Abstract
Description
Technical Field
[0001] This invention relates to the field of livestock and poultry feed, and in particular to a feed containing a fermented grain and fruit composition and a method for preparing the same. Background Technology
[0002] my country is the world's largest feed producer, with a total industrial feed output of 252.761 million tons in 2020, generating a total value of over 940 billion yuan, accounting for about one-fifth of global output. However, traditional feed has significant shortcomings in practical application: On the one hand, feed ingredients largely rely on grains such as corn and soybean meal. The large molecules in these ingredients, such as starch and protein, are difficult for livestock and poultry to digest directly and efficiently. They also contain anti-nutritional factors such as phytic acid and non-starch polysaccharides, which not only reduce nutrient absorption and utilization but also easily cause intestinal flora imbalance, leading to diarrhea in piglets and a high feed conversion ratio in fattening pigs. On the other hand, feed ingredients, especially grains such as corn and wheat, are susceptible to mold contamination during storage and transportation. Mycotoxins such as aflatoxin and zearalenone can damage the digestive tract mucosa of livestock and poultry, disrupt the intestinal barrier function, lead to immunosuppression, increase the risk of infectious diseases, and the toxins may also indirectly harm human health through the food chain.
[0003] While feed additives such as probiotics and enzymes, whether single or simply compounded, exist, their effectiveness remains limited. Probiotics have poor tolerance to high temperatures and acidic gastric environments, and are easily inactivated during feed pelleting and digestion, making it difficult for them to colonize the intestines and exert their effects. Although enzymes can degrade some anti-nutritional factors, they lack the ability to regulate the intestinal microecology. Feeds prepared from single grain raw materials have a limited nutritional structure, poor palatability, and cannot meet the nutritional needs of livestock at different growth stages. Furthermore, current feed production processes often employ high-temperature conditioning and spray drying, which are not only energy-intensive but also destroy the active nutrients in the raw materials and generate large amounts of wastewater, contradicting the trend of green and low-carbon production.
[0004] In addition, as consumers demand higher quality livestock and poultry products, traditional feeds, due to their low nutrient conversion efficiency, are prone to problems such as insufficient unsaturated fatty acid content in livestock and poultry muscles, dark meat color, and large water loss, which affect the market competitiveness of the products.
[0005] Therefore, it is of great significance to develop a multifunctional feed that can efficiently provide nutrition, protect intestinal health, degrade mycotoxins, and make efficient use of resources. Summary of the Invention
[0006] The purpose of this invention is to provide a feed containing a grain and fruit fermentation composition to solve the problems of existing feeds that cannot provide efficient nutrition, protect intestinal health, degrade mycotoxins, and efficiently utilize resources.
[0007] The present invention also aims to provide a method for preparing feed containing a grain and fruit fermentation composition.
[0008] In a first aspect, the present invention provides a feed containing a fermented grain and fruit composition, comprising the following components in parts by weight: 50-100 parts of a grain and fruit fermentation composition; 10-20 servings of Biostime; 3-7 parts of organic trace elements; 1-5 parts of mineral premix; Vitamin premix 0.5–3 parts; The grain and fruit fermentation composition includes feed syrup and wet grain and fruit residue.
[0009] By adopting the above technical solutions, the 50-100 part grain and fruit fermentation composition, consisting of feed syrup and wet grain and fruit residue, serves as a functional carrier for feed. Through synergistic enzymatic hydrolysis and fermentation, it breaks down starch polysaccharides and non-starch polysaccharides in grains, as well as pectin and large-molecule sugars in fruits, into easily absorbed nutrients such as glucose, fructose, and small-molecule peptides. These small-molecule substances can be directly absorbed through the intestinal mucosa of livestock and poultry without further breakdown by intestinal digestive enzymes, thus improving the digestibility and absorption rate of protein and carbohydrates. This solves the problems of poor absorption of large-molecule nutrients and high feed conversion ratios, making it particularly suitable for livestock and poultry with weak intestinal digestive capacity.
[0010] Furthermore, the oligosaccharides produced during fermentation can serve as a dedicated nutrient source for beneficial gut bacteria, promoting their proliferation. Simultaneously, the short-chain fatty acids produced can lower the intestinal pH, creating an acidic environment unfavorable to the growth of harmful bacteria and reducing their colonization. The dietary fiber retained in the wet pulp of grains and fruits can also promote intestinal peristalsis, enhance the intestinal mucosal barrier function, reduce the risk of diarrhea in livestock and poultry, and improve intestinal flora imbalance.
[0011] In addition, the synergistic effect of enzymatic hydrolysis and fermentation can destroy the structure of mycotoxins that may exist in grains and fruits. Cellulase and pectinase can open the cell walls that encapsulate toxins, and the detoxification enzymes produced by fermentation microorganisms can break the toxic groups of toxins and degrade them into non-toxic products, thus avoiding toxin damage to the digestive tract mucosa of livestock and poultry and causing immunosuppression. At the same time, it can block the path of toxin transmission to humans through the food chain.
[0012] Adding 10-20 parts of synbiotics can enhance probiotics and immune activation. The prebiotics in synbiotics can specifically provide energy for probiotics, and the probiotics in synbiotics can secrete bacterial toxins to directly inhibit the activity of harmful bacteria. The prebiotics further prevent the colonization of harmful bacteria by competing for intestinal adhesion sites. The two work together to reduce the number of harmful bacteria.
[0013] Adding 3-7 parts of organic trace elements can overcome the shortcomings of inorganic trace elements. Organic trace elements, through their amino acid chelate structure, can avoid antagonistic reactions with phytic acid and tannic acid in feed, and are absorbed by the intestines through amino acid absorption channels. Organic trace elements can also participate in the regulation of intestinal enzyme activity, enhancing the activity of intestinal antioxidant enzymes and reducing intestinal oxidative stress damage. Furthermore, the high absorption of organic trace elements can reduce excretion in feces, thus reducing heavy metal pollution of soil and water during the farming process.
[0014] Adding 3 to 7 parts of mineral premix can build a balanced mineral nutrition and ensure the physiological needs of livestock and poultry; 0.5 to 3 parts of vitamin premix, composed of a variety of vitamins, can improve the quality of livestock and poultry, repair the intestinal barrier, promote the absorption of minerals in the intestine, enhance the decomposition efficiency of the grain and fruit fermentation composition, inhibit fat oxidation in livestock and poultry muscles, prevent dark meat color, and improve meat quality.
[0015] Preferably, the method for preparing the grain and fruit fermentation composition includes the following steps: After crushing the grains and fruits, water is added to make a suspension. Then, an enzyme preparation is added to the suspension for fermentation to obtain a crude fermented product. The crude fermented product is then separated into a wet grain and fruit residue and a diluted grain and fruit syrup. The wet grain and fruit residue is dried and the diluted grain and fruit syrup is concentrated to obtain the grain and fruit fermented composition.
[0016] Preferably, the mass ratio of grains to fruits is 1:(0.1 to 0.3).
[0017] Preferably, the enzyme preparation includes cellulase, saccharifying enzyme, β-mannanase, and pectinase; the amount of cellulase added is 0.01–300 U / g dry substrate; the amount of saccharifying enzyme added is 0.02–300 U / g dry substrate; the amount of β-mannanase added is 0.01–300 U / g dry substrate; and the amount of pectinase added is 0.01–400 U / g dry substrate.
[0018] Preferably, the grains include one or more of puffed corn, soybean meal, wheat and rice bran meal; the fruits include one or more of apples, bananas, oranges and pears.
[0019] Preferably, the fermentation time is 50–100 hours.
[0020] Preferably, the synbiotics include Bacillus lactis-fructooligosaccharide synbiotics and Lactobacillus plantarum-chitosan oligosaccharide synbiotics.
[0021] More preferably, the mass ratio of Bacillus lactis to fructooligosaccharides is 1:(2-3); and the mass ratio of Lactobacillus plantarum to chitosan oligosaccharides is 1:(2-3).
[0022] Preferably, the organic trace elements include one or more of the following: iron glycinate, zinc methionine, copper methionine, zinc glycinate, selenium methionine, and manganese glycinate.
[0023] Preferably, the mineral premix comprises calcium carbonate, dicalcium phosphate and sodium chloride in a ratio of (2-3):(1-2):(0.5-1).
[0024] Preferably, the vitamin premix comprises vitamin A, vitamin D, vitamin E and B vitamins in a mass ratio of 1:(1-2):(0.5-1):(0.05-0.5).
[0025] Secondly, the present invention provides a method for preparing a feed containing a grain and fruit fermentation composition, comprising the following steps: S1. Weigh out 50-100 parts of the grain and fruit fermentation composition, 10-20 parts of the synbiotic, 3-7 parts of the organic trace elements, 1-5 parts of the mineral premix, and 0.5-3 parts of the vitamin premix. S2. Premix the weighed synbiotic, organic trace elements, mineral premix, and vitamin premix, add the grain and fruit fermentation composition, mix evenly, granulate, and cool to obtain the final product.
[0026] The beneficial effects of this invention are: 1. By using the feed of the present invention, synergistic effects of nutrient supply and intestinal health protection can be achieved. The grain and fruit fermentation composition transforms macromolecular nutrients into easily absorbed small molecules through enzymatic hydrolysis and fermentation, thereby improving the nutrient digestibility and absorption rate. At the same time, the oligosaccharides, short-chain fatty acids and synbiotics produced synergistically regulate the intestinal flora, reduce the colonization of harmful bacteria, reduce the risk of diarrhea in livestock and poultry, improve the intestinal microecological balance, and degrade mycotoxins through enzymatic hydrolysis and fermentation, thereby avoiding toxin damage to the digestive tract mucosa and the induction of immunosuppression.
[0027] 2. The vitamin premix of the present invention can inhibit the oxidation of muscle fat in livestock and poultry, improve meat color and reduce drip loss. The organic trace elements and mineral premix ensure the physiological needs and growth performance of livestock and poultry. Under the synergistic effect of the components, the palatability and nutritional balance of the feed are improved, promoting the increase of feed intake and daily weight gain of livestock and poultry, and reducing breeding costs.

Weigh 40 parts by weight of the grain and fruit fermentation composition prepared in Example 1, 15 parts by weight of Bacillus lactis-fructooligosaccharide synbiotic in a mass ratio of 1:3, 5 parts by weight of glycine iron and methionine zinc in a mass ratio of 1:1, 3 parts by weight of calcium carbonate, calcium hydrogen phosphate and sodium chloride in a mass ratio of 1:1:1, and 2 parts by weight of vitamin A, vitamin D, vitamin E and B vitamins in a mass ratio of 1:1:0.5:0.2.

[0041] Comparative Example 3, a feed containing a fermented grain and fruit composition, differs from Example 1 only in that it does not contain synbiotics.
[0042] Comparative Example 4, a feed containing a fermented grain and fruit composition, differs from Example 1 only in that no organic trace elements are added.
[0043] Performance testing
[0044] This experiment used 270 weaned piglets aged 30 days, which were randomly divided into 9 groups of 30 piglets each, with 8 experimental groups and one control group.
[0045] The experimental group used feed containing fermented grain and fruit compositions prepared according to Examples 1-4 and Comparative Examples 1-4; the control group used a basal diet without any treatment. The experiment lasted 21 days. During the experiment, the piglets' feeding, fecal condition, and diarrhea were observed daily. Initial weight was recorded before the experiment, and final weight was recorded after the experiment. Daily feed intake and daily weight gain were also recorded. Performance test results are shown in Table 1. Table 1 Performance test results
[0046] According to Table 1, and in conjunction with Example 1 and Comparative Example 1, it can be seen that the average final weight, average daily weight gain, average daily feed intake, and diarrhea rate of Comparative Example 1 are all lower than those of Example 1. The reason for this is that the number of parts of the grain and fruit fermentation composition in Comparative Example 1 is 40 parts, which means that the content of easily absorbed small molecule nutrients (glucose, fructose, and small molecule peptides) in the feed is insufficient, which cannot fully meet the needs of weaned piglets for efficient nutrition, thus limiting the increase in daily weight gain. At the same time, the total amount of oligosaccharides, short-chain fatty acids, and dietary fiber produced by fermentation is reduced, which weakens the effect of promoting the proliferation of beneficial bacteria in the intestines and reduces the effect of inhibiting harmful bacteria. The ability to maintain the balance of the intestinal microecology is insufficient, so the diarrhea rate is higher than that of Example 1. In addition, the insufficient nutrient supply indirectly affects the piglets' enthusiasm for feed intake, resulting in an average daily feed intake lower than that of Example 1.
[0047] Combining Example 1 and Comparative Example 2, it can be seen that the average final weight, average daily weight gain, average daily feed intake, and diarrhea rate of Comparative Example 2 are all lower than those of Example 1. The reason is that the ratio of grain to fruit in the grain-fruit fermentation composition of Comparative Example 2 is 1:0.5. The high fruit content leads to the production of too much acidic substances during fermentation, resulting in a low overall pH value of the feed, which irritates the digestive tract mucosa of weaned piglets and causes an increase in the diarrhea rate. In addition, the fruit cannot meet the comprehensive nutritional needs of piglets for growth, resulting in low daily weight gain and average final weight.
[0048] Combining Example 1 and Comparative Example 3, it can be seen that the average final weight, average daily weight gain, average daily feed intake, and diarrhea rate of Comparative Example 3 are all lower than those of Example 1. The reason is that Comparative Example 3 did not add synbiotics, so the feed only relied on the small amount of beneficial bacteria naturally present in the grain and fruit fermentation composition, which was difficult to proliferate in large quantities in the piglet's intestines to form a dominant flora. This weakened the ability to inhibit harmful bacteria, increased the risk of intestinal flora imbalance, and increased the diarrhea rate. At the same time, the insufficient number of probiotics could not effectively activate the intestinal mucosal immunity, and the piglet's own disease resistance and nutrient absorption efficiency decreased, resulting in a slower increase in daily weight gain and average final weight. In addition, the poor intestinal health indirectly affected feed intake, making the average daily feed intake lower than that of Example 1.
[0049] Combining Example 1 and Comparative Example 4, it can be seen that the average final weight, average daily weight gain, average daily feed intake, and diarrhea rate of Comparative Example 4 are all lower than those of Example 1. The reason is that Comparative Example 4 did not add organic trace elements, so piglets could not efficiently absorb the key trace elements iron and zinc through amino acid chelation channels. Insufficient iron leads to reduced hemoglobin synthesis, decreased oxygen transport capacity, and reduced cell metabolic efficiency, affecting growth and development speed. Zinc deficiency weakens the intestinal mucosal barrier function, increases the risk of harmful bacteria invasion, and leads to an increased diarrhea rate. At the same time, trace elements participate in the regulation of the activity of various digestive enzymes. Deficiency will reduce the decomposition efficiency of nutrients in the grain and fruit fermentation composition, increase undigested nutrient residues, further affect daily weight gain and average final weight. In addition, intestinal discomfort and insufficient nutrient absorption together lead to a decrease in the piglets' enthusiasm for feed intake, and the average daily feed intake is lower than that of Example 1.
[0050] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
