Abstract

The invention discloses an antimicrobial-free feed for growing pigs. The antimicrobial-free feed comprises 45-65wt% of corn, 15-25wt% of soybean meal, 1-3wt% of chyle fat, 5-15wt% of wheat bran, 0.2-0.3wt% of a mineral matter premix, 0.02-0.03wt% of a vitamin premix, 0.1-0.2wt% of calcium hydrogen phosphate, 0.1-0.5wt% of stone flour, 0.1-0.2wt% of amino acid, 0.1-0.4wt% of salt, 0.03-0.05wt% of Radix Codonopsis, 0.03-0.08wt% of Radix Astragali, 0.03-0.08wt% of Rhizoma Atractylodis Macrocephalae, 0.03-0.08wt% of dry ginger, 0.03-0.1wt% of Poria cocos, 0.01-0.02wt% of tea tree oil and 0.02-0.04wt% of Fructus Rosae Laevigatae. A preparation method of the antimicrobial-free feed concretely comprises the following steps: receiving, cleaning, metering, crushing, burdening, mixing, granulating, carrying out classified screening, adding a liquid, packaging, and storing. The antimicrobial-free feed has the advantages of enhancement of the nonspecific immune functions of weaned piglets, substantial improvement of the immune effects of swine fever vaccines, improvement of the weight gain, and reduction of the feed conversion rate.

Description

Nonreactive feed of a kind of pig that grows and preparation method thereof

Technical field

The present invention relates to nonreactive feed of a kind of pig that grows and preparation method thereof, belong to feed product field.

Background technology

From the fifties in last century, aureomycin is by U.S. FDA approval for since feed addictive, and successively tens of kinds of antibiotic go through as the growth promoter of animal, and have promoted to a great extent the intensive degree of animal husbandry, and have brought huge economic benefit.Therefore,, in order to improve livestock and poultry cultivation economic benefit, aquaculture antibiotic is widely applied and occurs the situation of abuse in animal and fowl fodder is produced.Yet Long term Animal is used many adverse consequences of having brought of Antibiotic Additive, wherein topmost is exactly to cause the bacteria's numbers and species in animal body with drug resistance constantly to increase, the drug resistance of bacterium also can level transmission between animal and human, has increased the very big concern of people to the caused public health problem of bacterial drug resistance.Therefore, a plurality of countries and regions recent two decades such as European Union, Japan pay close attention to the antibiotic risk of animal always, and have progressively forbidden being used as in feed somatotrophic Multiple Classes of Antibiotics.Animal obviously declines by the resistance that antibiotic another large consequence is exactly animal, and the onset risk of various infectious diseases increases substantially.In addition, because Modern Animal Husbandry is the production performance that covets to a great extent, and ignored product quality.Although antibiotic application has improved the speed of growth of animal and the utilization ratio of feed, had a strong impact on but then local flavor and the quality of meat.

Summary of the invention

The object of this invention is to provide nonreactive feed of a kind of pig that grows and preparation method thereof, solve in feed and add medicament residue, drug resistance and the environmental pollution that antibiotic brings.In addition, compare with conventional feed after adding Chinese herbal medicine in feed, can improve the immunity of pig, reduce the onset risk of animal.

The present invention adopts following technological means to realize:

The grow nonreactive feed of pig, is comprised of following parts by weight formula:

Comprise basal feed component and core interpolation component, described basal feed component comprises:

Corn: 45-65%, dregs of beans: 15-25%, chyle fat: 1-3%,

Wheat bran: 5-15%, mineral matter pre-mixing agent 0.2-0.3%, vitamin premix: 0.02-0.03%,

Calcium monohydrogen phosphate 0.1-0.2%, stone flour: 0.1-0.5%, amino acid: 0.1-0.2%, salt: 0.1-0.4%;

Described core is added component and is comprised:

Radix Codonopsis: the 0.03-0.05% Radix Astragali: 0.03-0.08%

The bighead atractylodes rhizome: 0.03-0.08% rhizoma zingiberis: 0.03-0.08%

Poria cocos: 0.03-0.1% tea oil: 0.01-0.02%

The fruit of Cherokee rose: 0.02-0.04%

The grow preparation method of nonreactive feed of pig, concrete steps are as follows:

Comprise: reception, cleaning, metering, pulverizing, batching, mixing, granulation, classifying screen, liquid add, package storage;

1.1, receive: after receiving raw material, check material quality;

1.2, cleaning: major ingredient enters before silos storage, just clear, secondary material can enter batch bin after clearing up, and cleaning process comprises screening and magnetic plant, after magnetic plant is arranged at screening;

1.3, metering: Jin factory, warehouse entry and enter workshop etc. and locate to arrange measuring equipment, to major and minor material metering;

1.4, pulverize: when the granularity of raw material meets instructions for use, do not pulverize, comprise the coarse crushing of cake class and Ordinary pulverization, pulverizer sieve diameter: wheat: 2.0mm, corn: 2.5mm;

1.5, batching: be used in combination the burden balance of different range of weighing, the material that is less than burden balance maximum capacity 5% is not participated in the batching of these burden balance directly, adopts and manually weighs or the metering of micro-ingredients scale for microcomponent, then after premixed, participates in batching; During batching, weighing must be accurately, and error is no more than 0.5%(500 ± 2.5Kg);

1.6, mix: after having prepared burden, preferential according to major ingredient, the order of the follow-up interpolation of auxiliary material enters mixer successively, start to calculate incorporation time after entering mixer completely, mix 240 seconds;

1.7, granulate: after having mixed, before material pelletization, need through magnetic separation, after magnetic separation completes, granulate, pelleting temperature: 68 ℃, pressure: 4KG; Ring die pelleter: 2.8mm; Granulation divides through cooling, the particle of normal temperature, particle by particle

Level is processed,

1.8, classifying screen: end sieve: 14 orders,

Face sieve: 8 orders;

1.9, liquid adds: oil spout;

1.10, packing: the large bag of 40Kg/; 20Kg/ parcel.

The present invention compared with prior art, has following obvious advantage and beneficial effect:

The feed of the antibiotic preparation in the alternative feed of compound component that the present invention utilizes plants essential oil to combine with Chinese herbal medicine, when carrying out animal feeding, finds that the production performance (speed of growth, feedstuff-meat ratio) of test pig is close with the antibiotic feed of interpolation.But there were significant differences for the whole immune state of the pig of the beverage of the present invention of feeding, the non-specific immune function of test pig strengthens, and the immune effect of hog cholera vaccine is also significantly increased compared with control feed group, improves weightening finish and reduces the advantage of feedstuff-meat ratio.
