Biofermentation of sweet potato feed practices and benefits

Sweet potatoes are annual herbaceous plants that are excellently juicy and can produce nutrients such as starch, protein, sugar, fat, phosphorus, calcium, iron, carotene, and vitamins B1, B2, C, and niacin, linoleic acid, etc. It is an excellent energy feed and is widely grown in the south. It is often used as a feed for livestock after fermentation, which is convenient for storage and saves pig feed costs.

1. Raw material formula: Sweet potatoes or sweet potato vines to be fermented can be washed, mixed and smashed, and then crushed into potato pulp and then compounded and fermented. Due to the different nutritional requirements of piglets, sows and fat pigs, the composition of fermentation raw materials should also be different, but due to the low protein content of sweet potatoes, calcium, phosphorus, sodium and other minerals and vitamins are low, long time a single sweet potato feed Pigs can cause indigestion, affect the balanced absorption of various nutrients, cause pigs to be uncomfortable and uneasy, and it is best to mix other raw materials in the process of fermenting sweet potatoes so as to complement each other and promote the healthy growth of pigs. Jinbao sweet potato starter is conducive to feed fermentation, and improve feed taste and nutrition.

After the material is formulated according to the recipe in the above table, the second step can be performed.
2, moisture control: the composition of a good fermented material to adjust the moisture to 65-70%, water determination method: grasping a handful of material, see the watermark between the fingers but not dripping, landing that is suitable for casual, slow water fermentation Poor moisture permeability, but also will lead to spoilage fermentation odor.
3, temperature adjustment: fermentation start temperature should be faster than 15-20 degrees fermentation.
4, sealed fermentation: the material should be completely sealed but can not be compressed; when using non-strict tightness of the container fermentation, the outside should be wrapped or wrapped in airtight plastic bags or plastic cloth, and fastened tightly, absolutely sealed; In the process of sealed fermentation, it cannot be disassembled and tossed, and generally it can be finished in 1-3 days of fermentation (the finished product has aroma or frankincense, acid and aroma).
After the fermentation, the finished product should be sealed immediately after each feeding. It is best to use a large bag or a large pool to add 10-30 kilograms of the specifications of the independent small bag at the same time fermentation; fermentation of the finished product can be used separately sealed or preserved Dry dehydration, low-temperature drying, or granulation, etc.; the finished product after fermentation should be fed as required. When trials are conducted in small batches, the total weight of single batch fermentation materials should not be less than 100 kg.

1, save feed costs. Every three kilograms of fresh sweet potatoes is equal to one kilogram of fine feed. Each kilogram of live pigs feeds 4-5 kilograms of refined feed per day. The unit price of each kilogram is 1.35 yuan, and the price of fresh potatoes listed on new potatoes does not exceed 0.25 per kilogram. Pigs can save feed costs by 5.5 yuan. And the fermented sweet potato (leaf stem) is partially transformed into a bacterial protein feed. Using this fermented material to prepare a full-priced feed can also reduce the amount of protein feed used by about 50%, and can eliminate the use of soybean meal, thereby greatly reducing the total cost of feeding.
2. Improve nutritional value. The feed fermented by the ginseng sweet potato feed starter can be decomposed in advance by the microorganisms during the fermentation process. The nutrients such as glucose and protein in the feed can be decomposed in advance, easily absorbed after the pig eats, and there is a large amount of probiotics in the fermented feed. The harmful bacteria in the feed, the pigs absorb a large number of beneficial bacteria after eating, and reduce the disease of the pig's digestive tract. At the same time, a large amount of plant fibers can be added to the fermented feed, which can convert the plant fibers into easily absorbable plant proteins, and can also decompose part of the nutrients. It is rich in 18 amino acids and trace elements.
3, improve feed palatability. Because sweet potato is rich in nutrients, the fiber, protein, fat, potassium, phosphorus, and calcium are all improved after the fermentation of jinbao sweet potato starter. The taste is excellent, the smell is fresh, and it does not contain any chemical elements. It is a pure natural green food. Eat and eat more, to promote the bright color of pork, a few years to get the unanimous praise of consumers. In addition, sweet potatoes do not need to be cooked after feeding, which can greatly save fuel and labor costs.
4, feed more secure. Non-fermented sweet potato can easily cause pig diarrhea and intestinal dyspepsia. Severe symptoms may lead to poisoning. Symptoms are increased body temperature, poor appetite, dry black or pelleted feces, and may be accompanied by blood. Wait. Therefore, sweet potatoes are best to be fed to pigs after being fermented by Jinbao Sweet Potato Fermentation Starter, not only without any side effects, but rely on the life activities and metabolites of the “functional” microorganisms contained in the sweet potato feed starter so that the sweet potatoes are poisonous. Harmful substances are degraded and removed, which greatly improves feed safety.
5, enhance the resistance of pigs. It can also increase the pig's resistance, the presence of a large number of probiotics in the sweet potato after fermentation, inhibiting the harmful bacteria in the feed, supplementing the population and quantity of beneficial microorganisms in the intestine of the pig, preventing the colonization and growth and reproduction of pathogenic microorganisms, and forming a “dominant beneficial bacteria”. Group", conducive to the healthy growth of pigs, reduce drug costs, enhance meat quality
6, improve feed utilization. The powerful microbial flora contained in the Jinbao Sweet Potato Starter can destroy the tough cell walls of plants such as sweet potatoes, and converts the hardly degradable “macromolecules” such as cellulose and pectin into monosaccharides and oligosaccharides. "Molecule" substances, and generate a variety of organic acids, vitamins, biological enzymes, amino acids and many other unknown growth factors, greatly improve the nutritional level and digestion and utilization of sweet potatoes, while the product also contains trace elements required for animal growth, Enzymes, etc., provide comprehensive nutrition; the phenomenon of “eat without food” and “food without meat” has been completely changed.
