CN104068227A - Antibiotic-free feed for the first phase of pig fattening and preparation method thereof - Google Patents

Abstract

The present invention discloses an antibiotic-free feed for the first phase of pig fattening, and the feed comprises the following ingredients, by weight, 46-65% of corn, 13-20% of soybean meal, 0-10% of fish meal, 5-15% of bran, 0.2-0.3% of a mineral premix, 0.02-0.03% of a vitamin premix, 0.1-0.2% of calcium hydrogen phosphate, 0.1-0.5% of stone powder, 0.1-0.4% of salt, 0.03-0.05% of codonopsis pilosula, 0.03-0.08% of astragalus membranaceus, 0.03-0.08% of atractylodes macrocephala, 0.03-0.08% of dried ginger, 0.03-0.1% of poria cocos, 0.01-0.02% of tea tree oil and 0.02-0.04% of rosa laevigata. The preparation method for the antibiotic-free feed includes the following steps: receiving, cleaning, measuring, crushing, material preparing, mixing, pelletizing, grading screening, liquid adding, packaging and storing. With the feed, the problems of drug residue, drug resistance and environmental pollution which are caused by addition of antibiotics to the feed can be solved. In addition, compared to the conventional feed, the feed into which the Chinese herbals are added has the beneficial effects of enhancing the pig immunity, reducing the incidence risk, and improving the pork product flavor.

Description

Nonreactive feed of a kind of growing and fattening pigs first stage and preparation method thereof

Technical field

The present invention relates to nonreactive feed of a kind of growing and fattening pigs first stage 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.But Long term Animal uses 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, multiple 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, have 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 growing and fattening pigs first stage and preparation method thereof, solve in feed and add medicament residue, drug resistance and the environmental pollution that antibiotic brings.In addition, in feed, add after Chinese herbal medicine compared with conventional feed, can improve the immunity of pig, reduce the onset risk of animal, improve meat quality and meat flavor.

The present invention adopts following technological means to realize:

The nonreactive feed of growing and fattening pigs first stage, is made up of following parts by weight formula:

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

Corn: 46-65%, dregs of beans: 13-20%, fish meal: 0-10%,

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%, 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%.

A preparation method for the nonreactive feed of growing and fattening pigs first stage, 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 cleaning, and cleaning process comprises screening and magnetic plant, after magnetic plant is arranged at screening;

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

1.4, pulverize: when the granularity of raw material does not meet instructions for use, 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; When 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 DEG C, pressure: 4KG; Ring die pelleter: 2.8mm; After granulation, divide through cooling, the particle of normal temperature, particle through particle

Level is processed,

1.8, classifying screen: end sieve: 14 orders,

Face sieve: 8 orders;

1.9, liquid adds: oil spout;

1.10, packaging: 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, in the time 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 overall 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.

Solve in feed and add medicament residue, drug resistance and the environmental pollution that antibiotic brings.In addition, in feed, add after Chinese herbal medicine compared with conventional feed, can improve the immunity of pig, reduce the onset risk of animal, can improve the local flavor of pork product simultaneously.
