Abstract

The invention provides premixed feed for fattening pigs with a biological preservative. The premixed feed comprises 85%-97% of main material comprising corn, bean pulp and bran, 3%-15% of premixed material and 10mg/kg of natamycin biological preservative. The preferable mass percentages of the corn, the soyabean meal, rapeseed meal, cottonseed meal, the bran, the premixed material and natamycin are 50%-65%, 15-25%, 2%-10%, 2%-5%, 5-15% of bran, 3%-8% and 0.001% (10mg/kg) respectively. As the natamycin is used in the premixed feed as the biological preservative, the premixed feed is good in effect, small in use amount and high in safety compared with the available sodium diacetate chemical preservative. The premixed feed is used to conduct fattening feeding experiments on the pigs with weights of 30kg-100kg, and results indicate that the disease resistance of the fattening pigs fed by the premixed feed with the natamycin biological preservative is improved obviously.

Description

A kind of biological preservative growing and fattening pigs premixing feedstuff

Technical field

The present invention relates to a kind of growing and fattening pigs premixing feedstuff, be specifically related to the growing and fattening pigs premixing feedstuff prescription of applying biological anticorrisive agent, belong to livestock breeding industry.

Background technology

The anticorrisive agent of premixing feedstuff mainly is chemical preservative---sodium Diacetate at present, and its using dosage in premixing feedstuff is about 2kg/ ton feed, and using dosage is larger.Chemical preservative is controversial feed addictive always, because the chemical preservative using dosage is large, its security and potential harm do not allow people to ignore.

Natamycin (Natamycin) also claim natamycin, is a kind of important polyenes, and it is a kind of very strong antifungal agents.Since it can obligate inhibition saccharomycete and mould, stop the formation of aflatoxin in the filamentous fungi, and have antitrichomonal effect.Natamycin is nontoxic, and not mutagenesis, not carcinogenic, not teratogenesis, non-sensitization.Because it is insoluble in water and grease, be difficult to digested road and absorb, most of natamycin of taking in can be discharged with ight soil, so natamycin can not produce chemical sproof problem as conventional antibiotic.Natamycin is a kind of additive of safe, eco-friendly feed anticorrosion mildew-resistant, the preliminary natamycin that experimental results show that can also suppress the animal intestinal harmful fungoid, improve the animal disease resistant ability, it has obvious effect as feed addictive to security and the product quality that promotes feed.

At present natamycin has been used among medical treatment (the fungus-caused eye keratitis of external curing etc.), food, feed, the grain storage, and particularly the application of, finished product fresh-keeping at raw-food material aspect anticorrosion shown good prospect.At present, the countries such as the U.S., Holland, Belgium, France, Spain, Italy, Sweden all allow natamycin to be used for the anticorrosion of cheese and hard sausage, and Holland also ratifies natamycin and is used for the anticorrosion of apple and pear and other fruits.As far back as 1997, China Ministry of Public Health and relevant departments of food industry section approved natamycin were as food preservative.New " the food additives use sanitary standard " publicized and implemented in 2008 (GB2760-2007) in clear its using dosage: cheese 0.3g/L, cake 0.2g/kg, sauce spiced and stewed food 0.3g/kg, fruit juice 0.3g/kg, fermented wine 0.01g/L.Its using dosage is 1/5 ~ 1/10 of general chemical classes anticorrisive agent, and does not change the local flavor of food.Natamycin is as a kind of pure-natural biological anticorrisive agent, realizes substituting of biological preservative at feedstuff industry, is conducive to the enhancing of the market competitiveness of the lifting of product quality and enterprise, promotes the benign development of modern farming enterprise's aquaculture.

Summary of the invention

The growing and fattening pigs premixing feedstuff prescription that the purpose of this invention is to provide a kind of applying biological anticorrisive agent realizes that the growing and fattening pigs premixing feedstuff without chemical preservative, has improved the security of growing and fattening pigs premixing feedstuffs.

The technical scheme that the present invention takes: formula components comprises major ingredient, premix and the biological preservatives such as corn, dregs of beans, the dish dregs of rice, cotton dregs, wheat bran.Major ingredient accounts for 85%-97%, and premix accounts for 3%-15%, biological preservative (natamycin) consumption 10mg/kg.The prescription of its premix: compound amino acid 40～50%, B B-complex 25～35%, composite trace element 20～30%.It more than is mass percent.

This prescription premixing feedstuff is applicable to fattening of 30-100kg pig in growth period.

For achieving the above object, premixing feedstuff prescription preferred percent content ratio range of the present invention is as follows:

Corn: 50% ~ 65%; Dregs of beans: 15 ~ 25%;

The dish dregs of rice: 2% ~ 10%; Cotton dregs: 2% ~ 5%;

Wheat bran: 5 ~ 15%; Premix: 3% ~ 8%

Natamycin 0.001%, perhaps 10mg/kg.

For guarantee the homogeneity of natamycin in premixing feedstuff, first natamycin is mixed with suitable quantity of water that being prepared into emulsion by ultrasonic wave is sprayed in the wheat bran in the batch mixing process, the sprinkling process is fully mixed.Fully mix with premix afterwards, the last mixing with major ingredients such as corn flour, bean cake powders gets final product.The as far as possible lucifuge operation of premix process.

Compare by the premixing feedstuff of anticorrosive mildewproof experiment with the sodium Diacetate chemical preservative that uses, experimental result shows: the natamycin using dosage is little, and its anti-mold effect is suitable with the sodium Diacetate effect in 3 months experiment periods, and use cost is lower slightly.Natamycin is when working concentration is 10mg/Kg in premixing feedstuff as biological preservative, and the anti-effect of going mouldy of the sodium Diacetate of its antiseptic effect and 2000mg/Kg is suitable.

Adopt premixing feedstuff of the present invention that 30kg ~ 100kg body weight pig is fattened the experiment of feeding, the result shows that the resistance against diseases of the growing and fattening pigs that the premix of use natamycin biological preservative is fed obviously strengthens.
