Description

Description
FERMENTED FEEDS FOR LIVESTOCK FARMING USING LACTIC ACID BACTERIA AND YEAST AND PROCESSING
METHOD THEREOF
Technical Field
[1] The present invention relates to fermented feeds for livestock farming with lactic acid bacteria and yeast and preparation methods thereof and, more particularly, to fermented feeds for livestock farming prepared by using lactic acid bacteria and yeast which can survive even at high temperature and under low pH and a method for preparing the same. Background Art
[2] In the last few decades, domestic livestock industry generally used antibiotics to protect and treat livestock, promote growth of livestock and improve efficiency of feeds for livestock, thereby enhancing productivity of livestock. However, if antibiotics are continuously taken, these may increase micro-organisms having tolerance to the antibiotics and cause deterioration of efficacy thereof, or may remain in livestock products to have negative effects on a human body. Accordingly, use of antibiotics for accelerating growth of livestock is being gradually restricted. In fact, harmful impurities remaining in livestock products often cause troubles and come to the front as a direct obstacle to pork export to Japan. Accordingly, there is a strong requirement for an alternative material to replace conventionally available antibiotic products with negative features described above.
[3] As solutions of the above problems, there have been generally proposed fermented feeds using micro-organisms, most of which comprise single strain cultures representatively including fungi such as yeast or mold. But, in view of various advantages including, for example, economic benefits of livestock farms accomplished by improving efficiency of feeds to reduce amount thereof or lowering death rate of livestock, nutritional control for growth of livestock, protection from diseases, decrease of stress and the like, it is assumed that combined micro-organisms comprising different species of beneficial and functional micro-organisms are more effective than single strain cultures.
[4] Polymeric materials generated during fermentation of soybean are generally classified into gamma(γ)-polyglutamate and polyfructan. γ-polyglutamate which is well known to have moisturizing function, anti-inflammatory activity and cell activation can be preferably employed as raw material for cosmetics and, if γ- polyglutamate is used together with anti-tumor chemicals such as Taxol in medical ap- plications, such polymeric material can greatly improve efficacy of the chemicals. On the other hand, polyfructan coexists with γ-polyglutamate and serves to amplify performances of γ-polyglutamate such as moisturizing function and anti-inflammatory activity.
[5] For instance, it was reported that, when microbial polyfructan called Levan is taken in the form of dietary fiber, polyfructan can make a person to feel satiated, in turn, suppress and control appetite, and can inhibit proliferation of harmful intestinal bacteria while assisting growth of lactic acid bacteria in intestines.
[6] As an illustrative example of soybean hull fermentation methods for industrial applications, Korean Patent Registration No. 0003751 disclosed a method for preparation of fermented feeds using agricultural wastes. Disclosure of Invention Technical Problem
[7] The present invention is directed to fermented feeds for livestock farming prepared using lactic acid bacteria and yeast, which are applicable in environmentally friendly bio-farming industries, as well as a method for preparation of the fermented feeds. Technical Solution
[8] In order to accomplish the above object, the present invention provides fermented feeds for livestock farming, which include at least one selected from a group consisting of Lactobacillus fermentum JS (KCCM 10499), Pichia kluyveri and Saccharomyces cerevisiae.
[9] The present invention also provides a method for preparation of a fermented feed composition, which comprises inoculating at least one selected from Lactobacillus fermentum JS (KCCM 10499), Pichia kluyveri and Saccharomyces cerevisiae in a medium containing spent substrate from mushroom cultivation, rice bran, soybean hulls and sesame dregs, then fermenting the cultured product.
[10] Hereinafter, the present invention will be described in detail below with reference to the accompanying drawings.
[11] With regard to the present invention, using Lactobacillus fermentum JS (KCCM
10499), Pichia kluyveri and/or Saccharomyces cerevisiae strains exhibits beneficial effect in pig farming or chicken farming and provides a fermented feed composition for environmentally friendly bio-farming.
[12] The fermented feed composition according to the present invention is preferably prepared by inoculating at least one selected from a group consisting of Lactobacillus fermentum JS (KCCM 10499), Pichia kluyveri and Saccharomyces cerevisiae in a medium containing spent substrate from mushroom cultivation, rice bran, soybean hulls and sesame dregs, then fermenting the cultured product. [13] Such fermentation is preferably conducted at 35 to 5O0C for 24 to 72 hours.
[14] The prepared medium preferably contains 60 to 80% by weight (hereinafter, often abbrev. to [wt.%] of spent substrate from mushroom cultivation, 5 to 20wt.% of rice bran, 3 to 10wt.% of soybean hulls and 2 to 10wt.% of sesame dregs.
[15] Also, the medium may further include 5 to 35wt.% of molasses or 3 to 12wt.% of glucose.
[16] In the present invention, the term [spent substrate from mushroom cultivation] means mushroom medium waste remaining after completing cultivation of mushroom and harvesting mushrooms. Generally, sawdust of oak or pine trees is used as the mushroom medium to cultivate mushrooms by a typical process comprising the steps of: filling the sawdust in a plastic container with excellent thermal resistance; sterilizing the container under high pressure after putting a lid on the container to seal the container; carrying out sterile inoculation of mushroom spawn to cultivate mushrooms; harvesting the cultivated mushrooms; and blowing external air into the container to discharge the mushroom medium outside, which is usually called the spent substrate from mushroom cultivation in the related art.
[17] Illustrative examples of such spent substrate from mushroom cultivation preferably include media from pine mushroom, shiitake mushroom, agaric mushroom, lespedeza mushroom, Sarcodon aspratus, etc. but are not particularly restricted thereto so far as they are mushroom media capable of being cultivated.
[18] With regard to the present invention, after culturing Lactobacillus fermentum JS,
Pichia kluyveri and Saccharomyces cerevisiae strains in corresponding media, respectively, the cultured products are subjected to cell separation by using a centrifugal separator. Dextrin or skim milk powder is added to the separated cells, followed by freezing the mixture at -8O0C and drying the frozen material with a freeze dryer to preferably obtain a powdery product.
[19] The fermented feed composition described above preferably comprises Pichia kluyveri or Saccharomyces cerevisiae yeast in addition to Lactobacillus fermentum JS lactic acid strains.
[20] Such fermented feed composition preferably contains each of the different strains in the range of IxIO5 to lxlO11 CFU/g.
[21] The fermented feed composition of the present invention may be blended with other typical materials to produce a livestock feed composition.
[22] Particularly, 35 to 65wt.% of the above fermented feed composition is blended with
5 to 25 wt.% of milled corn powder, 10 to 30wt.% of wheat bran, 5 to 30wt.% of corn husks, 4 to 15wt.% of molasses, 5 to 10wt.% of glucose, 0.2 to 1.5wt.% of phosphoric acid, 0.3 to 2.5wt.% of calcium, 0.1 to 0.5wt.% of vitamin complex, 0.5 to 3wt.% of limestone and 0.1 to lwt.% of salt to form a mixture and the mixture is placed and fermented in a fermenter at 35 to 500C for 30 minutes to 10 hours to produce a livestock feed composition 1, which is preferably adapted for livestock feeds provided during a growing period of livestock.
[23] 40 to 70wt.% of the livestock feed composition 1 produced above is combined with
10 to 35wt.% of compressed corn, 8 to 20wt.% of lupine beans, 2 to 6wt.% of corn husks, 1.5 to 5wt.% of wheat bran, 3 to 12wt.% of molasses, 3 to 8wt.% of glucose, 0.1 to 0.5wt.% of vitamin complex, 0.2 to 1.5wt.% of phosphoric acid, 0.3 to 2.5wt.% of calcium and 0.1 to 0.5wt.% of limestone to form a mixture and the mixture is placed and fermented in a fermenter at 35 to 500C for 30 minutes to 10 hours to produce a livestock feed composition 2, which is preferably adapted for livestock feeds provided during a former period of fattening of livestock.
[24] Alternatively, 15 to 40wt.% of the livestock feed composition 1 produced above is combined with 25 to 50wt.% of compressed corn, 20 to 40wt.% of lupine beans, 1 to 5wt.% of corn husks, 1.5 to 5wt.% of wheat bran, 4 to 13wt.% of molasses and 5 to 9wt.% of glucose to form a mixture and the mixture is placed and fermented in a fermenter at 35 to 500C for 30 minutes to 10 hours to produce a livestock feed composition 3, which is preferably adapted for livestock feeds provided during a latter period of fattening of livestock.
[25] Limestone in the present invention is used to supplement calcium to a mixed feed invention, which is better as CaCO content is higher, and preferably has a particle size ranging from 100 to 200 mesh.
[26] The fermented feed composition according to the present invention is preferably fed to livestock in order to obtain fresh and processed meat with superior meat quality.
[27] Livestock mentioned in the present invention is at least one selected from cattle, pig, chicken and duck.
Advantageous Effects
[28] As described in the following detailed description of preferred embodiments and examples, in case that the fermented feeds according to the present invention are provided to cattle on feed, it was possible to increase weight of cattle, produce high quality meat and save feed cost of 30% or more. Moreover, the inventive feeds have advantages that they reduce disease incidence rate to 0%, degrade ammonia mostly causing odor generation as one of features of lactic acid to considerably reduce offensive odor in livestock barns, and can attain environmentally friendly bio-farming substantially free of vermin such as flies or mosquitoes.
[29] Compared to conventional lactic acid bacteria which are very susceptible in heat and acid, Lactobacillus fermentum JS used as strains for fermentation in the present invention have high thermal resistance and acid resistance and can degrade ammonia (NH ). More particularly, for bio-farming, internal temperature during fermentation (that is, temperature of fermenting materials) rises to about 850C at which normal lactic acid bacteria are sterilized while the total number of Lactobacillus fermentum JS strains is increased. That is, the strains are proliferated and can secrete various functional materials from a medium raw material and degrade ingredients contained in the feeds such as lignocellulose into a digestible form, thereby promoting digestion of the feeds by livestock. Pichia kluy veri yeast strains naturally generated during fermentation of red or white wine are well known as major causative organisms. Sac- charomyces cerevisiae yeast strains are mostly used for fermentation of bread. Both of the yeast strains are rich in nutritional ingredients such as protein, vitamins, minerals, etc. to function as nutrients for livestock. Also, the yeast strains can coexist with and be simultaneously cultured together with Lactobacillus fermentum JS strains in the same medium to endow a variety of beneficial features to the fermented feeds.
[30] Briefly, the strains described above are expected to exhibit desirable effects in that they provide abundant nutritional ingredients, function as probiotics to promote digestion and absorption of the ingredients, activate intestinal flora, and generate functional materials for immunity enhancement. Brief Description of the Drawings
[31] The above objects, features and advantages of the present invention will become more apparent to those skilled in the related art in conjunction with the accompanying drawing. In the drawing:
[32] Fig. 1 illustrates processes of preparing four kinds of livestock feeds such as fermented feed, feed at a growing period, feed at a former period of fattening of livestock and feed at a latter period of fattening of livestock, respectively. Best Mode for Carrying Out the Invention
[33] Hereinafter, the present invention will be described in detail from the following preferred examples with reference to the above drawing. However, these are intended to illustrate the invention as preferred embodiments of the present invention and do not limit the scope of the present invention.
[34] EXAMPLE 1 : processes of preparing fermented feed, feed at a growing period. feed at a former period of fattening of livestock and feed at a latter period of fattening of livestock
[35] Fermented feed, feed at a growing period, feed at a former period of fattening of livestock and feed at a latter period of fattening of livestock were prepared by corresponding processes simply shown in Fig. 1, respectively.
[36] In the process of preparing the fermented feed, Lactobacillus fermentum JS strains and Saccharomyces cerevisiae yeast strains were used. [37] Lactobacillus fermentum JS strains were obtained by inoculating Lactobacillus fermentum JS in MRS medium and culturing at 4O0C for 1 to 7 days. 50 liters of water was placed in a 50L culture bath, sterilized at 1210C for 10 to 15 minutes and cooled to 30 to 450C. Next, a medium composition was prepared by adding 5 to 15g of protease peptone No. 3, 3 to 1Og of beef extract, 10 to 30g of glucose, 3 to 15g of sodium acetate and 1 to 8g of ammonium citrate per 1 liter of water to the above culture bath and diluting the mixture. 40ml of sterile cold water was added to a 50ml flask under sterile conditions, followed by inoculation of Lactobacillus fermentum JS strains in the flask, which was cultured in MRS medium. After dilution of the inoculated strains, the flask was placed in the culture bath and cultured at 30 to 450C for 1 to 3 days. When the total number of lactic acid bacteria in the cultured solution was 10 CFU/g or more, the solution was subjected to cell separation using a centrifugal separator to obtain 3ml of cells in 1 liter of a crude solution. Dextrin or skim milk powder was added to the cell solution and the mixture was lyophilized at -8O0C by a freeze dryer to produce a powdery product.
[38] Culture of Saccharomyces cerevisiae yeast strains was performed by a process comprising: adding 2 to 5g of yeast extract, 2 to 5g of malt extract, 3 to 7g of peptone and 5 to 15g of glucose to 1 liter of water; sterilizing the mixture; inoculating 1 to 3% of yeast, which was pre-cultured in YM liquid medium, in the above mixture; and culturing the inoculated yeast at 250C for 5 days. The cultured yeast strains were subjected to cell separation using a centrifugal separator to obtain 3ml of cells in 1 liter of a crude solution, followed by adding dextrin or skim milk powder to the cell solution and lyophilizing the mixture at -8O0C with a freeze dryer to produce a powdery product.
[39] The prepared Lactobacillus fermentum JS and Saccharomyces cerevisiae yeast strains were combined together and the total number of the strains was controlled to 10
CFU/g or more. The strains were used to produce a fermented feed comprising glucose, rice bran, lactose and skim milk powder.
[40] The following Tables 1 to 3 show composition of ingredients in each of livestock feeds such as fermented feed, feed at a growing period, feed at a former period of fattening of livestock and feed at a latter period of fattening of livestock.

[44] EXAMPLE 2: Analyses of ingredients in fermented feed and feed at a growing period [45] Ingredients in the fermented feed and the feed at a growing period prepared in Example 1 were analyzed. From the results shown in the following Tables 4 and 5, it was demonstrated that the feed at a growing period has lower content of carbohydrates and higher contents of crude protein and crude fat, compared to the fermented feed.

[48] EXAMPLE 3: Results of experiments for effect of additional feed according to the present invention in pork farming
[49] 40 weanling piglets were raised for 17 weeks with a feed preparation containing
10% of the additional feed according to the present invention, that is, the feed at a growing period (hereinafter, abbrev. to additional feed group), and another 40 weanling piglets raised with a conventionally available mixed feed were designated as a control group. After raising 120 weanling piglets for 17 weeks, the grown piglets underwent measurement of weight increase and feed conversion rate. As a result, the control group had an average increase in weight of 564.6g per day while the piglets in the additional feed group exhibited 611.9g per day with a difference of 47.3g from the control group. Accordingly, it was found that the present inventive feed effectively increased weight of piglets. For the feed conversion rate, the control group consumed 1.65kg of feed per day while the additional feed group consumed 1.61kg of feed per day, which was 4Og less than the feed amount required in the control group. Accordingly, it was demonstrated that the present inventive feed exhibited higher feed conversion rate than that of the control group.
[50] From experiments using a feed preparation produced by preparing a fermented feed with lactic acid bacteria and yeast and adding the prepared feed to a mixed feed commercially available in markets, it was found that the piglets were grown to standard market pigs with a weight of about 100 to 110kg, 5 months after birth.
[51] EXAMPLE 4: Results of experiments for inhibition of diseases in pork farming
[52] During raising 120 weanling piglets for 17 weeks, it was observed whether the piglets suffered from diseases. As a result of measuring diarrhea index for each of the piglets, since 15 piglets in the control group had acute diarrhea while the only two piglets in the additional feed group showed mild diarrhea symptoms, it was demonstrated that the additional feed group was noticeably better than the control group in view of diseases. For pig death rates, it was observed that two among 40 piglets in the control group died due to diseases such as diarrhea while none of the piglets in the additional feed group containing lactic acid yeast according to the present invention died.
[53] EXAMPLE 5: Chicken farming -420 chickens, two experiments for 32 days
[54] After raising 420 chickens for 32 days, weight increase and feed conversion rate were measured for the chickens. As a control group, a commercially available mixed feed was used. An additional feed group was to use a feed preparation produced by adding 10% of the fermented additional feed according to the present invention to a commercially available mixed feed. The chickens raised in the additional feed group showed an increase in weight with an average of 9Og higher than that of the control group, as well as a feed conversion rate of 1.77kg with an average of 12Og lower than that of the control group which was 1.89kg. Accordingly, it was demonstrated that the additional feed group has excellent feed conversion rate.
[55] EXAMPLE 6: Results of determining carcass grade of cattle on feed
[56] By using each of the fermented feeds prepared using Lactobacillus fermentum JS strains and Saccharomyces cerevisiae yeast strains according to the present invention and general mixed feeds, cattle on feed aged 4 months after birth were grown to 28 months after birth. The fermented feeds used for raising the cattle on feed were four kinds of feeds prepared as described in Example 1. More particularly, the feed at a growing period was used for 4 to 13 month old cattle, the feed at a former period of fattening of livestock was used for 14 to 22 month old cattle, and the feed at a latter period of fattening of livestock was provided to 23 to 28 month old cattle. As a result, 91.4% of the cattle on feed raised with the fermented feeds according to the present invention got first grade or higher in the carcass grade determination and the highest unit price (see Table 6).

[58] EXAMPLE 7: Cost reduction effect of fermented feeds according to the present invention
[59] In order to determine effect of decreasing feed cost for the present inventive fermented feeds, the feed cost was compared to that in case of using any general mixed feeds.
[60] Reduction of feed cost was estimated for each cattle on feed during raising the cattle for 23 months and, from the estimated result, it was demonstrated that the fermented feeds exhibited a feed cost reduction rate of 31.7% compared to a mixed feed commercially available from P company, and 23.8% compared to another mixed feed commercially available from C company, as shown in Tables 7 to 9.
