various composition ranges are:

Below the effect of each main adding ingredient of technical scheme in this specific embodiment is done further to set forth clearly:
Owing to containing the approximately starch of 70% left and right in corn, therefore, improving the cornstarch utilization rate is to improve the key of livestock and poultry cultivation efficiency of gain and feed efficiency, and have the crystal structure of the antiacid antienzyme of significant proportion in amylum body and be unfavorable for digesting and assimilating of animal, must allow crystal structure disintegrate (being gelatinization) could fully be hydrolyzed by enzyme and improve digestibility.Described popcorn refers to the corn process expanded, and the starch molecule link originally contained is opened, and the resistant starch composition of former low-solubility is degraded to the solubility reduced sugar, protein slaking sex change, and digestibility rises, and lignocellulose degradation is for can digest fiber.
Described fermented bean dregs specifically refers to a kind of fermented type feed that utilizes microbe fermentation method to prepare, this fermented bean dregs macro-molecular protein of can degrading is on the one hand produced little peptide, generates the various active factors such as multiple-microorganism and enzyme, acid, vitamin, isoflavones simultaneously; On the other hand, can eliminate the ANFs in dregs of beans, improve the nutritive value of dregs of beans.Effectively promote digestion and the absorption of piglet to nutrition.When sufficient nutrition is provided, improved the immunity function of weanling pig.
Because steam fish meal amino acid content is abundant, be conducive to weanling pig to amino acid whose sufficient the absorption, therefore the fish meal in this specific embodiment preferably adopts the steam fish meal.
Described plant extracts additive has the piglet of raising immunity of organisms, suppresses the propagation of harmful bacteria, the effect of pre-anti-diarrhea; Wherein said aloe extract, mainly be comprised of mannose, galactolipin, glucose, wood sugar, arabinose, rhamnose, has the various biological effects such as antibacterial, lipopenicillinase, enhancing immunity, and have no side effect; Described Radix et Caulis Opuntiae Dillenii extract is containing multiple Flavonoid substances, as Quercetin-3-grape glucoside etc., especially cactus has clearing heat and detoxicating, antibacterial and antiinflammation: cactus also has good inhibitory action to staphylococcus aureus, proteus, Escherichia coli, bacillus subtilis, Bacillus cercus; The main component of described only dysentery grass extract is carvacrol and Thymol, belong to the bioflavonoid compound, its extract can promote animal to organic digestion, accelerate the renewal rate of intestinal villus surface-ripe enterocyte, the maturation of alimentary canal endodermis had to facilitation, because it has destruction to the pathogen cell membrane, thereby it is attached to reduce pathogen growing on the alimentary canal endothelium simultaneously, improve the absorption of nutritional labeling, strengthen humoral immunity and the cellular immune function of body; The described Radix Astragali, Radix Codonopsis, matrimony vine, folium cortex eucommiae and hawthorn can significantly increase Bacillus acidi lactici and the bifidobacteria in 40 age in days weanling pig enteron aisles, large intestine Ai Xishi bacterium index and Incidence of Diarrhea obviously reduce, and can improve daily gain 5.5~13.22%, the material anharmonic ratio reduces by 6.64~15.03%.
