What is the principle of use of feed starter culture

Feed starter contains a large number of microorganisms, such as lactic acid bacteria, yeast, bacillus, filamentous bacteria and other more than 80 kinds of microorganisms in ten genera. Nongshengle feed starter can decompose feed macromolecular organic matter (lignin, chitin, etc.) into small molecule substances such as monosaccharides and amino acids that are easy to digest and absorb, and produce and accumulate a large number of nutrient-rich microbial bacteria and useful metabolites, such as organic acids, vitamins, trace elements, etc., coupled with the existence of the bacteria itself and its secreted and synthesized active enzymes and other substances, which greatly improves the nutritional value of feed, the total amount of 18 kinds of amino acids increases significantly, and the increase of different nutrients is between 10-28%. Nongshengle feed starter has an obvious acidifying effect on feed, which can increase the content of amino acids in feed, improve the utilization rate of protein and amino acids, and promote animal growth.

In aquaculture, a class of substances that can increase the acidity of feed is called feed acidifiers. Acidifying the feed can improve the performance of the animals. In the process of fermenting feed, on the one hand, it can significantly reduce the pH value of the feed, play a role in feed acidification, reduce the pH value in the stomach, thereby activating the conversion of pepsinogen into pepsin and promoting the decomposition of protein; The effect is even more pronounced in young animals whose digestive systems are not yet fully developed.

On the other hand, acids can also reduce gastrointestinal motility and slow down emptying time, thereby improving digestion and absorption. At the same time, due to the combined effect of acidic substances, it can promote the absorption of calcium, phosphorus and other substances in the gastrointestinal tract.

The fermented feed is better for moving sheds, which can promote digestion, better absorb slag nutrients, and reduce some toxins. There will be a significant difference in the feed, whether it is the appearance and shape, or the smell, there is a very obvious difference.

The ingredients will change greatly, which can improve the nutrients of the camp, which can make the livestock infiltrate and stimulate the wild animals to absorb better, can make the nutrition more comprehensive, can remove pests and diseases, and can also enhance immunity.

The application of fermented feed in optimizing and improving water quality is the key to aquaculture and the guarantee of economic benefits. However, due to the limitations of traditional aquaculture models, water quality is susceptible to external factors. With the gradual application of fermented feed, its advantages in improving water quality are becoming more and more obvious.

Under the action of fermented feed, the metabolic function of aquatic animals can be improved, a stable feeding and digestion chain can be established, the discharge of harmful substances in the water can be greatly reduced, and the risk of water quality changes can be effectively avoided.

In addition, the fermented feed itself can rely on the biological barrier of beneficial microorganisms to form a dense membrane flora, and strive to reduce the entry of toxic and harmful substances into the animal's body. Under the action of beneficial bacteria, it can form beneficial effects such as oxidation, nitrification, ammoniation, nitrogen fixation, etc., greatly reduce the accumulation of organic matter in water, accelerate the degradation of harmful substances, make it an inorganic salt suitable for growth, thus forming a complete ecological circulation system, realizing the long-term balance of water quality, and finally achieving the purpose of purifying water quality.

The application of fermented feed in improving production performance: According to the principle of production transformation of fermented feed, a large number of live bacteria will be produced during the fermentation process. By entering the water body and the intestinal tract of the animal, its metabolic function will be improved, and nutrients such as amino acids, vitamins, and digestive enzymes will be effectively absorbed, thereby accelerating the growth of the animal.

Generally speaking, beneficial bacteria are high-protein substances that can form a variety of amino acids, B vitamins and other nutrients that meet the needs of animals. In the process of beneficial bacteria reproduction, they also produce proteases, lipases and other digestive enzymes, which can be used to regulate the balance of the body and further improve the nutrient absorption capacity of animals.

In addition, fermented feed can inhibit the production of seeds, provide a better environment for aquaculture, effectively improve the palatability of feed, increase animal feed intake, and maintain good feeding rules, thereby improving the utilization rate of aquatic feed and promoting economic benefits.

In conclusion, with the development of modern aquaculture technology, fermented feed has become a major trend in future development. Especially at the moment of advocating green environmental protection, fermented feed can better meet the market demand and increase the economic benefits of the aquaculture industry. In addition, the application of fermented feed can also enhance immunity, improve water quality, and improve production performance.

Fermented feed is bound to become the best choice for the aquaculture industry.

In this way, the nutritional value of the feed can be improved, the feed can be fermented, beneficial probiotics can appear, the balance of the microecology can be adjusted, the water quality can be optimized and improved, and some diseases can be prevented.

The nutrients of this feed are relatively high, which is very suitable for absorption, and there are a lot of microorganisms in it, which can regulate the ecological balance, kill some germs, and make some animals grow better and make the stomach and intestines better.

Fermented feed can convert some of the nutrients in the feed into nutrients that are better absorbed, and the fermented feed is also conducive to the absorption of animals, and the fermented feed can maximize the nutrition in the feed. Fermented feed is more conducive to the growth of animals, and fermented feed is more scientific.

In this way, microbial fermentation can be used to increase the yield of grain, and then the soil dominance can be improved, and the soil binding can be regulated, and the harmful bacteria in the soil can also be killed.

This kind of plastic is very easy to absorb, can be a good guarantee of benefits, is conducive to the metabolism of some animals, can prevent some intestinal diseases, regulate the health of the body.

Through fermentation, the feed can be effectively decomposed and converted into small molecules such as glucose and amino acids that are easily digested and absorbed by animals, so as to improve the nutritional value and utilization conversion rate of feed.

There are still many benefits of fermented feed, but when making fermented feed, it is best to add a professional feed starter to give full play to the advantages of fermented feed, which is manifested in the following points:

1. Reduce the cost of feeding. The energy feed fermented by Gymboree feed starter is converted into bacterial protein feed, and the full price feed is prepared with the fermentation material, which can reduce the amount of protein feed by about 50%, and soybean meal and fish meal can be used, thereby greatly reducing the total cost of feeding. Saving money means making money.

2. Improve the palatability of feed. The product after fermentation by feed starter is golden yellow, smooth to the touch, fragrant smell, excellent taste, very suitable for raw feeding, animals like to eat and eat more, greatly saving fuel and labor costs.

3. Detoxify and detoxify the feed Relying on the life activities and metabolites of the "functional" microorganisms contained in the Gymboree feed starter culture, the toxic and harmful substances contained in the feed (especially rapeseed cake and cottonseed cake) are degraded and removed, thereby greatly improving the safety of the feed and making cottonseed cake or rapeseed cake can be used instead of soybean meal.

4. Improve animal disease resistance. The microorganisms contained in the feed starter directly participate in the barrier function of the animal intestine, supplement the population and quantity of beneficial microorganisms in the animal intestine, form a "dominant beneficial bacterial community", prevent the colonization and growth and reproduction of pathogenic microorganisms, restore and maintain the microecological balance in the animal intestine, so as to improve animal immunity and disease resistance, make animals less sick, and save money for farmers.

5. Improve feed utilization. The powerful microbial flora contained in Gymboree feed starter can destroy the tough plant cell wall in feed raw materials, convert "macromolecules" such as cellulose and pectin into "small molecules" such as monosaccharides and oligosaccharides, and generate a variety of organic acids, microbiotics, biological enzymes, amino acids and other unknown growth factors, which greatly improves the nutritional level and digestion utilization rate of fermented materials, and completely changes the phenomenon of animals "eating but not melting" and "eating not growing meat".

1. First, mix the starter culture and the materials to be fermented fully (in order to achieve the purpose of mixing, the method of gradual dilution can be adopted).

2. Add water and mix well, and the moisture content of the material is generally controlled between 65% and 75%. The judgment method is: grasp the mixed fermentation materials tightly, see the watermark but not dripping on the finger seam, and loosen it to the ground to spread it is appropriate.

If the juice can be squeezed out and does not spread out when it lands, the moisture content is greater than 75%, and it is not good if it is too dry or too wet, so it should be adjusted.

3. Add water and mix well, then put it into pots, cylinders, pools, plastic bags and other containers, seal and ferment at natural temperature for 2-3 days, and then feed when there is fragrant, sweet and alcoholic gas.

4. During large-scale fermentation, it can be directly stacked on a clean cement floor or fermentation tank, and covered with plastic film to seal the fermentation.

Reference recipe for feed fermentation.

After the straw is crushed 5-15%, the okara accounts for about 60%, and the rest can be rice bran, of which the proportion of rice bran and bean dregs can be appropriately adjusted according to the actual situation such as the moisture of the bean dregs. The amount of type II feed starter is added by 1-2.

Take 100 kg of full-price feed purchased in the market, or your own self-formulated full-price feed, add 1 package of roughage degrader, add an appropriate amount of water (add 80 kg of water in winter, add 120 kg of water in summer), stir and mix evenly, put it into a fermentation container, pay attention to compacting and pressing with the greatest force, and cover and seal it with a thick plastic film that is indeed not damaged, seal the edge, and carry out fermentation treatment, fermentation for more than 15 days in winter and more than 5 days in summer.

In terms of strain selection for fermented feed, microecological preparations can be used, or bagged live bacteria dry powder can be used. There is a wide variety of products on the market today. Don't be especially em bacteria, the real and the fake, the real and the fake, it is difficult for the average user to distinguish.

There are only 3 4 manufacturers of real Japanese authorized EM, and there are manufacturers in Nanjing, Jiangxi, and Guangzhou. This test site briefly introduces some products on the current market, but it should be stated that this test site is not selling advertising, and sincerely thinks about the same industry (especially do not buy EM bacteria that have been propagated many times by others). 1, there are em bacteria, enzyme bacteria in the Japanese series.

2. Domestic Vitality 99, Tianjin University of Science and Technology's high-activity straw starter culture. There is also Shenwei (known as China's EM), which is used for planting and environmental protection. Shenwei and Shengwei were developed by Li Weijiong, a professor at China Agricultural University, and have complete intellectual property rights.

However, the strain should be resurrected with brown sugar in advance, and if the silage is added, salt is added, which is conducive to the fermentation of lactic acid bacteria and can also destroy some viruses.

I don't know how big you want to make, what to do with it, what kind of feed to ferment! None of this is the same!

The simple point is the fermentation tank + fermentation + strain. Pay attention to moisture, compaction, airtightness, etc!!

Fermented feed needs to be made by mixing soybean meal, wood flour, starter culture, probiotics and other materials, and the production time changes according to the ambient temperature, the lower the temperature, the longer the fermentation time required. Fermented feed is more conducive to absorption and safer, and can be added to the staple food with a dosage of 5% on weekdays, and about 10% for animals that have just been produced or need to be transported over long distances.

1. Material selection.

To make fermented feed, you can choose soybean meal, wood flour, bran or rice bran, mix it in kilograms according to the ratio of 8:1:1, and then buy 5 8 kg of special agents for fermentation from the market, and also need 5 8 kg of Yishengbao compound bacteria and water.

2. Mixed materials.

All the materials that have just been prepared are mixed in a sealed substrate environment for fermentation, and the fermentation time is determined according to the temperature, and the fermentation time is short when the temperature is high, usually 5 to 7 days. In winter, the temperature is relatively low, and the fermentation time should be more than 15 days.

3. Advantages of feed.

After fermentation, the nutrients of the feed are easier for passive objects to digest and absorb, improve the nutritional level of the feed, and promote the growth of animals. It can also maintain the balance of animal intestinal flora and improve animal immunity. Lactic acid bacteria can inhibit the growth of mold, and the feed is safer.

4. How to use.

Fermented feed is not specifically used as a main ingredient, but is added to the staple food at a rate of 5% during daily feeding. For example, animals that have just been produced, prepared or rocked or transported over long distances can be increased to 10%. In the case of continuous disease among animals, fermented feed can also have a good effect.

1. No matter what kind of raw material formula is used to make fermented feed, raw materials without mildew and pollution should be selected.

2. Mix the fermentation liquid and fermented feed evenly, with a humidity of 40 to 50 percent, and do not drip water when grasping it by hand, and it is appropriate to disperse it at one touch. Farms with mixers will slowly add the fermentation broth to the feed and stir evenly; Farmers who do not have a mixer will spray the fermented liquid in the reed onto the feed, stir it evenly with a shovel, Note: there can be no lumps and water agglomerates, and the clumps and water agglomerates should be rubbed and stirred evenly by hand.

3. Put the configured fermented feed into the fermentation container or a fermented feed bag with a breathing valve, and then seal it, which must be sealed tightly and not breathable.

4. Put it at room temperature, in a rodent-proof place for anaerobic fermentation, according to the season after 3 to 7 days of fermentation, emitting a sweet and sour rich koji aroma, indicating that the fermentation is successful. The bag of fermented feed should be sealed without air leakage to prevent the entry of external bacteria.

5. After successful fermentation, add the fermented feed to the unfermented full-price feed and mix evenly and feed directly. If the fermented feed in the bag is not used up, it should be quickly sealed, and then taken and reused and sealed.
