Description

Animal feed additive using agricultural wastes and process for preparing the same}

The present invention relates to a feed additive for animal husbandry using agricultural by-products or wastes, and a method for manufacturing the same, more specifically, by using agricultural wastes or by-products that are inexpensive to purchase raw materials as materials, nutrient-rich livestock without burden of raw materials The present invention relates to a feed additive for livestock using agricultural waste or by-products and a method for manufacturing the same, which enables environmentally friendly recycling of resources by manufacturing the feed additive.

Agricultural wastes or by-products, including onion peels, are mostly collected as garbage and disposed of on the site, or used as fertilizer by landfill or even if the price or cost is not appropriate, it is economical even if it is not particularly damaged. For this reason, there have been cases of landfill. In other words, regardless of the product status of agricultural products, depending on the economic situation, agricultural products and their by-products are often discarded without special use, and economic processing must also be considered for processing agricultural by-products or wastes after processing. .

On the other hand, animal feed is divided into several types such as single feed, mixed feed, and auxiliary feed, and is used according to the purpose. Single feed refers to livestock feed that is not mixed with other feeds, combined feed means feed mixed with various feeds, and supplementary feed means feed added for the purpose of preventing quality degradation or increasing utility. do.

Among the substances used as auxiliary feeds, substances added to feeds to prevent deterioration of quality include preservatives, anticoagulants, binders, emulsifiers, antioxidants, and antifungal agents, and are added to feeds to increase utility. Are flavoring agents, non-proteinaceous nitrogen compounds, silicate agents, colorants, extractants, buffers, oligosaccharides, enzymes, probiotics, amino acids and vitamins.

More than 95% of domestic animal feed is dependent on imports. Continued increases in international grain, forage prices and oil prices are driving up production costs for livestock products. Therefore, as part of the increase in productivity by reducing feed costs in the livestock sector, efforts are being made to aggressively convert agricultural and food by-products produced in Korea into resources, and as a part of securing the base technology for continuous "circulating agricultural development" in the future. It will contribute to increasing the resource self-sufficiency rate and increasing livestock productivity.

Therefore, since the embodiments illustrated in the specification and the drawings shown in the specification are only the most preferred embodiments of the present invention, it is understood that there may be various equivalents and modifications that can replace them at the time of this application. shall.

The present invention has a carbon reduction effect by recycling and treating agricultural wastes or by-products as a main component, and converts useful components contained in agricultural wastes or by-products into biomolecules under appropriate conditions by adding microorganisms and enzymes to lower the molecular weight. The main technical features are to increase the absorbency of animals and to reduce the environmental burden by using waste resources as feed, which can provide various advantages in an environmentally friendly manner.

The method for producing livestock feed using agricultural waste according to the present invention is largely as shown in FIG. 1, pretreatment step of agricultural waste, compounding step, inoculation step of fermentation strain, concentration step, drying step, grinding step, sterilization and packaging This includes steps. It will be described below in detail with respect to the individual steps.

a) Pretreatment stage of agricultural by-products

First, the agricultural by-products to be disposed of are pre-treated for easy processing in a subsequent step.

The agricultural by-products may include by-products derived from a production process or a processing process including a growth stage of agricultural products or quasi-products that do not meet the standards, and examples thereof include, but are not limited to, onion by-products and pear by-products. , Soybean by-products, and green tea by-products.

The onion by-products may include, for example, onions that are disposed of, or processed by-products thereof, and the pear by-products may include products or pear-processed by-products having poor productability due to falling sugar or sugar content due to natural disasters. It may contain silver by-products or tofu-produced byproducts, and the green tea byproducts may preferably include green tea processing byproducts including green tea foil.

The agricultural by-products additionally include those selected from the group consisting of corn husk, soybean pods, sweet potato, potato sprouts, rice bran, barley bran, soybean meal, vegetable pak, drunk pear, fruit foil, rice stalk, straw, sukdae, barit and mushroom by-products. They may be used, and these may be preferably cut to a diameter of 20 mm or less and used.

The pre-treatment step is more preferably

a1) collecting agricultural by-products;

a2) removing foreign substances from the collected agricultural by-products;

a3) drying the collected agricultural by-products; And

a4) crushing the dried agricultural by-products to a particle size of 30 to 100 mesh; it is preferable to include.

The collection step can be obtained through a variety of channels, such as direct collection from the owner or farmhouse of a low-temperature storage warehouse to control the supply and demand of large-scale agricultural products through a recycling company.

Subsequently, it is good to remove foreign substances such as vinyl by a method such as washing, and then agricultural or by-products are naturally or hot-dried for 12 to 48 hours or in a dryer at 80 to 110° C. for 60 to 120 minutes. Dry to adjust the water content to 10-30%.

It is preferable to provide agricultural by-products in powder form, and it may be desirable to have a particle size of 30 to 100 mesh. If the particle size of the powder is less than or equal to 30 mesh, there is a risk of impeding workability and uniform fermentation. If it exceeds 100 mesh, the workability and fermentation efficiency are good, but the grinding process time is too long, resulting in a decrease in overall productivity and cost. There is a risk of losing competitiveness.

The crushing or cutting step may be performed by a mechanical crushing method, a cutter standard crushing method or a manual crushing method, but is not limited thereto.

b) compounding step

As a step of mixing the pre-treated agricultural by-products at a certain ratio, the mixing ratio of the agricultural by-products is 10 to 30 parts by weight of onion by-products, 30 to 50 parts by weight of pear by-products, 25 to 50 parts by weight of soybean by-products, And 5-25 parts by weight of green tea foil. In addition, solids and water containing agricultural by-products pre-treated for liquid fermentation are preferably adjusted to have a moisture content of 20 to 80% based on weight. As a result of various tests, the above-mentioned compounding range resulted in good results in the condition of the weight gain and meat quality of the animals by efficient fermentation and breeding tests.

c) inoculation stage

Subsequently, the strain for fermentation is inoculated to the blended agricultural by-products at a concentration of 0.1 to 3% by weight.

The fermentation strain preferred for inoculation in the step c) can be preferably used as long as it is a microorganism that has a beneficial effect on the physiological metabolism activity of the livestock by improving the efficacy of the feed mixture and improving the balance of the intestinal microflora of the livestock.

For such a fermentation strain (probiotics) may preferably be used to Bacillus (Bacillus) genus Lactobacillus bacteria (Lactobacillus), A saccharide in my process (Saccharamyces) genus Pseudomonas or the genus Cellulofine (Cellulomonas).

In particular, Bacillus subtilis , Bacillus natto , Bacillus amyloliquefaciens , Lactobacillus acidophilus , Lactobacillus plantarum , Lactobacillus plantar Lactobacillus brevis (Lactobacillus brevis), Lactobacillus casei (Lactobacillus casei), Lactobacillus buffer momentum (Lactobacillus fermentum), Lactobacillus ramno suspension (Lactobacillus rhamnosus), Lactobacillus ruteri (Lactobacillus reuteri), saccharose in my process three Levy jiae (Saccharomyces cerevisiae), saccharose in my process ellipsis Soy Ranges (Saccharomyces ellipsoideus), saccharose in my process formate Mohsen sheath (Saccharomyces formosensis), a saccharide My process car's Bergen sheath (Saccharomyces carlsbergensis), coarse My process mandrel Shurian a saccharide ( Saccharomyces mandshuricus and Saccharomyces coreanus , Cellulomonas cellulans , Streptococcus thermophilus , and Leuconostoc mesenteroides ( Phototrophic bacteria ), yeast (Yeast), EM bacteria (useful microbial bacteria) can be used as a probiotic, or commercially available probiotic.

In addition, those deposited in the microorganism depository can be obtained and used, examples of such being Bacillus subtilis (KCTC 3239), Lactobacillus acidophilus (KCTC 3111), Lactobacillus Plantarium ( Lactobacillus plantarum (KCTC 3104)), Lactobacillus Escidophilus NCFM ( Lactobacillus acidophilus NCFM, ATCC accession number SD5221), Lactobacillus salivarius Ls-33 ( Lactobacillus salivarius Ls-33, ATCC accession number SD5208) and lactose Bacillus plantarum Lp-115 ( Lactobacillus plantarum Lp-115, ATCC accession number SD5209), Saccharomyces cerevisiae (KCTC 7915) strains.

d) fermentation step

Subsequently, the inoculum is fermented at 25 to 43° C. for 3 to 30 days to convert the useful components contained in agricultural wastes or by-products into biomolecules under low molecular weight by adding useful microorganisms and enzymes to biochemically convert them under appropriate conditions. It can improve digestion and absorption.

Fermentation may be performed under agitation, if necessary, or on a rotary fermenter.

In addition, the fermentation step is Laccase, Cellulase, Pectinase, Xylanase, Polygalacturonase, termamyl, amylase And glucoamylase (glucoamylase) is carried out in the presence of a saccharide containing one or more enzymes and monosaccharides, disaccharides, or polysaccharides selected from the group may be efficient to decompose carbohydrates, cellulose, xylan, lignin, etc. into small molecules. The enzyme may be commercially available. In particular, it may be desirable to use pectinase, xylanase, and polygalacturonase in equal amounts.

The saccharides may include monosaccharides, disaccharides, and polysaccharides, and examples thereof include glucose, fructose, maltose, and starch. In addition, sugar, starch syrup or honey may be used.

The fermentation product after the fermentation process is completed is obtained by evaporating moisture using an evaporation device to obtain a concentrated fermentation product. In this step, a rotary vacuum evaporation apparatus may be used.

f) drying step

The concentrated fermentation product is dried naturally or hot air for 12 to 48 hours or dried at 80 to 110°C for 60 to 120 minutes in a conventional dryer to adjust the moisture content to 3 to 20%.

In the case of using a dryer, if the drying temperature is less than 80°C, there is a problem that sufficient drying is not performed or it takes a long time, and when it exceeds 110°C, there is a problem that the likelihood of carbonization of agricultural by-product powder increases, resulting in poor product quality. In addition, if the drying time is less than 60 minutes, there is a problem that the product quality is deteriorated due to a moisture problem when producing a product by applying the finished product due to insufficient drying, and when it exceeds 120 minutes, only energy is wasted without additional drying effect. There is.

g) powdering step

Subsequently, the dried fermentation product is powdered to a particle size of 30 to 100 mesh. For animal feed, even if the particles are somewhat rough, they do not affect the product very much, so the above particle size may be sufficient.

h) Sterilization step

The powder obtained in the above step is sterilized by a conventional method to improve the quality of the product, and is usually sterilized at 90 to 125°C for 5 to 60 minutes to kill microorganisms.

i) Packing steps

The feed additive obtained by powdering is packaged in a certain unit.

Feed additives using agricultural by-products manufactured in this way are rich in calories and nutrients, which can promote safe growth of livestock, and can be used in combination with blended feed, and can be used in combination with cattle, pig, sheep, goat, duck, It can be useful not only for raising livestock such as goose and chicken, but also for fish farming. In addition, it can be used as a feed for pets, cats, and other edible insects, such as pet dogs and cats.
