CN101627746A - Fermenting bed raising method of high-quality lean-meat type high-bred pig - Google Patents

Abstract

The invention relates to a raising method of a high-quality lean-meat type high-bred pig, in particular to a fermenting bed raising method of a high-quality lean-meat type high-bred pig. Agricultural and sideline products such as saw dust, straws, peanut shells, and the like are used as fillers for providing a carbon source and changing the porosity of a fermenting bed; plain fills, green grass and cow manures are added on the basis of pig manures so as to increase the concentration of trace elements; thus, a proper environment is provided for the growth of pig and the increase of intramuscular fat to form more marbling high-quality pork.

Description

The high-quality lean-meat type high-bred pig fermenting bed raising method

Technical field

The present invention relates to a kind of water meat type breeding pig cultural method, particularly a kind of water meat type breeding pig fermenting bed raising method.

Background technology

High quality pork production aspect, after rabid ox disease (beef cattle), bird flu, clenbuterol, melamine (milk cow, bean powder) and malicious dumpling incident, compatriots' food security consciousness improves, the animal welfare theory begins to propagate in modernization, more values intramuscular fat, marbled high quality pork after laying particular stress on lean meat percentage.Chinese native pig breed is world-famous for so that meat is good, still, slows down growth rate than low metabolic rate, inquires into heredity with other factor, improves commodity hybridized pig choice meat production model problem and seems important.

Summary of the invention

The purpose of this invention is to provide a kind of premium muscle type breeding pig fermenting bed raising method, a kind of adapt circumstance is provided for the growth of pig,, form more marble grain high quality pork to improve intramuscular fat.

Technical scheme of the present invention is

A fermentation bed process flow process

Utilize agricultural byproducts such as wood chip, stalk, peanut shell to make inserts; the porosity of carbon source and change fermentation bed is provided; on the basis of pig manure, add plain soil, green grass, cow dung to increase the concentration of microorganism; judge the aerobic fermentation type with fermentation bed tempertaure changing pattern; judge environmental protection, reduce the air-polluting effect with air ambient index in giving up, establish the control of fermentation bed tempertaure material selection and condition.

The technological process of b choice meat

Under the conventional daily ration condition, analysis fermentation bed is estimated its environment richness and animal welfare and is improved degree the influence of animal behavior, and meat is improved; In the cement flooring district, in 2% grass meal daily ration, substitute corn, the alternative part dregs of beans of wheat bran, the alternative corn of barley with wheat.

The invention has the beneficial effects as follows and realize to raise district's original position fermentation, need not redundant space, do not have sewage discharge, odorless, reduce air pollution, the fecaluria fermentation process, the fat granule meat taste that evenly distributes obviously improves.

The pig house environment condition: CO2 concentration＜0.25%NH3＜10mg/m3PM10＜0.30mg/m3 does not have sewage discharge

Meat quality: the fat content 2.0%-4.0% of longissimus dorsi muscle, wherein 90% greater than 3.0%.PH16.0-6.8, yellowish pink scoring 3-4 branch

Embodiment
